ShortBuffer equals() method in Java

The equality of two buffers can be checked using the method equals() in the class java.nio.ShortBuffer. Two buffers are equal if they have the same type of elements, the same number of elements and same sequence of elements. The method equals() returns true if the buffers are equal 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 buffer1 = ShortBuffer.allocate(n);
         buffer1.put((short)12);
         buffer1.put((short)91);
         buffer1.put((short)25);
         buffer1.put((short)18);
         buffer1.put((short)30);
         buffer1.rewind();
         System.out.println("The first ShortBuffer is: " + Arrays.toString(buffer1.array()));
         ShortBuffer buffer2 = ShortBuffer.allocate(n);
         buffer2.put((short)12);
         buffer2.put((short)91);
         buffer2.put((short)25);
         buffer2.put((short)18);
         buffer2.put((short)30);
         buffer2.rewind();
         System.out.println("The second ShortBuffer is: " + Arrays.toString(buffer2.array()));
         boolean flag = buffer1.equals(buffer2);
         if (flag)
            System.out.println("\nBoth the buffers are equal");
         else
            System.out.println("\nBoth the buffers are not equal");
      } 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 −

Output

The first ShortBuffer is: [12, 91, 25, 18, 30]
The second ShortBuffer is: [12, 91, 25, 18, 30]

Both the buffers are equal
