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.
What is a class? Classes are blueprints describing attributes and behavior that you use to create objects while programming. In Object-Oriented languages, you'll work with a lot of classes already written, such as the Java Class Library. This availability enables you to create objects without also having to create the same classes repeatedly for each program.
