• Elements of the ArrayList can be easily added and retrieved by the for loop.

import java.util.ArrayList;
import java.util.List;

public class List_for {
    public static void main(String[] args) {
        List list=new ArrayList();
        String names[]={"mac","john","alexender","rock","alex"};
        for (int i = 0; i < names.length; i++) {
        list.add(names[i]);
        }
        for (int i = 0; i < names.length; i++) {
        System.out.println((i+1)+" : "+list.get(i));
        }
    }
}
Output
1 : mac
2 : john
3 : alexender
4 : rock
