java - java中join()中传递的参数有什么用？

Question

根据Java文档，如果t是一个Thread对象，其线程当前正在执行，

t.join(); 导致当前线程暂停执行，直到 t 的线程 终止。

那么，t.join(2000) 是什么意思？

这是否意味着当前线程在杀死thread t之前最多等待2秒，并且不会等待thread t自行终止？

Answer 1

So, what does t.join(2000) mean?

根据 documentation- Thread.html#join(long) .

Waits at most millis milliseconds for this thread to die. A timeout of 0 means to wait forever.

还有

Does it mean that the current thread would wait for a maximum of 2 seconds before killing thread t and wouldn't wait for thread t to terminate by itself?

它将等待死亡，但不会杀死它正在等待的威胁。
