- IN C++ Lab #6: Shapes Create a class named Point. private attributes x and y of integer type. Create a class named Shape. private attributes: Point points[6] int howManyPoints; Create a Main Menu: Add a Triangle shape Add a Rectangle shape Add a Pentagon shape Add a Hexagon shape Exit All class functions should be well defined in the scope of this lab. Use operator overloading for the array in Shape class. Once you ask the points of any shape it will display in the terminal the points added.Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format. Student number PMark EMark MMark Mar#9186 81 64 72.00 1.2 Create a testStudents class.

After the customer enters the appropriate prompted values, the program will calculate the cost of the framing based on the specifications outlined below. The program should allow the user to order a second frame if desired. Define a java instance class as described below. Save the class definition in a file with an appropriate filename. Class Name: Frame Instance Variables: length – float (representing inches) (Fields) width – float (representing inches) type – char (valid values P, W, or M for Plastic, Wood, or Metal) matte – integer (representing the number of matting layers) Static Variable: count – tracks the number of frames created Instance Methods: A constructor that accepts no arguments and sets default values as follows: the length to 8,…
- Programming Language= PYTHON 3. Personal Information Class Design a class that holds the following personal data: name, address, age, and phone number. Write appropriate accessor and mutator methods. Also, write a program that creates three instances of the class. One instance should hold your information, and the other two should hold your friends’ or family members’ information. My information: Name: John Doe Address: 111 My Street Age: 22 Phone Number: 555-555-1281 Mom's information: Name: Mom Address: 222 Any Street Age: 52 Phone Number: 555-555-1234 Sis's infomation: Name: Jane Doe Address: 333 Her Street Age: 20 Phone Number: 555-555-4444 Dad's information: Name: Dad Address: 222 Any Street Age: 56 Phone Number: 555-254-5611PART 2: Pets Examine carefully the UML class diagram below: NOTE: Class Reptile was missing a toString() method. It has now been added. class Pet has an attribute of type java.util.Date. no specific dates are required for this attribute. compareTo(Dog) compares Dogs by weight. Create executable class TestPet as follows: create at least one Reptile pet and display it create an array of at least four Dog pets sort the array of Dogs by weight use a foreach loop to fully display all data for all dogs sorted by weight (see sample output)array of Payroll ObjectsDesign a PayRoll class that has data members for an employee’shourly pay rate and number of hours worked. Write a program withan array of seven PayRoll objects. The program should read thenumber of hours each employee worked and their hourly pay ratefrom a file and call class functions to store this information in theappropriate objects. It should then call a class function, once foreach object, to return the employee’s gross pay, so this informationcan be displayed.
- Java programing ShipsStudy the UML diagram carefully. The green spots signify public. The red squares signify private. Superclass Ship is abstract because it contains the abstract method purpose. This class also implements the Comparable interface to compare ships by tonnage. Ship also has a public static integer named numShips that is incremented in the constructor to serve as a counter for the number of ships.After coding these classes, write a program named TestShips that uses them as follows:⦁ Create an array of declared type Ship that contains at least six ships (two of each concrete subclass). You can make up all of the values for the data members of each ship.⦁ The Strings returned by purpose() can be determined by viewing the Possible Output below.⦁ Process the array in an enhanced for loop to display for each ship:⦁ The actual type using the getClass() method inherited from class Object.⦁ The output of the toString() method.⦁ The value returned by the purpose()…Nutritional information (classes/constructors) PYTHON ONLY Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's10.034.02.01.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is:…Java Questions - (Has 2 Parts).

The constructors and methods all function in the standard way, except: The equipmentRequired method should return “Record Player” or “CD Player” as appropriate.The getAlbum method of the NinetiesMusicCollection class accepts an index and returns the corresponding Album object. This method throws an IllegalArgumentException if the index is out of range. (This is the only exception you have to throw anywhere in your code.)In the NinetiesMusicCollection constructor, you can assume the ArrayList<Album> object passed as an argument is not null . Don’t worry about privacy leaks.Implement this set of classes in Java. Note the italics on the Class name “Album” and the method name “equipmentRequired” in the Album class.A(n) _______ is a special constructor, called whenever a new object is initialized with another object’s data.
