Check for number of 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 remaining method returns the number of element available in a 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.remaining());

    char[] chr1 = new char[] { 'a' 
	, 'b' };

    CharBuffer charbuffer2 = CharBuffer.wrap(chr1);

    charbuffer2.put(chr);

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

  }

}

Output:
