Sorry.Wrong question. Actually, the question is, how do I implement a method,such as compareTo, from the interface,Comparable, and use this method so that squares are compared according to their sides?

I've already fallen a handful of times while learning how to ride a bike at the age of 45. I only rode the bike once without falling. How often would you expect one would fall while learning how to ride a bike?
http://www.learnrosettastonenow.com/ How long before I get used to riding where I won't fall? A few days, a week, a month? Thx.
