For the newer versions of Intellij, press Ctrl + Alt + Shift + s to open project settings, then choose Modules, under Dependencies tab choose the green + and add the folder in which your . class file is located. Under scope, choose compile.
I have two IntelliJ IDEA Java projects; ProjectA and ProjectB. I want to import and use code from ProjectA in ProjectB. How do I do this?
In Eclipse I would simply go to ProjectB's Build Path settings and add ProjectA.
