CharBuffer equals() method in Java

The equality of two buffers can be checked using the method equals() in the class java.nio.CharBuffer. Two buffers are equal if they have the same type of elements, the same number of elements and the 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 −


 Live Demo

import java.nio.*;
import java.util.*;
public class Demo {
   public static void main(String[] args) {
      int n = 5;
      try {
         CharBuffer buffer1 = CharBuffer.allocate(n);
         System.out.println("The first CharBuffer is: " + Arrays.toString(buffer1.array()));
         CharBuffer buffer2 = CharBuffer.allocate(n);
         System.out.println("The second CharBuffer is: " + Arrays.toString(buffer2.array()));
         boolean flag = buffer1.equals(buffer2);
         if (flag)
Both the buffers are equal");          else             System.out.println("
Both the buffers are not equal");       } catch (IllegalArgumentException e) {          System.out.println("Error!!! IllegalArgumentException");       } catch (ReadOnlyBufferException e){          System.out.println("Error!!! ReadOnlyBufferException");       }    } }


The first CharBuffer is: [A, P, P, L, E]
The second CharBuffer is: [A, P, P, L, E]
Both the buffers are equal
