I want to ?reduce? the CPU usage/ROM usage/RAM usage - generally?, all system resources that my app uses - who doesn't? :)
For this reason I want to split the preferences window from the rest of the application, and let the preferences window to run as ?independent? program.
The preferences program ?should? write to a Property file(not a problem at all) and to send a "update signal" to the main program - which means it should call the update method (that i wrote) that found in the Main class.
How can I call the update method in the Main program from the preferences program?
To put it another way, is a way to build preferences window that take system resources just when the window appears?
Is this approach - of separating programs and let them talk to each other (somehow) - the right approach for speeding up my programs?
