Guess the number

Design and implement a Java application to address the following problem description. Your

implementation should be strictly based on your own design and creativity will be

rewarded.

Problem Description

Learning about your outstanding programming skills, the principal of your local primary

school wants you to develop a fun number game for his students.

Student will first input their name and age. The program should then generate a random

number within the following range based on student’s age:

Age (years) Range (inclusive)

4-7 1-25

8-12 1-25

12+ 1-30

For example, if a student is aged 9, the program should generate a random number

between 1 and 15 (inclusive). Hint: You can use the inbuilt Math.random() method to generate a

random number in Java.

Students below 4 years of age are strictly not allowed to continue due to their notorious

history of smudging water colours on the school’s only laptop! The program should exit with

an appropriately stern warning.

Each student should get 10 attempts per game to guess the number. In case of a wrong

attempt, the program should display ‘GO HIGHER!’ if student’s guess is lower than the

number generated or ‘GO LOWER!’ if it is greater. If student makes a correct guess, the

program should score student for the game based on number of attempts required to make

the correct guess.

Number of attempts Score (out of 5)

1-3 5

4-6 3

7-10 1

No score is awarded if the student is unable to make a correct guess within the allowed 10

attempts.

After each game, student can either continue playing the game or choose to exit the

program. When the student finally chooses to exit, the program should display the following

overall statistics:

1. Total number of games played

2. Number of games where correct guess was made

3. Overall score of the user in following format -

“Hello Patrick, you scored 12 out of possible 15.”

Bonus Task (10 marks):

Modify your program so that the random number generated is always a prime number.

Hint: A prime number is a number that is divisible only by itself and 1 (e.g. 2, 3, 5, 7, 11).
