Java arraylist merge

This section demonstrates how to merge the Java ArrayList

  • In Java Two arrays can be joined by using the Collection list.
  • Add all the elements of the both arrays into the list1, list2 respectively.
  • Use addAll() method to add list2 into the list1. Now the list2 is joined in to the list1.

Example Java Arraylist Merge
import java.util.*;
public class array3 {
    public static void main(String[] args) {
        int ar3[]={33,45,67,87,34,56};
        int ar4[]={5,8,9,22,3,4};
        List list1=new ArrayList();
        List list2=new ArrayList();
         for (int i = 0; i < ar3.length; i++) {
   for (int i = 0; i < ar4.length; i++) {
33, 45, 67, 87, 34, 56, 5, 8, 9, 22, 3, 4
