Use of getInt() method of ByteBuffer class in java.

In this tutorial, we will see how to read integer value from byte buffer by using getInt() method of ByteBuffer class.

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 ByteBuffer	putInt(int index, byte b)	The putInt(..) method write four byte containing the given int value into associated buffer.
abstract byte	getInt()	The getInt() method read 4 byte from current position and increment position.

code


import java.nio.*;

import java.nio.ByteBuffer;

public class GetIntBuffer {

  public static final int capacity = 100;

public static void main(String[] argv) throws Exception{

    ByteBuffer bytebuf = ByteBuffer.allocate(capacity);

    bytebuf.putInt(221255);

    bytebuf.flip();

System.out.println("Integer data into byte buffer : "

        + bytebuf.getInt());

  }

}

Output

C:\>java GetIntBuffer
Integer data into byte buffer : 221255
