ShortBuffer compareTo() method in Java

Java 8Object Oriented ProgrammingProgramming

A buffer can be compared with another buffer using the method compareTo() in the class java.nio.ShortBuffer. This method returns a negative integer if the buffer is less than the given buffer, zero if the buffer is equal to the given buffer and a positive integer if the buffer is greater than the given buffer.

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()));
         int val = buffer1.compareTo(buffer2);
         if (val == 0)
            System.out.println("
Both the buffers are lexicographically equal"); else if (val > 0) System.out.println("
The first buffer is lexicographically greater than the second buffer"); else System.out.println("
The second buffer is lexicographically greater than the first buffer"); } catch (IllegalArgumentException e) { System.out.println("Error!!! IllegalArgumentException"); } catch (ReadOnlyBufferException e) { System.out.println("Error!!! ReadOnlyBufferException"); } } }

Output

The first ShortBuffer is: [12, 91, 25, 18, 30]
The second ShortBuffer is: [12, 91, 25, 18, 30]
Both the buffers are lexicographically equal
