In this tutorial, we will see how to create a short array with the help of 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.
short[]	array()	The array() method returns short array based on short 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 ShortBuffArray {

  public static void main(String[] arg) {

    ShortBuffer shortBuff = ShortBuffer.allocate(1024);

    shortBuff.put((short) 43);

    shortBuff.put((short) 44);

    shortBuff.put((short) 45);

    shortBuff.flip();

    System.out

    .println("Capacity of short buffer : " 

                             + shortBuff.capacity());

    System.out.println("Content in shortbuffer : ");

    while (shortBuff.hasRemaining()) {

      System.out.println(shortBuff.get() + " ");

    }

    short[] shortArray = shortBuff.array();

    int len = shortArray.length;

    System.out.println();

  System.out.println("Length of short buffer array : "

                                              + len);

	System.out.println("Content in short buffer array : ");

    for (int i = 0; i < shortBuff.limit(); i++) {

      System.out.println(shortArray[i] + " ");

    }

  }

}

Output

C:\>java ShortBuffArray
Capacity of short buffer : 1024
Content in shortbuffer :
43
44
45
Length of short buffer array : 1024
Content in short buffer array :
43
44
45
