LocalTime

public final class LocalTime
extends Object implements Comparable<LocalTime>, Serializable, Temporal, TemporalAdjuster

java.lang.Object
↳	java.time.LocalTime

A time without a time-zone in the ISO-8601 calendar system, such as 10:15:30.

LocalTime is an immutable date-time object that represents a time, often viewed as hour-minute-second. Time is represented to nanosecond precision. For example, the value "13:45.30.123456789" can be stored in a LocalTime.

This class does not store or represent a date or time-zone. Instead, it is a description of the local time as seen on a wall clock. It cannot represent an instant on the time-line without additional information such as an offset or time-zone.

The ISO-8601 calendar system is the modern civil calendar system used today in most of the world. This API assumes that all calendar systems use the same representation, this class, for time-of-day.

Public methods

adjustInto

Added in API level 26

public Temporal adjustInto (Temporal temporal)

Adjusts the specified temporal object to have the same time as this object.

This returns a temporal object of the same observable type as the input with the time changed to be the same as this.

The adjustment is equivalent to using Temporal.with(TemporalField, long) passing ChronoField.NANO_OF_DAY as the field.

In most cases, it is clearer to reverse the calling pattern by using Temporal.with(TemporalAdjuster):

   // these two lines are equivalent, but the second approach is recommended
   temporal = thisLocalTime.adjustInto(temporal);
   temporal = temporal.with(thisLocalTime);

This instance is immutable and unaffected by this method call.

Parameters
`temporal`	`Temporal`: the target object to be adjusted, not null

Returns
`Temporal`	the adjusted object, not null

Throws
`DateTimeException`	if unable to make the adjustment
`ArithmeticException`	if numeric overflow occurs

atDate

Added in API level 26

public LocalDateTime atDate (LocalDate date)

Combines this time with a date to create a LocalDateTime.

This returns a LocalDateTime formed from this time at the specified date. All possible combinations of date and time are valid.

Parameters
`date`	`LocalDate`: the date to combine with, not null

Returns
`LocalDateTime`	the local date-time formed from this time and the specified date, not null

atOffset

Added in API level 26

public OffsetTime atOffset (ZoneOffset offset)

Combines this time with an offset to create an OffsetTime.

This returns an OffsetTime formed from this time at the specified offset. All possible combinations of time and offset are valid.

Parameters
`offset`	`ZoneOffset`: the offset to combine with, not null

Returns
`OffsetTime`	the offset time formed from this time and the specified offset, not null

compareTo

Added in API level 26

public int compareTo (LocalTime other)

Compares this time to another time.

The comparison is based on the time-line position of the local times within a day. It is "consistent with equals", as defined by Comparable.

Parameters
`other`	`LocalTime`: the other time to compare to, not null

Returns
`int`	the comparator value, negative if less, positive if greater

Throws
`NullPointerException`	if `other` is null

equals

Added in API level 26

public boolean equals (Object obj)

Checks if this time is equal to another time.

The comparison is based on the time-line position of the time within a day.

Only objects of type LocalTime are compared, other types return false. To compare the date of two TemporalAccessor instances, use ChronoField.NANO_OF_DAY as a comparator.

Parameters
`obj`	`Object`: the object to check, null returns false

Returns
`boolean`	true if this is equal to the other time

format

Added in API level 26

public String format (DateTimeFormatter formatter)

Formats this time using the specified formatter.

This time will be passed to the formatter to produce a string.

Parameters
`formatter`	`DateTimeFormatter`: the formatter to use, not null

Returns
`String`	the formatted time string, not null

Throws
`DateTimeException`	if an error occurs during printing

from

Added in API level 26

public static LocalTime from (TemporalAccessor temporal)

Obtains an instance of LocalTime from a temporal object.

This obtains a local time based on the specified temporal. A TemporalAccessor represents an arbitrary set of date and time information, which this factory converts to an instance of LocalTime.

The conversion uses the TemporalQueries.localTime() query, which relies on extracting the NANO_OF_DAY field.

This method matches the signature of the functional interface TemporalQuery allowing it to be used as a query via method reference, LocalTime::from.

Parameters
`temporal`	`TemporalAccessor`: the temporal object to convert, not null

Returns
`LocalTime`	the local time, not null

Throws
`DateTimeException`	if unable to convert to a `LocalTime`

get

Added in API level 26

public int get (TemporalField field)

Gets the value of the specified field from this time as an int.

This queries this time for the value of the specified field. The returned value will always be within the valid range of values for the field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this time, except NANO_OF_DAY and MICRO_OF_DAY which are too large to fit in an int and throw an UnsupportedTemporalTypeException. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.

Parameters
`field`	`TemporalField`: the field to get, not null

Returns
`int`	the value for the field

Throws
`DateTimeException`	if a value for the field cannot be obtained or the value is outside the range of valid values for the field
`UnsupportedTemporalTypeException`	if the field is not supported or the range of values exceeds an `int`
`ArithmeticException`	if numeric overflow occurs

getHour

Added in API level 26

public int getHour ()

Gets the hour-of-day field.

Returns
`int`	the hour-of-day, from 0 to 23

getLong

Added in API level 26

public long getLong (TemporalField field)

Gets the value of the specified field from this time as a long.

This queries this time for the value of the specified field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this time. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

Parameters
`field`	`TemporalField`: the field to get, not null

Returns
`long`	the value for the field

Throws
`DateTimeException`	if a value for the field cannot be obtained

Parameters
`other`	`LocalTime`: the other time to compare to, not null

Returns
`boolean`	true if this point is before the specified time

Throws
`NullPointerException`	if `other` is null

isSupported

Added in API level 26

public boolean isSupported (TemporalUnit unit)

Checks if the specified unit is supported.

This checks if the specified unit can be added to, or subtracted from, this time. If false, then calling the plus(long, java.time.temporal.TemporalUnit) and minus methods will throw an exception.

If the unit is a ChronoUnit then the query is implemented here. The supported units are:

NANOS
MICROS
MILLIS
SECONDS
MINUTES
HOURS
HALF_DAYS

All other ChronoUnit instances will return false.

If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.isSupportedBy(Temporal) passing this as the argument. Whether the unit is supported is determined by the unit.

Parameters
`unit`	`TemporalUnit`: the unit to check, null returns false

Returns
`boolean`	true if the unit can be added/subtracted, false if not

isSupported

Added in API level 26

public boolean isSupported (TemporalField field)

Checks if the specified field is supported.

This checks if this time can be queried for the specified field. If false, then calling the range, get and with(java.time.temporal.TemporalField, long) methods will throw an exception.

If the field is a ChronoField then the query is implemented here. The supported fields are:

NANO_OF_SECOND
NANO_OF_DAY
MICRO_OF_SECOND
MICRO_OF_DAY
MILLI_OF_SECOND
MILLI_OF_DAY

CLOCK_HOUR_OF_AMPM
HOUR_OF_DAY
CLOCK_HOUR_OF_DAY
AMPM_OF_DAY

All other ChronoField instances will return false.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.isSupportedBy(TemporalAccessor) passing this as the argument. Whether the field is supported is determined by the field.

Parameters
`field`	`TemporalField`: the field to check, null returns false

Returns
`boolean`	true if the field is supported on this time, false if not

minus

Added in API level 26

public LocalTime minus (TemporalAmount amountToSubtract)

Returns a copy of this time with the specified amount subtracted.

This returns a LocalTime, based on this one, with the specified amount subtracted. The amount is typically Duration but may be any other type implementing the TemporalAmount interface.

The calculation is delegated to the amount object by calling TemporalAmount.subtractFrom(Temporal). The amount implementation is free to implement the subtraction in any way it wishes, however it typically calls back to minus(long, java.time.temporal.TemporalUnit). Consult the documentation of the amount implementation to determine if it can be successfully subtracted.

This instance is immutable and unaffected by this method call.

Parameters
`amountToSubtract`	`TemporalAmount`: the amount to subtract, not null

                TemporalUnit unit)

Returns a copy of this time with the specified amount subtracted.

This returns a LocalTime, based on this one, with the amount in terms of the unit subtracted. If it is not possible to subtract the amount, because the unit is not supported or for some other reason, an exception is thrown.

This method is equivalent to plus(long, java.time.temporal.TemporalUnit) with the amount negated. See that method for a full description of how addition, and thus subtraction, works.

This instance is immutable and unaffected by this method call.

parse

Added in API level 26

public static LocalTime parse (CharSequence text)

Obtains an instance of LocalTime from a text string such as 10:15.

The string must represent a valid time and is parsed using DateTimeFormatter.ISO_LOCAL_TIME.

Returns
`LocalTime`	the parsed local time, not null

Throws
`DateTimeParseException`	if the text cannot be parsed

plus

Added in API level 26

public LocalTime plus (TemporalAmount amountToAdd)

Returns a copy of this time with the specified amount added.

This returns a LocalTime, based on this one, with the specified amount added. The amount is typically Duration but may be any other type implementing the TemporalAmount interface.

The calculation is delegated to the amount object by calling TemporalAmount.addTo(Temporal). The amount implementation is free to implement the addition in any way it wishes, however it typically calls back to plus(long, java.time.temporal.TemporalUnit). Consult the documentation of the amount implementation to determine if it can be successfully added.

This instance is immutable and unaffected by this method call.

Parameters
`amountToAdd`	`TemporalAmount`: the amount to add, not null

Returns
`LocalTime`	a `LocalTime` based on this time with the addition made, not null

Throws
`DateTimeException`	if the addition cannot be made
`ArithmeticException`	if numeric overflow occurs

plus

Added in API level 26

public LocalTime plus (long amountToAdd, 
                TemporalUnit unit)

Returns a copy of this time with the specified amount added.

This returns a LocalTime, based on this one, with the amount in terms of the unit added. If it is not possible to add the amount, because the unit is not supported or for some other reason, an exception is thrown.

If the field is a ChronoUnit then the addition is implemented here. The supported fields behave as follows:

NANOS - Returns a LocalTime with the specified number of nanoseconds added. This is equivalent to plusNanos(long).
MICROS - Returns a LocalTime with the specified number of microseconds added. This is equivalent to plusNanos(long) with the amount multiplied by 1,000.
MILLIS - Returns a LocalTime with the specified number of milliseconds added. This is equivalent to plusNanos(long) with the amount multiplied by 1,000,000.
SECONDS - Returns a LocalTime with the specified number of seconds added. This is equivalent to plusSeconds(long).
MINUTES - Returns a LocalTime with the specified number of minutes added. This is equivalent to plusMinutes(long).
HOURS - Returns a LocalTime with the specified number of hours added. This is equivalent to plusHours(long).
HALF_DAYS - Returns a LocalTime with the specified number of half-days added. This is equivalent to plusHours(long) with the amount multiplied by 12.

All other ChronoUnit instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.addTo(Temporal, long) passing this as the argument. In this case, the unit determines whether and how to perform the addition.

This instance is immutable and unaffected by this method call.

Parameters
`amountToAdd`	`long`: the amount of the unit to add to the result, may be negative
`unit`	`TemporalUnit`: the unit of the amount to add, not null

Returns
`LocalTime`	a `LocalTime` based on this time with the specified amount added, not null

Throws
`DateTimeException`	if the addition cannot be made
`UnsupportedTemporalTypeException`	if the unit is not supported
`ArithmeticException`	if numeric overflow occurs

query

Added in API level 26

public R query (TemporalQuery<R> query)

Queries this time using the specified query.

This queries this time using the specified query strategy object. The TemporalQuery object defines the logic to be used to obtain the result. Read the documentation of the query to understand what the result of this method will be.

The result of this method is obtained by invoking the TemporalQuery.queryFrom(TemporalAccessor) method on the specified query passing this as the argument.

Parameters
`query`	`TemporalQuery`: the query to invoke, not null

Returns
`R`	the query result, null may be returned (defined by the query)

`ArithmeticException`	if numeric overflow occurs (defined by the query)

range

Added in API level 26

public ValueRange range (TemporalField field)

Gets the range of valid values for the specified field.

The range object expresses the minimum and maximum valid values for a field. This time is used to enhance the accuracy of the returned range. If it is not possible to return the range, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return appropriate range instances. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.rangeRefinedBy(TemporalAccessor) passing this as the argument. Whether the range can be obtained is determined by the field.

Parameters
`field`	`TemporalField`: the field to query the range for, not null

Returns
`ValueRange`	the range of valid values for the field, not null

Throws
`DateTimeException`	if the range for the field cannot be obtained

                ZoneOffset offset)

Converts this LocalTime to the number of seconds since the epoch of 1970-01-01T00:00:00Z.

This combines this local time with the specified date and offset to calculate the epoch-second value, which is the number of elapsed seconds from 1970-01-01T00:00:00Z. Instants on the time-line after the epoch are positive, earlier are negative.

Parameters
`date`	`LocalDate`: the local date, not null
`offset`	`ZoneOffset`: the zone offset, not null

Returns
`long`	the number of seconds since the epoch of 1970-01-01T00:00:00Z, may be negative

Returns
`long`	the nano of day equivalent to this time

toSecondOfDay

Added in API level 26

public int toSecondOfDay ()

Extracts the time as seconds of day, from 0 to 24 * 60 * 60 - 1.

Returns
`int`	the second-of-day equivalent to this time

toString

Added in API level 26

public String toString ()

Outputs this time as a String, such as 10:15.

The output will be one of the following ISO-8601 formats:

HH:mm
HH:mm:ss
HH:mm:ss.SSS
HH:mm:ss.SSSSSS
HH:mm:ss.SSSSSSSSS

The format used will be the shortest that outputs the full value of the time where the omitted parts are implied to be zero.

Returns
`String`	a string representation of this time, not null

truncatedTo

Added in API level 26

public LocalTime truncatedTo (TemporalUnit unit)

Returns a copy of this LocalTime with the time truncated.

Truncation returns a copy of the original time with fields smaller than the specified unit set to zero. For example, truncating with the minutes unit will set the second-of-minute and nano-of-second field to zero.

The unit must have a duration that divides into the length of a standard day without remainder. This includes all supplied time units on ChronoUnit and DAYS. Other units throw an exception.

This instance is immutable and unaffected by this method call.

Parameters
`unit`	`TemporalUnit`: the unit to truncate to, not null

Returns
`LocalTime`	a `LocalTime` based on this time with the time truncated, not null

Throws
`DateTimeException`	if unable to truncate
`UnsupportedTemporalTypeException`	if the unit is not supported

until

Added in API level 26

public long until (Temporal endExclusive, 
                TemporalUnit unit)

Calculates the amount of time until another time in terms of the specified unit.

This calculates the amount of time between two LocalTime objects in terms of a single TemporalUnit. The start and end points are this and the specified time. The result will be negative if the end is before the start. The Temporal passed to this method is converted to a LocalTime using from(java.time.temporal.TemporalAccessor). For example, the amount in hours between two times can be calculated using startTime.until(endTime, HOURS).

The calculation returns a whole number, representing the number of complete units between the two times. For example, the amount in hours between 11:30 and 13:29 will only be one hour as it is one minute short of two hours.

There are two equivalent ways of using this method. The first is to invoke this method. The second is to use TemporalUnit.between(Temporal, Temporal):

   // these two lines are equivalent
   amount = start.until(end, MINUTES);
   amount = MINUTES.between(start, end);

The choice should be made based on which makes the code more readable.

The calculation is implemented in this method for ChronoUnit. The units NANOS, MICROS, MILLIS, SECONDS, MINUTES, HOURS and HALF_DAYS are supported. Other ChronoUnit values will throw an exception.

If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.between(Temporal, Temporal) passing this as the first argument and the converted input temporal as the second argument.

This instance is immutable and unaffected by this method call.

Parameters
`endExclusive`	`Temporal`: the end time, exclusive, which is converted to a `LocalTime`, not null
`unit`	`TemporalUnit`: the unit to measure the amount in, not null

Returns
`long`	the amount of time between this time and the end time

Throws
`DateTimeException`	if the amount cannot be calculated, or the end temporal cannot be converted to a `LocalTime`
`UnsupportedTemporalTypeException`	if the unit is not supported
`ArithmeticException`	if numeric overflow occurs

with

Added in API level 26

public LocalTime with (TemporalField field, 
                long newValue)

Returns a copy of this time with the specified field set to a new value.

This returns a LocalTime, based on this one, with the value for the specified field changed. This can be used to change any supported field, such as the hour, minute or second. If it is not possible to set the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the adjustment is implemented here. The supported fields behave as follows:

NANO_OF_SECOND - Returns a LocalTime with the specified nano-of-second. The hour, minute and second will be unchanged.
NANO_OF_DAY - Returns a LocalTime with the specified nano-of-day. This completely replaces the time and is equivalent to ofNanoOfDay(long).
MICRO_OF_SECOND - Returns a LocalTime with the nano-of-second replaced by the specified micro-of-second multiplied by 1,000. The hour, minute and second will be unchanged.
MICRO_OF_DAY - Returns a LocalTime with the specified micro-of-day. This completely replaces the time and is equivalent to using ofNanoOfDay(long) with the micro-of-day multiplied by 1,000.
MILLI_OF_SECOND - Returns a LocalTime with the nano-of-second replaced by the specified milli-of-second multiplied by 1,000,000. The hour, minute and second will be unchanged.
MILLI_OF_DAY - Returns a LocalTime with the specified milli-of-day. This completely replaces the time and is equivalent to using ofNanoOfDay(long) with the milli-of-day multiplied by 1,000,000.
SECOND_OF_MINUTE - Returns a LocalTime with the specified second-of-minute. The hour, minute and nano-of-second will be unchanged.
SECOND_OF_DAY - Returns a LocalTime with the specified second-of-day. The nano-of-second will be unchanged.
MINUTE_OF_HOUR - Returns a LocalTime with the specified minute-of-hour. The hour, second-of-minute and nano-of-second will be unchanged.
MINUTE_OF_DAY - Returns a LocalTime with the specified minute-of-day. The second-of-minute and nano-of-second will be unchanged.
HOUR_OF_AMPM - Returns a LocalTime with the specified hour-of-am-pm. The AM/PM, minute-of-hour, second-of-minute and nano-of-second will be unchanged.
CLOCK_HOUR_OF_AMPM - Returns a LocalTime with the specified clock-hour-of-am-pm. The AM/PM, minute-of-hour, second-of-minute and nano-of-second will be unchanged.
HOUR_OF_DAY - Returns a LocalTime with the specified hour-of-day. The minute-of-hour, second-of-minute and nano-of-second will be unchanged.
CLOCK_HOUR_OF_DAY - Returns a LocalTime with the specified clock-hour-of-day. The minute-of-hour, second-of-minute and nano-of-second will be unchanged.
AMPM_OF_DAY - Returns a LocalTime with the specified AM/PM. The hour-of-am-pm, minute-of-hour, second-of-minute and nano-of-second will be unchanged.

In all cases, if the new value is outside the valid range of values for the field then a DateTimeException will be thrown.

All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.adjustInto(Temporal, long) passing this as the argument. In this case, the field determines whether and how to adjust the instant.

This instance is immutable and unaffected by this method call.

Parameters
`field`	`TemporalField`: the field to set in the result, not null
`newValue`	`long`: the new value of the field in the result

Returns
`LocalTime`	a `LocalTime` based on `this` with the specified field set, not null

Throws
`DateTimeException`	if the field cannot be set
`UnsupportedTemporalTypeException`	if the field is not supported
`ArithmeticException`	if numeric overflow occurs
