Wednesday (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
