In this homework assignment, you are going to code a java program which uses random numbers to
create a guessing game. This will give you practice with random numbers and loops while allowing you
to explore and understand a little more Java code.
You will also need to test out this program to ensure the correctness of the algorithm and code. You will
need to develop test data that will represent all possible kinds of data that the user may enter.
You are going to write a program that allows the user to play a simple guessing game in which your
program thinks up an integer between 1 and 100 and allows the user to make guesses until the user gets
it right. (The program also counts how many tries it took to get the correct number). For each incorrect
guess you will tell the user whether the right answer is higher or lower. Your program is required to
exactly reproduce the format and behavior of the log of execution.
Program should output: (Sample user output written in bold)
This program…
Guess-the-number-game: Write a program that pays the game of “guess
the number” as follows: Your program choose the number to be guess by
selecting an integer at random in the range 1 to 1000. The program then
displays the following:
I have a number between 1 and 1000.
Can you guess my number?
Please type your first guess.
The player then type a first guess. The program responds with one of the
following:
1. Excellent ! you guessed the number!
Would like to play again (y or n)?
2. Too low. Try again.
3. Too high. Try again.
If the payer’s guess is incorrect, your program should loop until the player
finally get the number right. Your program should keep telling the player
Too high or Too low to help the player “zero in” on the correct answer.
Write a program that prints the insurance fee to pay for a pet according to the following rules:
(Note: must use a switch statement to determine pet fee)
A dog that has been neutered costs $50.A dog that has not been neutered costs $80.A cat that has been neutered costs $40.A cat that has not been neutered costs $60.A bird or reptile costs nothing.Any other animal generates an error message.
The program should prompt the user for the appropriate information: a character code for the pet type, and a yes/no response for the neutered status. Use a code letter to determine the kind of animal (i.e. D or d represents a dog, C or c represents a cat, B or b represents a bird, R or r represents a reptile, and anything else represents some other kind of animal). Use a code letter to determine the neutered status(i.e. Y or y represents yes, N or n represents no). The user should be allowed to enter the input in either upper or lower case.
It prints out the type of animal (full name of animal)…

- Alyssa is very particular about what she gets for dinner. The more hungry she is, the more she can not figure out what to eat! Write a short program that asks a few questions and then makes the correct suggestion based on the following rules: Alyssa considers any temperature below 50 to be cold and anything 50 and above to be warm. If it is cold and raining, Alyssa wants to have soup. If none of these rules apply, Alyssa will always have meatballs. Alyssa has to eat before class starts! When it is 15 minutes or less until class, she gets a sandwich. This is the most important rule. Your program should prompt the user with the following.

The program should then: simulate the dice roll (using the random function) and show what was rolled show what the user’s funds are after each roll ask the user if they want to roll again if the user wants to roll again, repeat the three actions above if the user does not want to roll again give some response and end the game the final output should show if they won or lost money, and how many rolls they playedarrow_forwardYou arrive in front of a bridge that you must cross to reach a village before dark. Crossing the bridge is not free - the bridgekeeper asks you to roll two dice to determine the cost. You decide to write a program to verify that he is charging the right price. Your program should read two integers, between 1 and 6, representing the values of each die. If the sum is greater than or equal to 10, then you must pay a special fee (36 coins). Otherwise, you pay twice the sum of the values of the two dice. Your program must then display the text "Special tax" or "Regular tax" followed by the amount you have to pay on the next line.arrow_forward

The program should display an error message if the user enters a number that is outside the range of 0 through 56. On a roulette wheel, the pockets are numbered from 0 to 36. The colors of the pockets are as follows: Pocket 0 is green. For pockets 1 through 20, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 21 through 38, the odd-numbered pockets are black and the even-numbered pockets are red. For pockets 39 through 48, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 49 through 56, the odd-numbered pockets are black and the even-numbered pockets are red.arrow_forwardphytonarrow_forward

The equation is:V = nRT / PSince we only have used integer arithmetic, all numbers will be integer values with no decimal points. The constant R is 8.314 and will be specified as (8314/1000). This gives the same result. Implement the idea gas law program where the user is prompted for and enters values for n, T, and P, and V is calculated and printed out. Be careful to implement an accurate version of this program. Your program should include a proper and useful prompt for input, and print the results in a meaningful manner.arrow_forward
