List的遍历

public class Main {
    public static void main(String a[]) {
        List<String> list  = new ArrayList<>();
        list.add("zhang");
        list.add("wang");
        list.add("li");
        list.add("chen");
        list.add("lin");
        
        //1.迭代器遍历，需要用到Iterator
        System.out.println("迭代器遍历");
        Iterator<String> it = list.iterator();
        while (it.hasNext()) {
            System.out.printf(it.next()+"  ");
        }
        System.out.println();
        
          //2. 普通for遍历,借用size()方法
        System.out.println("普通for遍历");
        for (int i = 0; i < list.size(); i++) {
            System.out.printf(list.get(i)+"  ");
        }
        System.out.println();
        
        //3.增强for，也就是foreach
        System.out.println("增强for遍历");
        for (String string : list) {
            System.out.printf(string+"  ");
        }
        System.out.println();
        
        //4.lamda遍历，利用List的forEach
        System.out.println("Lamda遍历");
        list.forEach(s->System.out.printf(s+"  "));
        System.out.println();
        
        //5.列表迭代器
        System.out.println("列表迭代器遍历");
        ListIterator<String> lit = list.listIterator();
        while(lit.hasNext()) {
            System.out.printf(lit.next()+"  ");
        }
    }
}
