- Task Write a class named Account to represent an account that you may find at a bank. Accounts have a balance and an annual interest rate. Include attributes in the Account class to reflect these. Write getters for both attributes and a setter for only the annual interest rate. Think about how real bank accounts work, you change your balance by withdrawing and depositing money, not just by telling the banker how much you want to change it to. Include a constructor with parameters used to assign values to both attributes. Users should be able to withdraw money from an Account, deposit money into an Account, find monthly interest rate, and find monthy interest. Include methods for each of these actions. More details on them below. withdraw method This method simulates withdrawing money from the Account. It should not return a value and take the amount to withdraw as a parameter and reduce the balance by this amount. deposit method This method simulates depositing money into the Account.…Design a class called "Person" with attributes for name, age, and gender. Implement methods to get and set these attributes, and also a method to calculate the person's age in dog years (assuming 1 dog year is equivalent to 7 human years).Please use Java to help me with the assignment below. The assignment: A microwave control panel has four buttons: one for increasing the time by 30 seconds, one for switching between power levels 1 and 2, a reset button, and a start button. Implement a class that simulates the microwave, with a method for each button. The method for the start button should print a message “Cooking for ... seconds at level ...”.
- In this activity, we are going to plan out and write a class definition that stores information for a book. Let's say we want to store the following information about this book: The book's name The book's author(s) (a book can have more than one author) The book's publisher The book's ISBN number The book's price The book's year of publication First, answer the following questions before the design: 1. What is a suitable name for this class? (Pick a name that best describes it).Write code for an Invoice class for a car sale. Printing an object of the Invoice should print thedetails about the seller, the buyer, the dealer, the date of transaction, the car being sold, the purchase andselling price, the commission earned by the dealer, sales tax, and the total price of the car (calculated giventhe details in Question 3 part 3). A generation of the invoice object should set the isSold variable of the car class to true. You do not need to write code for any other classes import java.io.File;import java.io.FileWriter;import java.io.IOException; abstract class Car { // class car String[] name; int reg_number, eng_number, chassis_num, status; String[] city, model, color, date_reg, date_arr, type; float price; abstract float calculate(float price);} class Dealer extends Car { // inherits from Car String[] deal_name, deal_id, deal_add, deal_pno; float dealer_com; float calculate(float price) { dealer_com = (float) (0.01 * price + 0.01 * price); // adding extra 2%…Write code for an Invoice class for a car sale.

- Respond to what is asked: Write a constructor in the Car class given below that initializes the attribute brand with the string “Ford” and the attribute color to “red”. Construct a getColor() This method returns the color of the car Construct setter methods for the 2 attributes. In the main program, create one car object then display the brand and color of the car. Change the initial values of these attributes using the setter methods: brand is BMW, color is black Display the changes of values of these attributes. Create an array of 3 cars, whose initial values are the one set by the constructor. Display the values of the attributes of these 3 objects.. The class Car class Car { String brand; String color //your constructor here public String getBrand() { return brand; } void run() {…Design a class that holds the following personal data: name, address, age, and phone number. Write appropriate accessor and mutator methods. Also, design 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. very basic ALGORITHM in PSUEDOCODE NOT PYTHON. Use fictitious information.Create a UML Diagram for this problem. Design a class named Rectangle to represent a rectangle. The class contains: i. Two data fields named width and height. ii. A constructor that creates a rectangle with the specified width and height. iii. A method named getArea() that returns the area of this rectangle. iv. A method named getPerimeter() that returns the perimeter. Write a test program that creates two Rectangle objects—one with width 4 and height 40 and the other with width 3.5 and height 35.7. Display the width, height, area, and perimeter of each rectangle in this order.
- Design a class called Stopwatch. The job of this class is to simulate a stopwatch. It should provide two methods: Start and Stop. We call the start method first, and the stop method next. Then we ask the stopwatch about the duration between start and stop. Duration should be a value in TimeSpan. Display the duration on the console. We should also be able to use a stopwatch multiple times. So we may start and stop it and then start and stop it again. Make sure the duration value each time is calculated properly. We should not be able to start a stopwatch twice in a row (because that may overwrite the initial start time). So the class should throw an InvalidOperationException if its started twice. 1In this assignment, you will need to design and implement a class Country (Country.java) that stores the name of the country, its population, and its area. Then write a program (LargestCountry.java) that reads countries from a “coutrydata.txt” and prints • The country with the largest area. • The country with the largest population. • The country with the largest population density (people per square mile). To make it concrete, the followings are the suggested tasks you need to perform: 1.1 Country Class In the first file Country.java, create a class named Country that models a country. It should contain at least the followings (However, you can add any other methods if you like): • Private instance variables name, population, and area; • A constructor takes all three inputs (the name, population and area); • Three getter methods to return each of three instance variables (accessor method); • One getter method to return country population density (accessor method); • Three setter…Create a class circle class with radius as data member. Create two constructors (no argument, and two arguments) and a method to calculate Circumference.
