how to specify value of a Java variable at runtime?

Answer 1

The 'main' method accepts a String array that you can use to pass command line options. It's pretty straightforward to parse the array and a very easy option.

Alternatively, you can have an environment variable set and check it through System.getenv(), but this is a little more complicated as many users aren't familiar with setting environment variables anymore.
