    i think you have to read about object-oriented languages like Java.
    here are a few references:

    sitepoint.com/article/oriented-concepts-java-1/

    I suggest following Wolfcro's advice. The class concept is *fundamental* to Java.

    Default Closer to the real world...

    Yes... the links that wolfcro supplied will help you understand better the OOP concepts. A very simple way to explain OOP is a way to help to program to the real world (classes, objects, etc) that surrounds us (at least that's how I see it).

    Actually, I think it is very simple if you are just beginning.

    There are 2 types of classes, a class with constructors and methods and a testing class with a main.

    Here is how you write them

    public class Example{
    Constructors;
    Methods();
    {

    public class ExampleTester {
    public static void main(String[] args) {

    Here you test the methods from the other class. This is the main class...you always HAVE to have this in any program.
    }
    }

    simplest answer is that you have to use classes.

    and you can just as easily put a main method in the actual class without having to create one just for testing purposes. i don't know why it seems to be so popular to do this.

    It's popular because if you have a BIG program with ALOT of methods, ect. it is much easier to refer back to that and much more organized to have 2 classes.

    It not necessarly easier, it's just more organized.

    So you don't have to scroll all the way up your main class and you other classes to determine which methods/constructors you have.

    It is more organized to create a seperate class for those.

    seems like your opinion is based on your experience writing code and what editor you're using, which goes into a larger argument in the sticky. let's just agree to disagree =p

    haha I guess your right.

    BTW I use eclipse for all my coding and I just started so I don't have much experience. Just a guy who listens to what my teacher says
