Java equivalent to php die
提问by Lamis
I've done some research to know if there is an equivalent to PHP die in java
我已经做了一些研究，想知道在 Java 中是否有相当于 PHP die 的东西
Sometimes I'm doing small tests and I really want to stop my code at specific line , and return doesnt stop the code like "die" in php
有时我在做一些小测试，我真的想在特定行停止我的代码，并且 return 不会停止像 php 中的“死”这样的代码
Is there a die quivalent in java?

Disclaimer: I'm not that familiar with Java, I have a basic working knowledge of it, but haven't done a huge amount of work with it.
免责声明：我对 Java 不太熟悉，我对它有基本的工作知识，但还没有做过大量的工作。
I suppose you could just throw() an exception and not catch it, that should halt execution. Of course if you have an exception handler for exceptions that aren't caught locally you might have problems.
我想你可以只 throw() 一个异常而不捕捉它，这应该停止执行。当然，如果您有一个用于本地未捕获的异常的异常处理程序，您可能会遇到问题。
Most IDEs let you set breakpoints where execution will stop and you'll be able to examine the state of variables, look at the call stack and so on. Both Eclipse and Netbeans support this. It might be a better option.
大多数 IDE 允许您设置执行将停止的断点，您将能够检查变量的状态，查看调用堆栈等。Eclipse 和 Netbeans 都支持这一点。这可能是一个更好的选择。
EDIT: There is also System.exit() which will halt execution. I still think breakpoints are a better option though.
编辑：还有 System.exit() 将停止执行。我仍然认为断点是更好的选择。
