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.
A method is a function attached to an object. In the above code myObj.work is a method. In the above code myFun is an example of function. 1  As a function, the way everyone knows it. 2  As a method. A method is a function attached to an object.  As a constructor call.
