This lesson is going to use the same code from last time to explain the class
|
|
|
|
|
structure itself.

Since the example languages can have quite different styles of class
|
|
|
|
|
declaration, I will just give a basic explanation here and then discuss every
|
|
|
|
|
language in detail in their own description file.

Classes are blueprints for the objects you create. You define how the object
|
|
|
|
|
will look like and more importantly for the computer how much space it will use
|
|
|
|
|
in memory.

|
The main parts of a class are fields and methods. One for storing data and one
|
|
|
|
|
for processing that data. Fields are placed at the top of the class and look
|
|
|
|
|
like general variable declarations. Methods can take in arguments and also use
|
|
|
|
|
the fields declared in the class. They can modify data in the object or just
|
|
|
|
|
return some data to the caller.
