Lecture 2 Summary

Inheritance

• is-a relationship
• The use of super(...) to access the parent's constructor
• super.method() or super.attribute to access the parent's method and attribute accordingly

private vs protected

Think of it as treating something like your private bedroom where only you can get in VS your family room where... your whole family can access!

Overriding (@Override) vs Overloading

• Overriding: explicitly defining a method that is the same as the method inherited from another class
• Overloading: having more than one methods to co-exists as long as the arguments are different in configuration
