Apache Commons Lang 3.0 is a java library with lot of utilities and reusable components. This requires the library commons-lang3-3.0.1.jar to be in classpath. The following example shows using ArrayUtils.addAll() API.
package com.bethecoder.tutorials.commons_lang.tests.arrays; import org.apache.commons.lang3.ArrayUtils; public class AddAllTest { /** * @param args */ public static void main(String[] args) { int [] ints = { 1, 2, 3, 4 }; int [] ints2 = new int[4]; int [] ints3 = { 8, 9 }; ints = ArrayUtils.addAll(ints, 5, 6, 7, 8); System.out.println(ArrayUtils.toString(ints)); ints2 = ArrayUtils.addAll(ints2, 5, 6); System.out.println(ArrayUtils.toString(ints2)); int [] ints4 = ArrayUtils.addAll(ints2, ints3); System.out.println(ArrayUtils.toString(ints4)); } }
{1,2,3,4,5,6,7,8} {0,0,0,0,5,6} {0,0,0,0,5,6,8,9}
