How do I set environment variables from Java?

Question

Can anyone help me how I can able to set the environment variables in Java? Is it possible to set environment variables for the running processes?

Answer 1

You can use the below method to do that:

void setUpEnvironment(ProcessBuilder builder) {

    Map<String, String> env = builder.environment();

    // blah blah

}

Also, if your sub-processes are the same, then you don't need to go through this setup multiple times.

I hope this will help.
