This section demonstrates how to merge the Java ArrayList
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++) {
list1.add(ar3[i]);
}
for (int i = 0; i < ar4.length; i++) {
list2.add(ar4[i]);
}
list1.addAll(list2);
System.out.println(list);
}
}
Output
33, 45, 67, 87, 34, 56, 5, 8, 9, 22, 3, 4
