import java.nio.ShortBuffer;
public class PutValueAtIndex {
  public static final int index=2;
  public static void main(String[] arg) {
short[] array = new short[] { 1, 2, 3, 4, 5 };
ShortBuffer shortBuf = ShortBuffer.wrap(array);
System.out.println("Content in short buffer.");
    while (shortBuf.hasRemaining())
    {
    System.out.print(shortBuf.get()+" ");    
    }
    System.out.println();
System.out.println("Put value at index . "
                                      +index);
System.out.println("Content in short buffer.");
    shortBuf.put(2, (short) 655);
    shortBuf.flip();
    while (shortBuf.hasRemaining())
    {
    System.out.print(shortBuf.get()+" ");  
    }
