对于ArrayList的几种遍历方法

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

public class ListDemo1 {
    public static void main(String[] args) {
        List<String> lists=new ArrayList<>();
        lists.add("java1");
        lists.add("java2");
        lists.add("java3");
        /*
        * for循环遍历
        * */
        System.out.println("--------------------");
        for (int i = 0; i < lists.size(); i++) {
            String ele=lists.get(i);
            System.out.println(ele);
        }

        /*
        * 迭代器遍历
        * */
        System.out.println("---------------");
        Iterator<String> it=lists.iterator();
        while (it.hasNext()){
            String ele= it.next();
            System.out.println(ele);
        }
    /*
    * foreach
    * */
        System.out.println("---------------");
        for (String ele:lists){
            System.out.println(ele);
        }
    }
}
