Java Inheritance, Polymorphism, Abstraction and Encapsulation

Java Inheritance, Polymorphism, Abstraction and Encapsulation

• Java Classes - Normally have relationship with other classes and contain methods
• Accessors - Are methods that are used to access information from the class (getter).
• Mutators - Are methods that manipulate data within the class (setter)
• Inheritance - Is a relationship were one class inherits attributes and/or behaviors from another class.

• Encapsulation - AKA Data hiding, encapsulation is like a protective barrier protecting the code from other code from outside the class.
  

• Polymorphism - Allows  the object to take many forms, a example would be a child class refers to parent class.
  
  
  
  
• Abstraction - The ability to make a class abstract in OOP, an abstract class can not be instatiated.
