    Re: Array help

    What type is a? Is it the float array that belongs to FloatList? Java arrays are objects. I could be wrong, but I don't think they have an append() method. Could you provide the actual error...

    Re: Array help

    Primitives are simple data types, built into to Java language, and just hold a particular kind of value - they don't have methods. You can read about all of the primitives here. So, "float" is a...

    What I am trying to get you to do is show me how you expect your class to work, as well as how it is working now. Without being able to do this, how do you know if your code is right or wrong?

  8. Re: Custom Java stack class (with generics) problem
