Thursday (2/20/20)
Warmup:
- Complete the Point class repl.it warmup
Agenda:
- Inheritance & Polymorphism Quiz on Monday (2/24/20)
- Inheritance review
- Used to create superclasses comprised of common attributes (instance variables) and behaviors (methods)
- extends keyword - subclasses inherit all things public from the super class (except for constructors)
- super() - method can be used to call any of the superclass's constructors (0 or more parameters can be used if it matches)
- Class Hierarchies
- Polymorphism - same method names but different ... (parameters or objects)
- Overriding methods - subclass method overriding superclass method of the same name
- Where else have we seen overriding methods?
- Object super class
- equals()
- toString()
- Animal class example
Homework:
- Complete eIMACS: Test 14: Inheritance & Polymorphism
Tuesday (2/18/20)
Warmup:
- Complete the Circle class repl.it warmup
Agenda:
- Inheritance and Polymorphism
- Extending classes - extends keyword
- super() method call
- Complete Activity 17: Airplanes
- Demonstrate Employee and Company classes
Thursday (2/13/20)
Agenda:
- Work on and complete the Employee & Company classes (specifications below)
- Prepare your own main() to demonstrate that everything works

Tuesday (2/11/20)
Agenda:
- NetBeans review
- Complete the ArrayList repl.its
- sum()
- min() & max()
- ArrayList<Card> examples
- Total the value of your hand
- Finding the smallest Card (minimum)
- Finding the largest Card (maximum)
- Finding a card (i.e. search)
- Sort your Cards
- Expectation: you should be able to repeat any of the above with any object!
- Employee class
- instance variables: (these should be private)
- name (text)
- experience (whole number years of experience)
- salary (floating point number)
- methods (these should be public)
- constructors (default and specific)
- setters and getters (accessors and mutators) for all instance variables
- String toString() - returns a String that represents the Employee (all the attributes)
- instance variables: (these should be private)
- Company class
- instance variable:
- ArrayList<Employee> employees
- methods (these should be public)
- constructors (default and specific) - instantiate your ArrayList
- void addEmployee(Employee e) - adds the Employee object e to your employees ArrayList
- void listAllEmployees() - prints out all the employees
- Employee getMostExperienced() - returns most experienced Employee
- Employee getHighestPaid() - returns the highest paid Employee
- Employee getLowestPaid() - returns the lowest paid Employee
- double getSumOfSalaries() - returns the sum total of all the salaries in employees
- void sortByYearsOfExperience() - sorts employees by years of experience
- instance variable:
