Code

import java.nio.*;
import java.nio.IntBuffer;
public class IntBufferArray {
  public static void main(String[] argsthrows 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]);
    }
  }
