我尝试了什么：



i尝试了所有内容，我在代码末尾写了它们但没有和我一起工作

What I have tried:

i tried everything and i wrote them at the end of the code but non worked with me

推荐答案

您应该学习尽快使用调试器。而不是猜测你的代码在做什么，现在是时候看到你的代码执行并确保它完成你期望的。



调试器允许你跟踪执行逐行检查变量，你会看到它有一个停止做你期望的点。

首先，在第一行执行断点并检查变量是否符合您的预期。然后逐行执行。

很奇怪，你的代码包含了你在转向线程之前应该掌握的很多基本错误。

You should learn to use the debugger as soon as possible. Rather than guessing what your code is doing, It is time to see your code executing and ensuring that it does what you expect.

The debugger allow you to follow the execution line by line, inspect variables and you will see that there is a point where it stop doing what you expect.

In first, put a breakpoint on very first line executed and check that variables meet your expectations. Then executed line by line.
Weird, your code contain very basic mistakes on things that you should have mastered long before turning to threads.
