Java，运行外部程序

Question

I am trying to write a chatbot. I am still in my startings, but I do have one question.

Process proc = Runtime.getRuntime().exec("notepad.exe");

This actually makes it impossible to quit my program, unless I quit the notepad. Is it possible to quit the Java program before this notepad has ended?

Answer 1

您可以通过程序中的单独线程运行外部程序，并在主线程中继续执行程序逻辑，即， 多线程应用程序是一个很好的解决方案。

Answer 2

First destroy the subprocess :

Process proc = Runtime.getRuntime().exec("notepad.exe");
proc.destroy();

If this doesn't work, get the process id of the process and run a different subprocess to run kill <pid>

then exit java with System.exit(0); or normally.
