I'm not a java expert or a eclipse expert. Currently I'm working on a project and i need to debug/test often. I use the eclipse run Button for it. But when I don't close the Program eclipse/java opens it again(second window). It's an gui app with swing jframe.

Is there a function in eclipse or java to terminate the previous build and opens the new one when you run it?
