Counters before or after constructor

Why is the counter initialized before the constructor? Does it matter? Can I put other variables above the constructor? Could I put the counter variables below the constructor?

Please use triple backticks to surround your code in order to get proper formatting.

You can put the variable before or after the constructor. The convention is to put it before.

Thanks for the answer and thanks for the tip about the code. That's way better.
