I almost finish the section “Testing Interfaces” and still don’t see what is the purpose or benefits of interfaces…
Maybe it’s me or the exercises are too repetitive

Someone here explains it pretty well. It might be a good idea to go check the forum at the end of each page to see if someone added any information you were missing.
Hope this helps.

I am still confused about get and set. Why is it that we can write a constructor that set properties to certain values even when those properties have no setter? And then later, when we want to make a method that increases Speed, we must then make sure that Speed has a setter? Can someone help me understand this?
