Agenda:
- Demo assignments
- Queues - Media:Queues.ppt
- Data Structure Visualizations
- Work on Java - Static Queue Assignment
Thursday - Monday (10/20/16 - 10/24/16)
Agenda:
- Demo Person, Car, Vector classes
- Introduction to Stacks - Media:Stacks.ppt
- Be able to describe the characteristics of a stack
- Be able to explain the operations of a stack
- Be able to describe different stack applications
- If given a list or an array, be able to explain their use as stacks
- Data Structure Visualizations
- Practice Stack Exercises
- Push the following words onto a stack: "Washington-Lee", "Generals", "Computer", "Science". What will the words be in the order of popping them all.
- Imagine that you are stuck in a dungeon. You are using a stack to keep track of your movements so that you can find your way back to the beginning of the dungeon. Diagram the stack after the following moves: forward, left, left, right, forward, forward, right, forward, left. Using your stack, what would the order of moves be to return back to your starting position?
- Assume you are given a list of numbers that you can only access one at a time in their order. Describe how you would use stacks to reverse their order
- Static-sized Stack class walk-through
- Implement a Stack using a static data structure (e.g. array)
- Test out our implementation to find weaknesses
- Fix the weaknesses in our implementation

Monday (10/17/16)
Agenda:
- Mr. Bui has jury duty
- Use class time to work on any missing assignments (e.g. MatrixMult, Person, Car, Vector, etc.)
- If you have no missing assignments, then you should work on your Internal Assessment
Thursday (10/13/16)
Agenda:
- Female CS Students Scholarship Opportunity
- Complete and demo the following:
Homework:
- Complete the following if you did not finish in class!
Thursday - Tuesday (10/6/16 - 10/11/16)
Agenda:
- Demo your matrix functions
- Java Objects
- Point Class assignment walk-through
- You will create two java files: Point.java and PointMain.java
- Point.java - the Point class definition will be here
- PointMain.java - only the main() method will be located here
- Declare and initialize the following private attributes in the Point class
- double x = 0.0
- double y = 0.0
- Define two Point() constructors:
- default constructor: Point()
- specific constructor Point(double newX, double newY)
- Define the following public methods in the Point class
- double getX() - returns the x-coordinate
- double getY() - returns the y-coordinate
- void setX(double newX) - sets the x-coordinate to the new x-coordinate parameter
- void setY(double newY) - sets the y-coordinate to the new y-coordinate parameter
- String toString() - returns a String representation of the Point object
- Go to your PointMain.java file to test out your Point class
- In the main method, create several new instances of Point objects
- Print out each of your Point objects
- Define a static method in PointMain.java named double slope(Point p1, Point p2) - returns the slope between p1 and p2
- Test and print out your slope method when you use it with your instantiated Point objects in the main() method
- You will create two java files: Point.java and PointMain.java
- Complete and demo the following:
Tuesday (10/4/16)
Agenda:
- Two-Dimensional Array Assignment
- Write a method (function): matrixAdd(m1, m2) that returns a new matrix that is the sum of m1 and m2
- Be sure to check if the two matrices are the same size (if not, then return null)
- Write a method (function): matrixMult(m1, m2) that returns the product of matrix m1 and m2
- Be sure to check the rules of matrix multiplication
- Return a null matrix if their sizes do not allow for proper multiplication
- Write a method (function): matrixAdd(m1, m2) that returns a new matrix that is the sum of m1 and m2
