What does the class mean?

A class is essentially an object that you can create in your programs for however many of those objects you need. For instance, you could have a class called Apple. Inside the apple class, you would have its color, size, juiciness, etc. Then in your main program, say you wanted three different apples, you just create three different Apple variables, then define their shape, size, color etc and voila! You have three apples!
