ShortBuffer duplicate() method in Java

A duplicate buffer of a buffer can be created using the method duplicate() in the class java.nio.ShortBuffer. This duplicate buffer is identical to the original buffer. The method duplicate() returns the duplicate buffer that was created.

A program that demonstrates this is given as follows −


 Live Demo

import java.nio.*;
import java.util.*;
public class Demo {
   public static void main(String[] args) {
      int n = 5;
      try {
         ShortBuffer buffer1 = ShortBuffer.allocate(5);
         System.out.println("The Original ShortBuffer is: " + Arrays.toString(buffer1.array()));
         ShortBuffer buffer2 = buffer1.duplicate();
         System.out.print("The Duplicate ShortBuffer is: " + Arrays.toString(buffer2.array()));
      } catch (IllegalArgumentException e){
         System.out.println("Error!!! IllegalArgumentException");
      } catch (ReadOnlyBufferException e) {
         System.out.println("Error!!! ReadOnlyBufferException");

The output of the above program is as follows −


The Original ShortBuffer is: [12, 91, 25, 18, 30]
The Duplicate ShortBuffer is: [12, 91, 25, 18, 30]
