How to create a short buffer with the help of byte buffer.

 In this tutorial, we will see how to create a short buffer with the help of byte buffer.

ByteBuffer API:

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

Return type Method Description
static ByteBuffer allocate( int capacity)  The allocate() method allocate a byte buffer of given capacity. 
 abstrtact shortBuffer  asShortBuffer() The asShortBuffer() method returns short buffer based on byte buffer.

Buffer API:

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

Return type Method Description
int limit() The limit() method returns the limit of short buffer.
final int capacity() The capacity() method returns the capacity of associated short buffer.

Code

import java.nio.*;
import java.nio.ByteBuffer;
import java.nio.ShortBuffer;
public class ShortBufferDemo1  {
  public static void main(String[] arqg) {
ByteBuffer byteBuff = ByteBuffer.allocate(1024);
ShortBuffer shortBuff = byteBuff.asShortBuffer();
    shortBuff.put((short32767);
    shortBuff.flip();
System.out.println("capacity of short buffer :"
 
                       + shortBuff.capacity());
 System.out.println("Limit of short buffer :" 
                           + shortBuff.limit
());
    while (shortBuff.hasRemaining()) {
System.out.println("Content in shortbuffer : "
 
                          + shortBuff.get());
    }
  }
}

Output

C:>java ShortBufferDemo1
capacity of short buffer :512
Limit of short buffer :1
Content in shortbuffer : 32767
