ShortBuffer hasArray() method in Java

It can be checked if a buffer has the backing of an accessible short array by using the method hasArray() in the class java.nio.ShortBuffer. This method returns true if the buffer has the backing of an accessible double array and false otherwise.

A program that demonstrates this is given as follows −

Example

 Live Demo

import java.nio.*;
import java.util.*;
public class Demo {
   public static void main(String[] args) {
      int n = 5;
      try {
         ShortBuffer buffer = ShortBuffer.allocate(5);
         buffer.put((short)12);
         buffer.put((short)91);
         buffer.put((short)25);
         buffer.put((short)18);
         buffer.put((short)30);
         buffer.rewind();
         System.out.println("The ShortBuffer is: " + Arrays.toString(buffer.array()));
         boolean flag = buffer.hasArray();
         if (flag)
            System.out.println("The ShortBuffer is backed by an array");
         else
            System.out.println("The ShortBuffer is not backed by any array");
      } catch (IllegalArgumentException e) {
         System.out.println("Error!!! IllegalArgumentException");
      } catch (ReadOnlyBufferException e) {
         System.out.println("Error!!! ReadOnlyBufferException");
      }
   }
}

Output

The ShortBuffer is: [12, 91, 25, 18, 30]
The ShortBuffer is backed by an array
