* Practice Free Response
** 22.5 minutes per question (90 minutes for 4 questions)
** Complete Question #2 from [https://apcentral.collegeboard.org/pdf/ap19-frq-computer-science-a.pdf 2019 AP CS FRQ]
** Rubric grade as a class

'''Homework:'''
* Complete eIMACS: Activity 13: Recursion
** You can review recursion concepts in the reading: Java Basics -> Methods -> Recursive Methods
* Complete repl.it: Recursion - Counting chars
* Complete repl.it: Recursion - Reverse String

== Wednesday (2/26/20) ==
'''Agenda:'''
* static keyword (for methods or for variables)
** binds the method or variable to the class NAME as opposed to the object instance
** static methods may *not* modify instance variables
** static method example
** static variable exists as a single copy for all objects
** static variable example
* final keyword
** makes the variable unchangeable
** final variable example
* Practice Free Response
** 22.5 minutes per question (90 minutes for 4 questions)

== 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
** A superclass reference variables can reference a subclass object
* Polymorphism - same method names but different ... (parameters or objects)
** Overriding methods - subclass method overriding superclass method of the same name
** ...casting may be necessary depending on your reference variable type
** Where else have we seen overriding methods?
* Object super class
** equals()
** toString()
* Animal class example
