Tuesday (9/17/19)
Agenda:
- Algorithm Identification Quiz 1
- Sorting Identification Quiz 1
- Class Construction Quiz on Thursday (9/19/19)
- Repl.it class construction assignments progress check
- Intro Poker Hand Methods
- int getHighCardValue(Card c0, Card c1, Card c2, Card, c3, Card c4)
- returns the value of the highest Card
- Do not continue with the other poker hand methods like above b/c we will be making new versions using arrays!
- int getHighCardValue(Card c0, Card c1, Card c2, Card, c3, Card c4)
- Introduction to Arrays of Objects
- Walkthrough -- take notes! Pay attention!
- Basic Card[] methods - implement the following, test, and demo for credit
- void printCards(Card[] cards) - we will do this one together
- Use a for loop to iterate through all the cards, and print them to the screen
- void shuffle(Card[] cards)
- Write a for loop that runs a bunch of times (e.g. 10000)
- Generate two random numbers from 0 to the length of cards
- Swap the cards at the locations of the two random numbers
- void sort(Card[] cards)
- Implement either selection sort or bubble sort to sort your Card[] array. You can literally copy and paste your sorting code from before, and then tweak it to use the value of the cards (i.e. getValue())
- You should be able to test your code by generating a bunch of cards, sorting it, and then printing it out. They should display in order of value.
- void printCards(Card[] cards) - we will do this one together
Friday (9/13/19)
Agenda:
- Search & Sorting Algorithms Quiz on Tuesday (9/17/19)
- You should be able to identify the algorithm visually
- You should be able to identify the algorithm if given code
- You should be able to fill in missing lines of code for any algorithms
- Java Objects Slides
- Point class assignment - complete in NetBeans or repl.it (*must* submit to repl.it for auto-testing)
- You will create two java files: Point.java and Main.java
- Point.java - the Point class definition will be here
- Main.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 Main.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 Main.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 Main.java
- Complete the other repl.it assignments:
- Car class
- Vector class
- Card class
