Compare buffer to another object.

In this tutorial you will see how to compare buffer to another object. The compareTo method of CharBuffer class allow to compare buffer with another. This method returns 0, 1 or -1 which means it is equal, less and greater than the comparing buffer.  

Code:

import java.nio.CharBuffer;

public class CharBufferDemo {
  public static void main(String[] args) {
    char[] chr = new char[] { 'a''b''c''d''e' };
    CharBuffer charbuffer1 = CharBuffer.allocate(10);
    charbuffer1.put(chr);

    char[] chr1 = new char[] { 'a''b''c''d''e' };
    CharBuffer charbuffer2 = CharBuffer.allocate(10);
    charbuffer2.put(chr1);
    System.out.println(charbuffer2.compareTo(charbuffer1));

    char[] chr2 = new char[] { 'a''b''c''d''e''f' };
    CharBuffer charbuffer3 = CharBuffer.allocate(10);
    charbuffer3.put(chr2);
    System.out.println(charbuffer3.compareTo(charbuffer1));

    char[] chr3 = new char[] { 'a''b''c''d' };
    CharBuffer charbuffer4 = CharBuffer.allocate(10);
    charbuffer4.put(chr3);
    System.out.println(charbuffer4.compareTo(charbuffer1));
  }
}
