Check for any elements exists between the current position and the limit of a buffer.

In this tutorial you will see how to check for existence of any element between the current position and the limit of a buffer. The hasRemaining method returns true when there exists atleast one element in the buffer and returns false when there is no element available in the buffer.

Code:


import java.nio.CharBuffer;



public class CharBufferDemo {

  public static void main(String[] args) {

    char[] chr = new char[] {};

    CharBuffer charbuffer1 = CharBuffer.wrap(chr);

    charbuffer1.put(chr);

    System.out.println(charbuffer1.hasRemaining());

    char[] chr1 = new char[] { 'a' };

    CharBuffer charbuffer2 = CharBuffer.wrap(chr1);

    charbuffer2.put(chr);

    System.out.println(charbuffer2.hasRemaining());

  }

}

Output:

False
True
