about the super
posted 13 years ago
As I mentioned in your other post, the 'super()' is a call to a constructor of the super class. If your call 'super()' contains no arguments, it will just call the default constructor of the super class, or go up the chain until it finds a default constructor. If it has arguments ( like (i + 1) ), then you know that the constructor of the super class requires some sort of arguments (int I'm guessing).
