放段代码，自己反思

private static List
   
     list = new ArrayList<>();    static {
               list.add(1);            list.add(2);            list.add(3);            list.add(4);            list.add(5);            list.add(6);    }    public static void main(String[] args){
           breakTest();        returnTest();        continueTest();    }    public static void breakTest(){
           System.out.println("breakTest start");         for (Integer i :list){
                if (i==4){
                    break;             }             System.out.println(i);         }        System.out.println("breakTest end");    }    public static void returnTest(){
           System.out.println("returnTest start");        for (Integer i :list){
                if (i==4){
                    return;             }             System.out.println(i);         }        System.out.println("returnTest end");    }    public static void continueTest(){
           System.out.println("continueTest start");        for (Integer i :list){
                if (i==4){
                    continue;             }             System.out.println(i);         }        System.out.println("continueTest end");    }
   

输出结果：

breakTest start

returnTest start

continueTest start
