Java Iterating through a List

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

public class Collection3 {

public static void main(String[] args) {
    Below is the Collectiion using List

    List<String> lists = new ArrayList<String>();
                 lists.add("Cainton Milroy");
                 lists.add("Jerima Milroy");
                 lists.add("Kenzilla Milroy");

The habitual way of iterating in Java Loops, but not desirable way of iterating and printing each of the elements

for(int i = 0; i < lists.size();i++){
    System.out.println(lists.get(i));
}

The Java good way of iterating through a loops than the traditional way of iterating through a loop

                 for(String element : lists){
                     System.out.println("Elements : "+ element);
                 }

                 System.out.println("_-_-_-_-_Second For Loop-_-_-_-_-_-_-_-");

                 Iterator<String> itr = lists.iterator();

                 while(itr.hasNext()){
                     String element = itr.next();
                     System.out.println("Element: " + element);
                 }

                 System.out.println("_-_-_-_-Lambda Expression_-_-_-_-_-_-_-_-");
                 lists.forEach((final String name) -> System.out.println(name));
}
