Compiling/Running Program
已回答
I can't find the button to run my Java program, I watched some videos and I can't seem to find the run button on the left and I can't find the run button in green(is shaded out) on the top right either.

Hi Ethan,
In order for stuff like running your code, error highlighting, etc. to work in Java files, you need to put them into a Sources directory (blue folder icon). You can mark a directory as such by right-clicking on it in the Project view on the left, and selecting 'Mark directory as' > 'Sources Root'.
See example below.
Thank You, I couldn't put a Java Class file into the src folder even though I saw that I should in some tutorials re-installing it worked.
