ExitOnce a menu is selected, the appropriate action should be taken and once this action is finished,the menu should reappear. Unless the user selects the ‘Exit’ option the program should continueto work.Note: Consider array of random numbers from user to find Prime Numbers/Odd/Even and userentered value for factorial.20- $footboll=array(); is an example of: a. boolean b.

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…
- Homework - identical arrays for one-dimensional: Write a test program which prompts a user to enter the size of two arrays as well as to fill their elements. After that, the program checks the same contents of the elements of the two arrays. If these arrays are equal, the program displays message which is "The two arrays are identical". If not equal, displaying "The two arrays are not identical". Write an equals method that reads two arrays and displays these messages above.8. Grade Book A teacher has five students who have taken four tests. The teacher uses the following grading scale to assign a letter grade to a student, based on the average of his or her four test scores: Test Score Letter Grade 90–100 A 80-89 B 70-79 C 60-69 D 0-59 Write a class that uses a String array or an ArrayList object to hold the five students' names, an array of five characters to hold the five students' letter grades, and five arrays of four doubles each to hold each student's set of test scores. The class should have methods that return a specific student's name, the average test score, and a letter grade based on the average. Demonstrate the class in a program that allows the user to enter each student's name and his or her four test scores. It should then display each student's average test score and letter grade. Input Validation: Do not accept test scores less than zero or greater than 100.Java - Functions with 1D Arrays Create a program that asks the user for the size of an integer array and the elements of the array. Then, create a function called maxArray() with the following details: Parameters: An integer array The size of the integer array Return type - int Return value - the maximum value of the integer array Call the function you created in the main and pass the integer array and its size to it. Make sure to store the return value in a variable so you could print it afterwards. Input 1. First line contains the size of the array 2. Succeeding lines are the elements of an array 3. First line contains the size of the array 4. Succeeding lines are the elements of an array 5. First line contains the size of the array 6. Succeeding lines are the elements of an array 7.

- Project 5 - Magic Squares Objectives The objective of this project is to have students practice with two-dimensional arrays and loops. Specifications In this project, you will write code to determine if a two-dimensional array of ints is a Magic Square. For a two- dimensional array of ints to be a Magic Square all of the following must be true: 1. The array must be square - in other words, the lengths of all rows and all columns must be the same. 2. The array must contain all integers from 1 to n*n, where n is the length of the rows and columns. 3. The sum of the numbers in each diagonal, each row, and each column must be the same. You have been given two classes: • MagicSquareTest.java - Contains JUnit test cases for the MagicSquare class. Your code must pass all these tests. • MagicSquare.java - contains static methods to determine if a two-dimensional array of ints is a Magic Square: o isMagicSquare() - returns true if a two-dimensional array of ints meets all the criteria to be a…Recipe Program - Java ONLYI am looking to create a program that is a recipe holder. It needs to include at a minimum: At least 1 loop An Array or ArrayList At least 3 Java classes Use of methods The program would allow the user to (as part of a menu selection): Add a recipe Include ingredient list Instructions List all recipes that are in the program (array) Display a single recipe Search Recipes (option to view recipe selected) For example, searching for peanut butter cookie would bring up the recipe or multiple if the same name. The user could then select one of them to view the recipe. Search Recipes with a single ingredient (option to view recipe selected) For example: search for coconut and it would bring up coconut cream pie and German chocolate cake. The user could then select one of them to view the recipe.
