In this tutorial, we will see how to create a int array with the help of int buffer.

IntBuffer API:

The java.nio.lntBuffer 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 int buffer of given capacity.
float[]	array()	The array() method returns int array based on int buffer.
int	get()	The get() method read int value from current position and increment position..

Code


import java.nio.*;

import java.nio.IntBuffer;

public class IntBufferArray {

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

    IntBuffer intBuffer = IntBuffer.allocate(234);

    intBuffer.put(23);

    intBuffer.put(24);

    intBuffer.flip();

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

    while (intBuffer.hasRemaining()) {

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

    }

    int[] array = intBuffer.array();

	System.out.println("Int value in array which provided by int buffer.");

    for (int i = 0; i < intBuffer.limit(); i++) {

      System.out.println(array[i]);

    }

  }

}

Output

C:\>java IntBufferArray
Int value in buffer.
23
24
Int value in array which provided by int buffer.
