You are required to write a program to build a class JewelleryItem. A jewellery Item has a type (string) , price (float),material (string), daysToGo (int).These attributes represent the type i.e ‘ear ring’, necklace, finger ring etc. The material can be gold,silver, plastic etc. The daysToGo attribute represents the number of days it will remain fit for use.1. You are required to provide the following parameterized constructors JewelleryItem(string type, float price, string material, int daysToGo) Jewlleryitem(string type, float price, int daysToGo) // the material will get “gold” as default JewelleryItem(string type, float price) //the material defaults to gold and daysToGo defaults to100.2. Now provide getters for each of the attributes above but setters for only price, daysToGo3. Provide a function/method makeUse(). This function represents the use of this item for one daywhich reduces the daysToGo by 1. This function returns true if the daysToGo is greater than 1 andfalse…
You are in process of writing a class definition for the class Book. It has three data attributes: book_title, book_author, and book_publisher. The data attributes should be private. In Python, write a setter/mutator method and a getter/accessor method for book_title(only) that will be part of your class definition. Note: You do not need to write the entire class definition. Just the two methods mentioned.
In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.
This program should be written in Java: Hamburger Joint: Hamburger ClassWrite a Hamburger class with the following six attributes: • bun - the type of bun the burger will be on • patties - the number of patties on the burger • cheese - whether or not the burger will have cheese • price - the price of the burger • toppings - an array of five toppings; it will need to start empty Write getters/setters for all attributes except the toppings array. Your constructor should create a single on white with no cheese and no toppings with a price of $2.99. Your class should include the following methods in this order, please: addCheese - this method has no parameters that adds cheese to the burger and increases the price by 75 cents superSizeIt - this method has no parameters and adds a patty to the burger and increases the price by 1.50 addToppings - this method would present the user with at least five toppings (your choice) stored in an array of String objects. If the user indicates the wants…
In this exercise, you have to calculate the student's total marks using the concept of Classes Problem Statement# Write a Java class called Student with ● private fields: ○ name(String type) ○ mark1 and mark2 (double type) And methods: ● getMarks(int markNumber), a method which should return mark1 if markNumber equals 1 and mark2 otherwise. ● calcTotal() method should take the two marks entered and return their sum. Also define two constructors: ● A default constructor that takes no parameters and initializes the values to zeros and null. ● A constructor that takes the three variables and sets them as the values of the appropriate fields. Input# Name of the student and the marks obtained in the first and second tests Output# Sum of both marks Sample Input# Student student = new Student("Jack", 60, 70); Sample Output# getMarks(1) => 60 getMarks(2) => 70 calcTotal() => 130.0 Part of solution class Student { // Define private fields here public Student() { // Write…

Build the ItemToPurchase class with the following specifications: Attributes item_name (string)item_price (int)item_quantity (int)Default constructor Initializes item's name = "none", item's price = 0, item's quantity = 0Methodprint_item_cost() Ex. of print_item_cost() output: Bottled Water 10 @ $1 = $10In the main section of your code, prompt the user for two items and create two objects of the ItemToPurchase class. Ex: Item 1Enter the item name:Chocolate ChipsEnter the item price:3Enter the item quantity:1 Item 2Enter the item name:Bottled WaterEnter the item price:1Enter the item quantity:10 Add the costs of the two items together and output the total cost. Ex: TOTAL COSTChocolate Chips 1 @ $3 = $3Bottled Water 10 @ $1 = $10 Total: $13
