A transport company wants to buy different type of vehicles through loan. So it needs a system to calculate the loan amount to pay for the different vehicles. Develop a java program to calculate total loan amount using concept of inheritance based on the following instructions. Save the file/project as TransportYourlD. A) Class name: Vehicle_yourFirstName Member variables: principalAmount, rate Member Method: parametrized constructor to initialize member variables - to calculate and return interest of vehicle interest = principalAmount * rate? B) Class name: LandTransport extends Vehicle_yourFirstName Member variables: noOfYear Member Method : - Constructor to invoke the constructor of the super class and initialize noOfYear - to calculate and return loan amount of Land Transport loanAmount = interest * ( ( noOfYear / 12) + 365) c) Controlling class : TransportYourID - To create object of class LandTransport - To display interest of Vehicle_yourFirstName - To display loan amount of LandTransport - To display noOfYear of LandTransport

Write a tester program to test the mobile class defined below. Create the class named with your id (for example: Id12345678) with the main method. Create two mobiles M1 and M2 using the first constructor. Print the characteristics of M1 and M2. Create one mobile M3 using the second constructor. Change the id and brand of the mobile M3. Print the id of M3. The programming I'm using is java. So, I'll be much appreciated if the answer was in java plus, Can you solve with the entry below? public class Mobile { private int id; private String brand; public Mobile() { id = 0; brand = ""; } public Mobile(int n, String name) { id = n; brand = name; } public void setBrand(String w) { brand = w; } public void setId(int w) { id = w; } Public int getId() { return id; } public String getBrand() { return brand; } }
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…
Write a program in java that contain a class named office, data members include area and noOfEmployees. Two classes named regionalOffice and headQuarters are derived from office. regionalOffice contain managerName and location as data members while headQuarters contain CEO as data member. Data members of child class must be protected. Write input method, display method, a parametric constructor initializing all data members(both parent and child class). Use chaining in above all. Also define all accessor and mutator methods
Use Java Code to create this: 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.
In Python 3, create a parent class named Machine and a child class named PollMachine. Have methods to clear the machine state, to agree or disagree with 3 polling questions of your choice, get tallies of all the agrees and disagrees for each answer, and display the results once the poll is ended (these methods can go in whichever class). Keep asking users to enter answers until the user ends the program. The program should use inheritance, so there should be a parent class and a child class.
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.

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.
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…
