The Quidditch Championship
This is a modified passage from the book: Harry Potter and the Half-Blood Prince.
We're going to convert this passage into code. The code starts with the number of points scored by gryffindor and ravenclaw.
public class Championship {
public static void main(String[] args) {
int gryffindor = 400; //gryffindor points
int ravenclaw = 200; //ravenclaw points
}
1. Calculate the difference in points.
Make an int variable called margin. It will calculate the margin of points gryffindor scored over ravenclaw.
public class Championship {
public static void main(String[] args) {
int gryffindor = 400; //gryffindor points
int ravenclaw = 200; //ravenclaw points
// margin: amount of points by which gryffindor scored over ravenclaw ;
}
}
2. if - else if - else.
If gryffindor wins by a margin of 300 points or more, print:
Gryffindor takes the house cup!
If gryffindor wins by a margin of any points or ties, print:
In second place, Gryffindor!
If gryffindor loses within 100 points, print:
In third place, Gryffindor!
else, print:
In fourth place, Gryffindor!
Run your Code
Test Case 1
int gryffindor = 400; int ravenclaw = 200;
>>In second place, Gryffindor!
Test Case 2:
int gryffindor = 850; int ravenclaw = 500;
>>Gryffindor takes the house cup!
Test Case 3:
int gryffindor = 620; int ravenclaw = 500;
>>In second place, Gryffindor!
Test Case 4:
int gryffindor = 450; int ravenclaw = 500;
>>In third place, Gryffindor!
Test Case 5:
int gryffindor = 100; int ravenclaw = 500;
>>In fourth place, Gryffindor!
Visualizing the Runtime
After you solve this workbook, I still recommend watching the video solution on Udemy.
It will show you how to visualize the runtime using Visual Studio Code.
