Love the light-weight Visual Studio Code in OS X. Have always wanted the ability to write, debug and run standard java (NOT javascript) from VSC in OS X. Found the following
There is a much easier way to run Java, no configuration needed:
Ctrl+Alt+N, or press F1 and then select/type Run Code, or right click the Text Editor and then click Run Code in context menu, the code will be compiled and run, and the output will be shown in the Output Window.
