Get the path of a running jar file

When code is running inside a jar file, say foo.jar, and we need to know, in the code, in which folder the running foo.jar is use this command in the Java code.

 return new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation().getPath());

Another of achieving the same is using the following code:

String path = Test.class.getProtectionDomain().getCodeSource().getLocation().getPath();
String decodedPath = URLDecoder.decode(path, "UTF-8");
