How to make a .jar file executable by clicking?

edit

Hi, so my question is how do I make a .jar program executable by left click/double click. For example I have programs in my Downloads folder i.e. "program.jar". I've been running these kinds of programs by executing the following code "java -jar /path/to/file/program.jar" in the terminal. How can I make the "program.jar" executable by clicking it?
