public final int get(@IntRange(from = 0) int index)

Returns the element at the given index or throws IndexOutOfBoundsException if the index is out of bounds of this collection.

public final @NonNull IntRange getIndices()

Returns an IntRange of the valid indices for this IntList.

public final @IntRange(from = -1) int getLastIndex()

Returns the last valid index in the IntList. This can be -1 when the list is empty.

public final @IntRange(from = 0) int getSize()

The number of elements in the IntList.

public int hashCode()

Returns a hash code based on the contents of the IntList.

public final int indexOf(int element)

Returns the index of element in the IntList or -1 if element is not there.

public final int indexOfFirst(
    @NonNull Function1<@NonNull Integer, @NonNull Boolean> predicate
)

Returns the index if the first element in the IntList for which predicate returns true.

public final boolean isEmpty()

Returns true if the IntList has no elements in it or false otherwise.

public final boolean isNotEmpty()

public final @NonNull String joinToString(
    @NonNull CharSequence separator,
    @NonNull CharSequence prefix,
    @NonNull CharSequence postfix,
    int limit,
    @NonNull CharSequence truncated
)

Creates a String from the elements separated by separator and using prefix before and postfix after, if supplied.

When a non-negative value of limit is provided, a maximum of limit items are used to generate the string. If the collection holds more than limit items, the string is terminated with truncated.

public final @NonNull String joinToString(
