Answer 4

What do you mean with a regular method? Do you have an example ?

Answer 5

Without seperating it from regular programming. In the example there is a seperate call for the defined object. Cant we call that defined object without seperating it from the main programme. I mean not using static void (something) and then calling it afterwords

Answer 6

Regular means no OOP for you? Former times we called methods procedures or functions and it was a kind of structuring your code. Besides you only need to write a procedure/function once if it's called multiple times.
