【Java编程，删除list中包含“a“的元素】

public class test {

    public static void main(String[] args) {
        List list = new ArrayList<>();
        list.add("asdwae");
        list.add("vvfddc");
        list.add("artrhtt");
        list.add("qwerqw");
        list.add("zxcxc");
        list.add("bnbnnb");

        System.out.println(list);
		//方法一
        Iterator iterator = list.iterator();
        for (list.iterator(); iterator.hasNext(); ) {
            String str = iterator.next();
            if (str.contains("a")) {
                iterator.remove();
            }
        }
		//方法二
        List list2 = list.stream().filter(x -> !x.contains("a")).collect(Collectors.toList());

        System.out.println(list);
        System.out.println(list2);
    }
}
