How to find the process id of a running Java process on Windows? And how to kill the process alone?

Question

I want to kill the particular Java process in Windows, like in Linux (ps -aux to get processid and then kill processid to kill the process).

Answer 1

The solution I found is very simple. Use Window's WMIC & Java's Runtime to locate & kill the process.

Part 1: You need to put some sort of identifier into your app's startup command line. E.g. something like:

String id = "com.domain.app";

Part 2: When you run your app, make sure to include the string. Let's say you start it from within Java, do the following:

Runtime.getRuntime().exec(
   "C:\...\javaw.exe -cp ... -Dwhatever=" + id + " com.domain.app.Main"
);

Part 3: To kill the process, use Window's WMIC. Just make sure you app was started containing your id from above:

Runtime.getRuntime().exec(
  "wmic process Where \"CommandLine Like '%" + id + "%'\" Call Terminate"
);

Answer 2

1. Open Git Bash
2. Type ps -ef | grep java
3. Find the pid of running jdk
4. kill -9 [pid]
