Iterable 迭代器只能迭代一次

public class IterableTest {
    
    
    public static void main(String[] args) {
        List<String> list=new ArrayList<>();
        list.add("a");
        list.add("b");
        list.add("c");
        list.add("d");
        list.add("e");
 
        Iterator<String> iterator = list.iterator();
 
        while (iterator.hasNext()) {
            String next =  iterator.next();
            System.out.println(next);
        }
        System.out.println("-------------------------------------");
        while (iterator.hasNext()) {
            String next =  iterator.next();
            System.out.println(next);
        }
 
    }
}

输出结果：

a
b
c
d
e
-------------------------------------
