Wednesday (10/15/15)
Agenda:
- Complete the Point class definition
Monday (10/13/15)
Agenda:
- Demo missing assignments
- IA Progress Assignment (due tomorrow!) - via Google Classroom
- You will upload any/all code or tutorial documentation to justify your progress on the Internal Assessment.
- You must submit at least 3 artifacts demonstrating Internal Assessment progress for full credit.
- You may include screenshots of tutorial completions (e.g. CodeAcademy).
- At the top of each file, annotate the code or screenshot, explaining what it is and how it is a reasonable artifact for your Internal Assessment
- You may upload multiple files. Be sure to include your name in each document.
- LATE submissions will be penalized
- Java Functions/Methods Review
- Media:JavaMethods.pptx
- Method Definitions
- Method Return types
- Method Parameters
- Method Calls
- 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 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
Thursday (10/8/15)

Tuesday (10/6/15)
Agenda:
- Search and sort quiz

- Write a function: matrixAdd(a, b) that returns a new matrix that is the sum of a and b
- Be sure to check if the two matrices are the same size (if not, then return null)
- Write a function: fliplr(m) that returns a new matrix that is the horizontal flip (left to right) of matrix m
- Write a function: flipud(m) that returns a new matrix that is the vertical flip (up to down) of matrix m
- Extra Credit: Write a function: matrixMult(a, b) that returns the product of matrix a and b
- Be sure to check the rules of matrix multiplication
- Return an null matrix if their sizes are different
- Write a function: matrixAdd(a, b) that returns a new matrix that is the sum of a and b
- Challenge: Write the function det(m) which returns the determinant of any matrix m
