Java Return不退出方法(循环) [英] Java Return not exiting method (loops)

问题描述

我正在为一个学校的项目工作，该方法的方法中有许多嵌套循环.我可以验证我的代码是否达到返回真值"；在返回假"之前的陈述；使用太多System.out.println语句.

I'm working on a project for school where I have many nested loops in a method. I can verify that my code is reaching the "return true;" statement before a "return false;" using way too many System.out.println statements.

在任何情况下return不会立即退出该方法.在我的代码中，它达到了return true;"，但随后继续执行该方法.

Is there any case where return does not immediately exit the method. In my code it reaches the "return true;", but then continues working through the method.

谢谢-第一次发帖，但长期学习其他问题的学生

Thanks - first post, but long time student from other questions

显示我的代码-这是针对UC Berkeley项目的，因此他们不允许我们发布完整的代码.这是重要的部分.

Show my code - This is for a UC Berkeley project so they aren't allowing us to post our full code. Here is the important parts.

我的代码中没有"try语句".这是我的方法的结尾，它具有大量的循环(而& for)循环.

There are no "try statements" in my code. This is the very end of my method which has a ton of loops (while & for) loops.

if (x == 7 && turn == 5){
                    System.out.println("TRUE RESULT");
                    return true;


                }

                nextVictory(turn, x, y, color,z);
                alive = false;
            }

        }


          }
    }
    System.out.println("FALSE RESULT");
    return false;
}

我有打印声明以确认我在哪里.结果如下:

I have print statement to verify where I'm at. Here are the results:

推荐答案

在任何情况下return不会立即退出该方法吗?

Is there any case where return does not immediately exit the method?

唯一想到的情况是 return 语句是否在 try - finally 块内. finally 块仍将执行.

The only case that comes to mind is if the return statement were inside a try-finally block. The finally block would still get executed.

另一种可能表现出类似行为的情况是，如果您的方法是递归的.在这种情况下，嵌套调用中的 return 语句实际上会返回给调用者.但是，如果调用者是方法本身，则该方法的外观可能会继续通过 return 返回执行.

Another case that could exhibit similar behaviour is if your method is recursive. In that case, a return statement in a nested call would actually return to the caller. However, if the caller is the method itself, this could have the appearance of the method continuing to execute past the return.
