// Manipulating ints in a ByteBuffer with an IntBuffer

import java.nio.*;

public class IntBufferDemo {

private static final int BSIZE = 1024;

public static void main(String[] args) {

ByteBuffer bb = ByteBuffer.allocate(BSIZE);

IntBuffer ib = bb.asIntBuffer();

// Store an array of int:

ib.put(new int[]{ 11, 42, 47, 99, 143, 811, 1016 });

// Absolute location read and write:

System.out.println(ib.get(3));

ib.put(3, 1811);

// Setting a new limit before rewinding the buffer.

ib.flip();

while(ib.hasRemaining()) {

int i = ib.get();

/* Output:
