Java中的break、continue 到底返回什么

break;

作用：跳出当层循环，如果当层循环已经是最外一层则直接退出循环

测试代码

        for (int j = 0; j < 3; j++) {
          System.out.println("j = " + j);
            for (int i = 0; i < 10; i++) {
                if (i < 2) {
                    System.out.println("i = " + i);
                }else {
                    System.out.println("execute break...");
                    break;
                }
            }
        }

执行结果

j = 0
i = 0
i = 1
execute break...
j = 1
i = 0
i = 1
execute break...
j = 2
i = 0
i = 1
execute break...

continue;

作用：结束当次循环剩下的部分，继续本层循环

测试代码

           for (int i = 0; i < 10; i++) {
                if (i % 2 == 0) {
                    continue;
                } else {
                    System.out.println(i);
                }
            }

执行结果
