[java] How to run a .jar in mac?

I've written a relatively simple java application. I have JDK on my PC, but I need it to run on a mac for school. The .jar runs perfectly on my PC, but I tested it on my Macintosh (which, BTW, does not have JDK installed).

Why isn't it running on mac? How can I fix this? Is fixing it even possible?

Make Executable your jar and after that double click on it on Mac OS then it works successfully.

sudo chmod +x filename.jar

Try this, I hope this works.

You don't need JDK to run Java based programs. JDK is for development which stands for Java Development Kit.

You need JRE which should be there in Mac.

Try: java -jar Myjar_file.jar

EDIT: According to this article, for Mac OS 10

The Java runtime is no longer installed automatically as part of the OS installation.

Then, you need to install JRE to your machine.
