    I am new to java and learning. How do I write an application to calculate the area of a Triangle, where the area calculation is performed in a Triangle class not in the App class. Am at a loss with this one and what it means.
    Am using notepad++ .

    College project?
    A quick google reveals loads of info on this.
    Maybe post your code so far.

    If you're struggling with the maths have a look at this followed by this.

    Not a college project. Learning Java and am struggling. Maths part I am okay with but differentiating between app class and triangle class and writing the correct code for this.

    Well first write the app with just an App class. Copy a "hello world" bog-standard program for this. Instead of printing hello world, calculate the area and print that instead.

    That's step 1. Do that before you try to do a Triangle class.

    That's a coincidence. I had the exact same Java problem due for submission last Friday evening. :D

    I can't guess who you are from your Boards username but feel free to give me a shout as I wrote an intermediate command line version of the program which leaves out all the library code for the GUI windows so it's easier to see how the App() method interacts with the Triangle object.

    My Boards user name is simply the first 3 letters of my real name so now you know who I am.

    If the OP is a student looking for an easy solution to a project then don't give them the source code. Let them learn how to do it! Otherwise, what's the point in a course exercise?

    I'd recommend just get it working inside the Main method first and then once you have this working you can look at moving it to a seperate class.
