Program 4

Due Date:

• October 21 at 11:55 PM

Problem:

A simulation program is needed to determine if the ISU Quiz Bowl Team should comprise mainly of genius students or regular students.

A primary requirement of this program that is different from your earlier assignments is that you are required to create 2 different Java classes in the design of your program. Here are some other design details that may be helpful:

Design:

The classes should be placed in a package with the name edu.ilstu

The all classes should have proper Javadoc comments

Student class

Keeps track of the brain power a student on the Quiz Bowl Team. This class should include the following:

• Instance Variables
  • studentName
  • studentType
  • currentBrainPower
  • currentScore
• Methods
  • Getters for each instance variable
  • A method, void study(int time), which increases the student’s currentBrainPower. A genius student (i.e. studentType == ‘g’) increases their currentBrainPower at the rate of 2 times each time unit. A regular student (i.e. studentType == ‘r’) increases their currentBrainPower at the rate of .75 times each time unit.
  • A method, int answerQuestion(int answer) that will calculate the student’s answer to the Quiz Bowl Simulator question. A regular student answers the question by generating a random number between 1 and 100, costing the student a loss of brain power of 5 points. A genius student answers the question by generating random numbers until they get a random number that is within plus or minus 15 of the answer passed in. For each random number that a genius student generates while trying to get within plus or minus 15 points of the answer, they suffer a brain power loss of 3 points.

• A method, void creditForBestAnswer(), that will add 1 to the student’s currentScore.

• A constructor Student(char type, String name) which initializes the student object using the two parameters for studentName and studentType. Genius students start with a currentBrianPower of 50 and regular students start with a currentBrainPower of 30,

QuizBowl class

This is the starting point for the application which is the only class to contain a main method. You will use the Student class here. For this program, the main method handles all of the input and output for the program and will perform the following tasks:

• Create two instances of the Student class, with one student being a genius and one being a regular student.  
• Have the genius student study for 2 hours.
• Have the regular student study for 6 hours.
• Loop until either one of the students runs out of brain power (i.e. currentBrainPower == 0) or one of the students reaches a score of 10 (i.e. currentScore == 10)
  • Generate the answer (i.e. a random number between 1 and 100)
  • Ask the regular student for their answer
  • Ask the genius student for their answer
  • Determine which student’s answer was closest to the answer
    • For the student whose answer was closest to the answer, give them credit for having the best answer.
• Display the winner’s name, type, score, and current brain power.
• Display the loser’s name, type, score, and current brain power.

I am working on the above assignment for my introductory Java class. I've created the methods, getters and required constructor but am now struggling with how to format the parameters and what kind of loops to use and how to format them. I am at my whit's end with this program and could use some assistance
