OOP with Java

1. Classes

2. Classes: A class is a blueprint or prototype from which objects are created

   • Instance Variables
     • Access Modifiers
       • + Public, - Private, # Protected
         • Public modifier—the field is accessible from all classes. Private modifier—the field is accessible only within its own class.
   • Methods
     • Get and Set
   • The first letter of a class name should be capitalized.
   • Instantiation
     • Note: The phrase "instantiating a class" means the same thing as "creating an object." When you create an object, you are creating an "instance" of a class, therefore "instantiating" a class.
