get the name of a runnable jar file

Question

Hello so I have made an Jar updater and it is working perfect the only issue i am having is that if the client is named different it will download it as a separate jar file and not replace the one you are running so this is where i get my client location and name

private static String myClient = System.getProperty("user.dir") + File.separator  + "Trinity.jar";

Now i was wondering how do i get the name of the jar that has been ran on startup so i can use it to replace the old jar file correctly

Java provides MyClass which contains all the attributes of the current class's context which includes runtime information. Using the right combination utility functions can yield you the required path.

Path = MyClass.class.getProtectionDomain().getCodeSource().getLocation().toURI().getPath();
