When I run Java from a batch file, can I hook a batch file to force exit?

Question

I create a directory in a Java file and delete it when done.

If I quit during Java work, of course it will not perform the deletion.

I've used addShutdownHook() but it seems to work fine with a shutdown command.

My forced shutdown means when i closing the running batch file window. (:when push X button)

Is there a way to solve it in Java source?

It is my tried source

.
.
.
Runtime.getRuntime().addShutdownHook(new Thread() {
                @Override
                public void run() {
                    // TODO Auto-generated method stub
                    FileUtils.deleteQuietly(new File(basePath));
                }
            });
.
.
.

Please see https://stackoverflow.com/questions/12404712/java-shutdown-hook-not-run?rq=1 and take a look at the answer of Nilesh Jadav. Shutdown Hooks are not guaranteed to be executed. — Korashen, Sep 18 '18 at 08:45
It sounds like you want to avoid the cmd window when you run java. https://stackoverflow.com/questions/15605467/start-apache-in-background-with-batch-file When you ask the os to kill a process, it does it with varying degrees of severity. If the window isn't present, then it is easier to not close the cmd prompt window. — matt, Sep 18 '18 at 09:06

I can not think of a pure java solution. The problem is, if your program is forced to shutdown, e.g. with kill -9 (SIGKILL), there is no chance for your program to hook in between. It will shutdown immediately.

You could use monitoring tools like monit or deamontools or supervisord to perform clean-up operations as soon as your program has been shutdown.

You can also provide a handmade solution like suggested here: Shell Script For Process Monitoring , e.g. using tools like watch.
