Calculate total number of elements remaining in the buffer.

In this tutorial, we will discuss how to calculate total number of elements remaining in the buffer.

IntBuffer API:

The java.nio.IntBuffer class extends java.nio.Buffer class. It provides the following methods:

Return type	Method	Description
static IntBuffer	allocate( int capacity)	The allocate() method create a int buffer of specified capacity.
int	get()	The get() method read int value from current position of int buffer.

Buffer API:

The java.nio.Buffer class extends java.lang.Object class. It provides the following methods:

Return type	Method	Description
Int	remaining()	The remaining() method returns remaining element in buffer.

Code


import java.nio.*;

import java.nio.IntBuffer;



public class RemainElement {

  public static void main(String[] arg) {

    IntBuffer intBuffer = IntBuffer.allocate(256);

    intBuffer.put(22);

    intBuffer.put(23);

    intBuffer.put(24);

    intBuffer.flip();

    System.out

	.println("Current position of buffer:" + intBuffer.position());

	System.out.println("Current limit of buffer:" + intBuffer.limit());

    int i = intBuffer.remaining();

    System.out

    .println("Number 
	of remaining elements in buffer : " + i);

  }

}

Output

C:\>java RemainElement
Current position of buffer:0
Current limit of buffer:3
Number of remaining elements in buffer : 3
