Java I/O How to - Compare two CharBuffer for Equality

Question

We would like to know how to compare two CharBuffer for Equality.

Answer

import java.nio.CharBuffer;
// www .  j  a v a  2s  .c  o  m
public class MainClass {
  public static void main(String[] args) {
    CharBuffer cb1 = CharBuffer.allocate(5), cb2 = CharBuffer.allocate(5);
    cb1.put('B').put('u').put('f').put('f').put('A');
    cb2.put('B').put('u').put('f').put('f').put('B');
    cb1.rewind();
    cb2.rewind();
    System.out.println(cb1.limit(4).equals(cb2.limit(4)));
  }
}

The code above generates the following result.
