PrintWriter

open class PrintWriter : Writer

kotlin.Any
↳	java.io.Writer
	↳	java.io.PrintWriter

Prints formatted representations of objects to a text-output stream. This class implements all of the print methods found in PrintStream. It does not contain methods for writing raw bytes, for which a program should use unencoded byte streams.

Unlike the PrintStream class, if automatic flushing is enabled it will be done only when one of the println, printf, or format methods is invoked, rather than whenever a newline character happens to be output. These methods use the platform's own notion of line separator rather than the newline character.

Methods in this class never throw I/O exceptions, although some of its constructors may. The client may inquire as to whether any errors have occurred by invoking checkError().

This class always replaces malformed and unmappable character sequences with the charset's default replacement string. The java.nio.charset.CharsetEncoder class should be used when more control over the encoding process is required.

Inherited functions

From class Writer

Writer!

nullWriter()

Returns a new Writer which discards all characters. The returned stream is initially open. The stream is closed by calling the close() method. Subsequent calls to close() have no effect.

While the stream is open, the append(char), append(CharSequence), append(CharSequence, int, int), flush(), write(int), write(char[]), and write(char[], int, int) methods do nothing. After the stream has been closed, these methods all throw IOException.

The object used to synchronize operations on the returned Writer is not specified.

Properties
Writer!	`out` The underlying character-output stream of this `PrintWriter`.

Inherited properties

From class Writer

Any!

lock

The object used to synchronize operations on this stream. For efficiency, a character-stream object may use an object other than itself to protect critical sections. A subclass should therefore use the object in this field rather than this or a synchronized method.

Public methods

append

Added in API level 1

open fun append(c: Char): PrintWriter

Appends the specified character to this writer.

An invocation of this method of the form out.append(c) behaves in exactly the same way as the invocation

<code>out.write(c)
  </code>

Parameters
`c`	Char: The 16-bit character to append

Return
`PrintWriter`	This writer

Exceptions
`java.io.IOException`	If an I/O error occurs

append

Added in API level 1

open fun append(csq: CharSequence?): PrintWriter

Appends the specified character sequence to this writer.

An invocation of this method of the form out.append(csq) behaves in exactly the same way as the invocation

<code>out.write(csq.toString())
  </code>

Depending on the specification of toString for the character sequence csq, the entire sequence may not be appended. For instance, invoking the toString method of a character buffer will return a subsequence whose content depends upon the buffer's position and limit.

Parameters
`csq`	CharSequence?: The character sequence to append. If `csq` is `null`, then the four characters `"null"` are appended to this writer.

Return
`PrintWriter`	This writer

Exceptions
`java.io.IOException`	If an I/O error occurs

append

Added in API level 1

open fun append(
    csq: CharSequence?, 
    start: Int, 
    end: Int
): PrintWriter

Appends a subsequence of the specified character sequence to this writer.

An invocation of this method of the form out.append(csq, start, end) when csq is not null, behaves in exactly the same way as the invocation

<code>out.write(csq.subSequence(start, end).toString())
  </code>

Parameters
`csq`	CharSequence?: The character sequence from which a subsequence will be appended. If `csq` is `null`, then characters will be appended as if `csq` contained the four characters `"null"`.
`start`	Int: The index of the first character in the subsequence
`end`	Int: The index of the character following the last character in the subsequence

Return
`PrintWriter`	This writer

Exceptions
`java.lang.IndexOutOfBoundsException`	If `start` or `end` are negative, `start` is greater than `end`, or `end` is greater than `csq.length()`
`java.io.IOException`	If an I/O error occurs

checkError

Added in API level 1

Return
`Boolean`	`true` if the print stream has encountered an error, either on the underlying output stream or during a format conversion.
