Class ex: Employee

Class ex: Employee

1. Attribute: age

   • int getAge ()

2. Attribute ex: salary

   • returnType methodName (list of arguments)
     • double getSalary ()

3. subClass ex: Address

   • Attribute ex: Address address

4. "Constructors"

   • Create objects "Instances" out of the class
     • Looks like a method but with no return value
       • Must have same name as Class ie: Employee
         • Examples:
           • public class Employee {...}
             • Employee employee = new Employee ()
               • Employee.age = 40
               • Employee.salary = 90000.00
               • new Employee (40, 90000.00)
                 • "new" creates instantiation of object under class
                   • will be "null" until an actual employee instance is created
               • creates an object, employee, reference of type Employee
