This is for python class, so please answer in python 9.12 LAB: Product class In main.py define the Product class that will manage product inventory. Product class has three attributes: a product code, the product's price, and the number count of product in inventory. Implement the following methods: A constructor with 3 parameters that sets all 3 attributes to the value in the 3 parameters set_code(self, code) - set the product code (i.e. SKU234) to parameter code get_code(self) - return the product code set_price(self, price) - set the price to parameter price get_price(self) - return the price set_count(self, count) - set the number of items in inventory to parameter count get_count(self) - return the count add_inventory(self, amt) - increase inventory by parameter amt sell_inventory(self, amt) - decrease inventory by parameter amt
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…
in java create a class called publication that stores the title (a string) and price (type float) and date of a publication. Provide getters/setters and constructor also write an abstract method isOversize() .From this class derive two classes: book, which adds a page count (type int); and tape, which adds a playing time in minutes (type float). Each of the classes should have a getter/setters and constructors and provide definition to function called isOversize() to the book and tape classes. Let’s say that a book with more than 800 pages, or a tape with a playing time longer than 90 minutes (which would require two cassettes), is considered oversize. You can access this function from main() and display the string “Oversize” for oversize books and tapes when you display their other data.
The following code is in Java: public class Vehicle // Superclass { private double cost; public Vehicle(double c) { cost = c; } (Other methods . . .) // assume these are given and they’re OK. } public class Car extends Vehicle // Subclass { private int passengers; public Car(int p) { passengers = c; } (Other methods . . .) // assume these are given and they’re OK. } 1) What problems are in the code above?2) What is needed to fix the issue of the code?

If a new Product object is created with code set to "Apple", price set to 0.40, and the count set to 3, the output is: Name: Apple Price: 0.40 Count: 3 Ex. If 10…
IN JAVA PLEASE Child Class: Vegetable Write a child class called Vegetable. A vegetable is described by a name, the number of grams of sugar (as a whole number), the number of grams of sodium (as a whole number), and whether or not the vegetable is a starch. For the Vegetable class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use instance data variables where appropriate a toString method that returns a text representation of a Vegetable object that includes all four characteristics of the vegetable
Java Question - Based on code, which answer out of the choices "A, B, C, D, E" is correct. Question has one correct answer. Thank you. Part 2 - 10.

Java program Make a class Employee with a name and salary. Make a class Manager inherit from Employee. Add an instance variable, named department, of type String. Supply a method toString that prints the manager’s name, department, and salary. Make a class Executive inherit from Manager. Supply appropriate toString methods for all classes. Supply a test program that tests these classes and methods.
Use Java Code to this Please keep it simple 1. Create House Class with the following properties and methods Properties: a. floorSize b. noOfFloors c. noOfDoors Methods: d. switchOn()(print something here to indicate switching on) e. lightOpen()(print something here to indicate light is open) f. ovenOpen() (print something here to indicate oven is open)2. Create TownHouse Class inherit the House class a. Create a main function b. In TownHouse modify the value of the following properties (noOfFloors and noOfDoors) (you may use static value)Inside main function:3. Instantiate the TownHouse Class once (create an object with TownHouse type)4. Display all the properties/attributes5. Calling the switchOn() will automatically execute lightOpen() and ovenOpen()6. Call switchOn() function.Note: You may create separate file for each class.
ANSWER IN JAVA: 3.14 (Date Class) Create a class called Date that includes three instance variables-a month (type int), a day (type int) and a year (type int). Provide a constructor that initializes the three instance variables and assumes that the values provided are correct. Provide a set and a get method for each instance variable. Provide a method displayDate that displays the month, day and year separated by forward slashes (/). Add a main method to the class that demonstrates class Date's capabilities. STANDARD OUTPUT: Enter·the·month,·day·and·year·in·the·form·XX·XX·XXXX·and·hit·enter:The·Date·object's·state·is:·11/5/1929↵ Enter·a·new·year:The·Date·object's·state·is:·11/5/1978↵ Enter·a·new·day:The·Date·object's·state·is:·11/12/1978↵ Enter·a·new·month:The·Date·object's·state·is:·6/12/1978↵
Q2: Write a complete JAVA program that carries out the following tasks: - Declare a class TV with the following non-static data members: ✓ name ( Type String ). ✓ price ( Type double). - The class also contains the following static data members: ✓ number ( Type int ). - The class also contains the following methods: ✓ default-constructor to give initial values for all data members. ✓ constructor that accepts values of all data members as arguments. ✓ setName () method to reset the name of the TV. ✓ getName () method to return the name of the TV. ✓ setPrice () method to reset the price of the TV. ✓ getPrice () method to return the price of the TV. ✓ display () method that prints out the class data. ✓ main () method to test the functionality of the class, asking the user to enter any necessary data. Note: the static data member (number) is set to 0 and it is increment by 1 when an object is instantiated.
