Creates a view of byte buffer as a int buffer.

In this tutorial, we will see how to creates a view of byte buffer as a int buffer.

ByteBuffer API:

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

Return type	Method	Description
static ByteBuffer	allocate(int capacity)	The allocate(..)method allocate a new byte buffer.
abstract IntBuffer	asIntBuffer()	The asIntBuffer() method creates a view of byte buffer as a int buffer.
int	limit()	The limit() method returns the limit of associated buffer.
int	position()	The position() method returns the position of associated buffer.
final int	capacity()	The capacity() method returns the capacity of associated buffer.

code


import java.nio.*;

import java.nio.ByteBuffer;

import java.nio.IntBuffer;



public class AsInt{

  public static void main(String[] args) {

	ByteBuffer byteBuf = ByteBuffer.allocate(1024);

	System.out.print("\nInformation related to byte buffer :");

	System.out.printf("\nByteBuffer Limit = %4d", byteBuf.limit());

	System.out.printf("\nByteBuffer position = %2d ", byteBuf.position());

	System.out.printf("\nByteBuffer capacity = %4d%n", byteBuf.capacity());

	IntBuffer intBuf = byteBuf.asIntBuffer();

	System.out.print("Information related to Int buffer :");

	System.out.printf("\nIntBuffer Limit = %4d", intBuf.limit());

	System.out.printf("\nIntBuffer position = %2d ", intBuf.position());

	System.out.printf("\nIntBuffer capacity = %4d%n", intBuf.capacity());

  }

}

Output

C:\>java AsInt
Information related to byte buffer :
ByteBuffer Limit = 1024
ByteBuffer position = 0
ByteBuffer capacity = 1024
Information related to Int buffer :
IntBuffer Limit = 256
IntBuffer position = 0
IntBuffer capacity = 256
