Java's Object Orientation, I/O

CS 161 - Java

Key aspects of Object Oriented Programming

Encapsulation

A class should contain all the logic necessary to define how objects of the class work and no more.

Inheritance

In Java one class extends another class. In doing so the derived class should do something in addition, or in a different way, from the parent (super) class.

Polymorphism

Objects can expose different sets of capabilities at different times during a programs execution.

In Java this is done by extending other classes and by implementing various interfaces.
