Answer 1

First of all I added 'toString' method that is use to print different attributes of a class.

Secondly I suggest you to learn more concepts of oop like encapsulation(getters/setter) ,inheritance its uses that help you in better understanding.

Answer 3

Just wanted to add few points.

▪ When you inherit a class, you inherit everything that is either public, protected or members with no access modifier(default).
▪ You cannot override fields, they are hidden by child class.
▪ You can override non-static methods.
▪ Learn and practice constructors, getter and setter methods.
