    Default How do I use a class inside a library?

    I have a class inside my projects library called 'customSwingControls.jar', the class I want to use is 'ProjectName/Libraries/CustomSwingControls.jar/Classes/customButton.class'. I want to use customButton.class as a type inside a parameter but I'm not sure how to properly do this (I don't know how to import the class).

    private void makeMove(customButton button){
    //code here
    }

    When I do this I receive an error over 'customButton' that says 'cannot find symbol'.

    The jar file needs to be on the classpath
    and the code needs to import the package the class is in.
    If you don't understand my answer, don't ignore it, ask a question.
