I felt like learning some foreign languages, and I found just the software to help me out. Learning with Texts sounded fascinating at first glance, so I unzipped the file and out came a java file.

After realizing that .jar files cannot be executable but only be run in the VM, I do a right click on the file and I click on Oracle Java 7 Runtime to run it. The problem is that I want it to be default but I can't. I looked at properties and a list of programs I can use. None of them showed Oracle Java 7 Runtime.

How can I allow Oracle Java 7 Runtime to work with a double click? How can I compile this to allow it to run straight from the command line?
