  • Are you referring to threads when you speak of "running application in my java code"? Please edit your question and enhance your question so that it is understandable what you want to to and what you already tried. – Robert Aug 19 '14 at 09:14

You could try to open a specific file and lock it when your program starts. If another instance of the program starts and tries to lock the file, it will throw an exception. Here is an example of locking a file in Java.
