ShortBuffer slice() method in Java with Examples

The slice() method of java.nio.ShortBuffer Class is used to create a new short buffer whose content is a shared subsequence of this buffer’s content.
The content of the new buffer will start at this buffer’s current position. Changes to this buffer’s content will be visible in the new buffer, and vice versa; the two buffers’ position, limit, and mark values will be independent.
The new buffer’s position will be zero, its capacity and its limit will be the number of shorts remaining in this buffer, and its mark will be undefined. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.

Syntax:

public abstract ShortBuffer slice()

Return Value: This method returns the new short buffer.



Below are the examples to illustrate the slice() method:

Output:

Original ShortBuffer: [856, 961, 0, 0, 0, 0, 0, 0, 0, 0]

position: 2

capacity: 10

shared subsequance ShortBuffer: [856, 961, 0, 0, 0, 0, 0, 0, 0, 0]

position: 0

capacity: 8
