My best shot came up short
I think I met all the requirements but obviously am misinterpreting something. Tried debugging with cmd line input of single space between arguments and the 8 30 8 4 format and both add a line to the file that looks ok to me but the verification is none to happy.

WHy won't my code work?
Isn't it true that all years that are leap years are divided by 4? In which case I do not need to check if it is also divisible by 400, nor do I need to find out if it is divisible by 100.

Why can't I call a constructor by creating a new object in a constructor?
I run the code. The results are: 5.0 5.0 1.0 10.0 5.0 10.0 It did make the radius to 10.0, but it still failed. Why? What's the difference between "this" and an object? What is "the correct arguments" exactly?
