package com.bethecoder.tutorials.commons_lang.tests.arrays;

import org.apache.commons.lang3.ArrayUtils;

public class IsEmptyTest {

  /**
   @param args
   */
  public static void main(String[] args) {

    int [] ints = 1234567};
    int [] ints2 = null;
    
    System.out.println(ArrayUtils.isEmpty(ints));
    System.out.println(ArrayUtils.isEmpty(ints2));
    System.out.println(ArrayUtils.isEmpty(new char [] {}));
  }
