Homework 2
Write a Java program complete with full documentation to play the game, "GUESS THE
NUMBER", with a human user. Your program must randomly select a target integer from 1
to 64, and it is up to the program user to guess the correct number. After each guess, the
program must tell the user if the guess is too high, too low, or correct. A sample interaction
would be the following (suppose the random target number selected was 40). The user input
will be underlined.
Welcome to the GUESS THE NUMBER program.
Make a guess (from 1 to 64) and press RETURN
32
Your guess of 32 is too low.
Make a guess (from 1 to 64) and press RETURN
48
Your guess of 48 is too high.
Make a guess (from 1 to 64) and press RETURN
40
40 is CORRECT!!
In order to obtain the random number to be guessed, download GuessNum.java from the CSCI
2310 web page. This contains the definition of a code segment that will provide you with a
random number to guess. You will have to include this code appropriately as part of your overall
program for playing the game. It will define a variable named target that will contain the number
to guess.
Note that as part of the execution of this code it will prompt you with the statement “Enter integer
seed from 1 to 100000”. The purpose of this is to initialize the random number generator. This
will not be the actual random number generated. What you are able to rely on is that every time
you execute the program and input a particular number as the integer seed, the random number
generated will always be the same.
• ERROR HANDLING: This program should do the following type of error handling:
The program normally terminates when the person makes a correct guess. However, we
do not wish to waste computing resources on a user who is not guessing intelligently.
Define a constant MAXGUESSES and set it to 8. See page 57 of your text for
information about defining constants. Whenever the number of guesses that a user makes
will exceed MAXGUESSES without having given a correct guess, the program should
issue an appropriate message saying that the user has exceeded the maximum number of
guesses, and terminate the program.
