In this tutorial, we will see how to transfer the content of a int buffer into another int buffer.

IntBufferAPI:

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 allocate a new int buffer.
IntBuffer	put(IntBuffer buffer)	The put(..)method transfer the content of a int buffer into another int buffer.

Code


import java.nio.*;

import java.nio.ByteBuffer;

import java.nio.IntBuffer;



public class BufferToBuffer {

public static void main(String[] arg){

ByteBuffer b = ByteBuffer.allocateDirect(512);

    IntBuffer oldBuffer = b.asIntBuffer();

    int[] array = new int[] { 2, 3, 4, 5 };

    for (int s = 0; s < array.length; s++) {

      oldBuffer.put(array[s]);

    }

    oldBuffer.flip();

  IntBuffer newBuffer=IntBuffer.allocate(521);

    newBuffer.put(oldBuffer);

    newBuffer.flip();

System.out.println("Int value in new buffer.");

    while (newBuffer.hasRemaining()) {

      System.out.println(newBuffer.get());

    }

  }

}

Output

C:>java BufferToBuffer
Int value in new buffer.
