Can somebody explain why you need this jar File? It appears as the class and the jar file have the same functionality, so why do we need to create a jar file? Thanks

@DreamDropsTV 3 жыл бұрын

Jar file can be used to make an executable application which you can click and run on any OS(since java is platform independent, but keep it in mind target machine must have JRE installed) JAR is also used to archive certain class files and store it in a repository for future use (As normally people use winRAR, winZip, 7zip) JAR is also an file archiver

@TrishaGee 4 жыл бұрын

There used to be two keymaps for the Mac. The old one is more similar to the Windows shortcuts, so maybe that's the one you're using? The keymap I'm using (the one from the video) used to be called "Mac OS X 10.5", although I think in the latest version of IntelliJ IDEA it's just the default MacOS keymap.
