The Fission Theory: This theory proposes that the Moon was once part of the Earth and somehow separated from the Earth early in the history of the solar system.
When you actually use that class to make a THING, this is what you make. A method is a bit of code that can be called when needed (often as part of an class, but not always) Here's an example: I write a class called Ball. In my main code, I then write a=Ball.new, b=Ball.new, c=Ball.new.
Part of the Programming glossary: In object-oriented programming, a class is a template definition of the method s and variable s in a particular kind of object. Thus, an object is a specific instance of a class; it contains real values instead of variables. The class is one of the defining ideas of object-oriented programming. Among the important ideas about classes are: 1  A class can have subclasses that can inherit all or some of the characteristics of the class. 2  In relation to each subclass, the class becomes the superclass.
