Create a duplicate short buffer that shares the content of a short buffer.

In this tutorial, we will see how to create a duplicate short buffer that shares the content of a short buffer.

ShortBuffer API:

The java.nio.ShortBuffer class extends java.nio.Buffer class. It provides the following methods:

Return type Method Description
static ShortBuffer allocate( int capacity)  The allocate(..) method allocate a short buffer of given capacity. 
abstract ShortBuffer duplicate() The duplicate() method returns a  duplicate buffer that share the content of available buffer.
abstract short get() The get() method read short value from current position and increment position..

Code

import java.nio.*;
import java.nio.ShortBuffer;

public class DShortBuffer {
public static void main(String[] arg) {
    ShortBuffer shortBuff = ShortBuffer.allocate(1024);
    shortBuff.put((short) 566);
    shortBuff.put((short) 878);
    shortBuff.put((short) 4886);
    shortBuff.flip();
System.out.println("Capacity of original short buffer : "
        + shortBuff.capacity());
System.out.println("Content in original short buffer : ");
    while (shortBuff.hasRemaining()) {
      System.out.print(shortBuff.get() + " ");
    }
    System.out.println();
    ShortBuffer dBuffer = shortBuff.duplicate();
    int capacity = dBuffer.capacity();
    dBuffer.flip();
System.out.println("Capacity of duplicate short buffer :"
     + capacity);
System.out.println("Content in duplicate short buffer : ");
    for (int i = 0; i < dBuffer.limit(); i++) {
      System.out.print(dBuffer.get() + " ");
    }
  }
}

Output

C:\>java DShortBuffer
Capacity of original short buffer : 1024
Content in original short buffer :
566 878 4886
Capacity of duplicate short buffer :1024
Content in duplicate short buffer :
566 878 4886
