Reminder: This is a bare code without any class or function/method heading around the code. Just the nested loop
The term "Pre-test" means that The loop is tested after the body statements are run. OThe loop is tested after the loop is run through for the first time OThe loop will be tested before the statements to be repeated are executed, even once. OThe loop will be tested before the next iteration (after the first)
(Simulation) Write a program to simulate the roll of two dice. If the total of the two dice is 7 or 11, you win; otherwise, you lose. Embellish this program as much as you like, with betting, different odds, different combinations for win or lose, stopping play when you have no money left or reach the house limit, displaying the dice, and so forth. (Hint: Calculate the dots showing on each die with the expression dots=(int)(6.0randomnumber+1), where the random number is between 0 and 1.)
Problem: Feed Nibble Monster As Long As It Is Happy Write a program in which the Nibble Monster happily keeps asking for nibbles until the user gives it something that is not a nibble. At that point the monster becomes unhappy and the loop ends. Use do-while loop. HINT: You can control the loop with a boolean variable which indicates the state of Monster's feelings: it is true initially but becomes false when the Monster receives a non-nibble. Sample Runs: weron@DESKTOP-218KDUL MINGW64 /c/courses/CS2011/code $ java NibbleMonsterWithLoopwhileHappy Monster hungry :E Feed monster nibble :0 c yum! Feed monster nibble :0 F YUM!

Design the worst calculator ever: an application that accepts two numbers from the user and, when a button is pushed, performs a single operation and displays the results. You may choose: Multiplication, Division, Subtraction, square root, or raising the first number to the exponent of the second number. Don't use addition as we already did that in class. The result must be displayed to the user only when an appropriately labeled button is pushed.
Using a Sentinel Value to Control a while Loop Summary In this lab, you write a while loop that uses a sentinel value to control a loop in a Java program that has been provided. You also write the statements that make up the body of the loop. The source code file already contains the necessary variable declarations and output statements. Each theater patron enters a value from 0 to 4 indicating the number of stars the patron awards to the Guide’s featured movie of the week. The program executes continuously until the theater manager enters a negative number to quit. At the end of the program, you should display the average star rating for the movie. Instructions Ensure the file named MovieGuide.java is open. Write the while loop using a sentinel value to control the loop, and write the statements that make up the body of the loop to calculate the average star rating. Execute the program by clicking Run. Input the following: 0, 3, 4, 4, 1, 1, 2, -1 Check that the average…
The term "for construct" refers to a type of loop that can iterate over multiple items. So long as there are objects to process, it will continue to operate. Is this a true or false statement?

Problem 1 - Methods Write a program that has a loop of three iterations. In every iteration, the program should prompt the user to enter three integers then invoke a method called hasOddEven that takes the three integers as parameters and returns true if there is at least one odd and at least one even among the three numbers and that returns false otherwise. Below are some sample calls and the returned value: Method Call Value Returned hasOddEven(2, 4, 6) False hasOddEven(2, 3, 4) True hasOddEven(12, 4, 17) True hasOddEven(7, 19, 5) False Problem 2 - Arrays Write a method that takes an array of integers and print the elements of the array. The header of the method is: public static void displayArray (int [] arr) Write a main method in which you create an array named a of size entered by the user (the size should be even). Then fill the array a with values read from the user. Split the array a into two arrays b and c as follows: a 4 65 23 94 12 56 33 89 34 23 b 4 65 23 94 12 56 33 89 34…
Create a class name AddAgain for do-while loop that asks the user to enter two The numbers should be added and the sum displayed. The loop should ask the user whether he or she wishes to perform the operation again. If so, the loop should repeat; otherwise it should terminate.
Dice game Rules of the game: The players roll three dice, and the program adds the sides that turn up. After the first roll of the three dice, a player may choose to roll the dice as many times as they wish until the player gets at least one side 2 from a dice. When a player gets at least one side 2 from the dice, that player's score drops to zero, and the turn switches to the other player. Both players play the game for an equal number of turns, and the player who gets a score higher than 18 wins. If both players get a score higher than 18 within an equal number of turns, the player with the higher score wins. If both of the players got the same scores, print the scores of the players. These are the minimum required functions for this program. Design and implement these functions. You can create more functions if you choose to. Here is the provided starter code: # A program to play a Dice game. import random def roll_die(): ''' Simulate a die roll ''' def…
