- Lab Goal : This lab was designed to teach you more about recursion. Lab Description : luckyThrees will return a count of the 3s in the number unless the 3 is at the start. A 3 at the start of the number does not count. /* luckyThrees will return the count of 3s in the number* unless the 3 is at the front and then it does not count* 3 would return 0* 31332 would return 2* 134523 would return 2* 3113 would return 1* 13331 would return 3* 777337777 would return 2* the solution to this problem must use recursion*/public static int luckyThrees( long number ){} Sample Data : 331332134523311313331777337777 Sample Output : 022132arrow_forwardThe code for a class, the code for a method, and the code for while and for loops with more than ones statement is enclosed in ____. /* and */ [ and ] { and }arrow_forwardQuestion Language: JAVA Keep Guessing Write a program that plays a number-guessing game to guess a secret number randomly generated within the range 1 and 10. The user will get as many numbers of tries as he/she needs to guess the number. Tell the users if their guess is right or wrong and if their guess is wrong let them try to guess the number again. You must generate the secret number using the Java Random class. When the user guesses a number he/she will have to take an input of his guessed number from the keyboard. The user will have to take as many inputs as needed to guess the correct secret-number. That means the code will keep looping as long as the guess is different from the secret number. Use a while loop to prompt the user to guess again if the guess is wrong. Create a class named NumberGuessingGame which will contain the main method, write all your code in the main method. Sample input and output: Suppose the random number generated is 6. I have chosen a…arrow_forward
- Rainfall Type Create a RainFall class that keeps the total rainfall in an array of doubles for each of the 12 months. Methods in the programme should return the following values: • the total annual rainfall; • the average monthly rainfall • the wettest month of the year • the month with the least amount of rain Demonstrate the class in its entirety. Validation of Input: Accepting negative amounts for monthly rainfall data is not permitted.arrow_forwardCharge Account Validation Using Java programming Create a class with a method that accepts a charge account number as its argument. The method should determine whether the number is valid by comparing it to the following list of valid charge account numbers:5658845 4520125 7895122 8777541 8451277 13028508080152 4562555 5552012 5050552 7825877 12502551005231 6545231 3852085 7576651 7881200 4581002These numbers should be stored in an array. Use a sequential search to locate the number passed as an argument. If the number is in the array, the method should return true, indicating the number is valid. If the number is not in the array, the method should return false, indicating the number is invalid.Write a program that tests the class by asking the user to enter a charge account number. The program should display a message indicating whether the number is valid or invalid.arrow_forwardRolling Dice Simulator [Java Assignment]Objective: Create a Java program that rolls two dice and displays the results. The program should have two Java classes: one for a single die and another for a pair of dice. Assignment Details: User Input: Ask the user to specify the number of sides they want on each die. Ensure that the user's input is within a reasonable range. Dice Rolling: Simulate rolling the dice using Math.random() based on the user's chosen number of sides. Display the sum of the values rolled, e.g., "5 + 3 = 8." Special Combinations: If the dice roll results in combinations of 2, 7, or 12, print special messages: "1 + 1 = 2 snake eyes!" "3 + 4 = 7 craps!" "6 + 6 = 12 box cars!" Main Method: In the main method, create a pair of dice, roll them, and display the results. Allow the user to decide whether to continue rolling the dice or exit the program. Additional Features: You are welcome to add more features or enhancements to the program if desired.…arrow_forward
- Happy Learning (this is a fictional scenario) The kindergarten allows the parents (caretakers) to select daily the menu for lunch. There are over 40 possible items to be included in the lunch menu. For a lunch item we keep a 4 digits code, its name (up to 28 characters), and the number of calories (an integer). A parent (caretaker) can make for each of his/her children a lunch order everyday. All orders made are stored. If no order is made in a day the last order made will be provided. An order consists of maximum 6 items. Same item cannot be ordered multiple times in the same order. The order does not store the caretaker who made the order. The Entities are: PARENT, CHILD, MENU, ORDER 1. Relationship Strength: Weak or Strong? 2. Relationship Type: (M:1, 1:1 etc) 3. What are the Cardinalities? PARENT to CHILD? CHILD to ORDER? ORDER to MENU?

A food truck has multiple food items as well as a menu which contains a selection of the food items which will be sold for that day. A maximum of 10 food items can appear on the menu for any day. For each food item keep a code, description, category, price and quantity in stock (code, description and category are not usually changed). Create a comma delimited text file called "items.txt" for 15 or more food items, indicating the item's description, category, price and quantity in stock. Read all the food items from the text file “Items.txt” Display all the food items available for this food truck. Continuously prompt the user for a food item’s code to be placed on the menu until the menu is full or the user enters -1. Note that only food items which have a positive quantity in stock may be added to…arrow_forwardThe enum class construct: Select one: a. does not require one to write anything in front of an enumeration value-name b. requires one to use the name of the enumeration, followed by "::" (colon-colon), before each name whenever the enumeration's value-name is used c. requires one to use the name of the enumeration, followed by "."
