Object Oriented Programming

1. Object

   • Something that has attributes and can perform actions
   • Class determines the types of objects you can get

2. Class

   • Blueprint to create objects of identical types
     • Three important factors for creating a class: Class name, fields (attributes), methods (actions)
       • Class name: The name or descriptor of your class, formatted with keyword class followed by className
       • Fields are variables or traits of any given object in the class that follow the camel case naming convention (validAddress, maxAge)
       • Methods define actions that the objects of the class can do, has a declaration part and a body
     • Constructors
       • Every class must have at least one and it is used to create an object
