Complete the Car class below so that it inherits from the given Vehicle class. Cars lose value over time. In this example, you should assume that the value is reduced by 25 cents per mile driven, until it reaches zero. Do not add any instance variables to the Car class. /** Represents a car.*/public class Car // TODO: Inherit from Vehicle{ // Do NOT add any instance variables public Car(double purchasePrice) { // TODO: Complete } // TODO: Override the getValue method}
using jave: Create the a Person class with the following: Class Variables:String firstname String lastname int birthmonth int birthday int birthyear String ssn (All variables above should be private) Constructor The main constructor should take in all values and assign them to their respective private class variables MethodsCreate a public getters and setters for firstname and lastname and SSN getFirstname getLastname setFirstname setLastname Create a public getter method called getBirthdate, which will return a String composed of their birthday in month/day/year format. For example, if birthmonth=3, birthday=22, birthyear=2000, it should return the String "3/22/2000" Create a public method called verifySSN that takes in a String parameter and returns a boolean. It will check the parameter against the person's SSN and return true or false based on whether they match.
The BankAccount class described below is used to represent a personal savings account with a yearly interest rate, (represented as a percentage, e.g., a 7% rate is represented by .07). The interest is applied monthly, (i.e., at the end of each month 1/12 of the interest is deposited into the account). public class BankAccount { public BankAccount(double rate) public BankAccount(double initBal, double rate) public double getBalance() public double getIntRate() public void setIntRate(double rate) public void deposit(double amount) public void withdraw(double amount) public void addMonthsInterest() private double balance; private double intRate; } Suppose a bank offers to its special customers a new type of savings account, called a “Credit Account”, that allows the customer to withdraw extra money if needed, so that the account balance is allowed to be negative at some times. These accounts award interest at the end of every month, as long as the balance is positive. If the…
Define the classbankAccountto store a bank customer’s account number and balance. Suppose that account number is of type int, and balance is of type double. Your class should, at least, provide the following operations: set the account number, retrieve the account number, retrieve the balance, deposit,and withdraw money, and print account information. Add appropriate constructors. b.Every bank offers a checking account. Derive the class checkingAccountfrom the classbankAccount(designed in parta). This classinherits members to store the account number and the balance from the base class. A customer with a checking account typically receives interest, maintains a minimum balance, and pays service charges if the balance falls below the minimum balance. Add member variables to store this additional information. In addition to the operations inherited from the base class, this class should provide the following operations: set interest rate, retrieve interest rate, set minimum balance,…
Look at the following partial class definition, and then respond to the questions that follow it: public class Student { private String Name; private String ID; private String Email; } a. Write a constructor for this class. The constructor should accept an argument for each of the fields. b. Write a ‘sendEmail” method, that takes one argument of character type called Grade. This method should print output to screen as below replacing the variable with actual values: Dear ‘Name’, You have received grade ‘Grade’. This email is being sent to your email address at “Email”
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 the board game Scrabble, each tile contains a letter, which is used to spell words in rows and columns, and a score, which is used to determine the value of words. The point of this exercise is to practice the mechanical part of creating a new class definition: Write a definition for a class named Tile that represents Scrabble tiles. The instance variables should be a character named "letter" and an integer named "value". Write a constructor that takes parameters named letter and value, and initializes the instance variables. Create getters for both of the attributes. (No setters, so that a Tile is immutable.) Implement the .toString() and .equals methods for a Tile. Your completed Tile class should work with this Main program (Links to an external site.) so that it produces sample output like shown at the end of the program. You can Fork the program to make your own version in Replit, where you can add your Tile.java, or you can copy the program to your own Java development…

CLASS AND OBJECT WRITE! 1.) Write the main class of the given class Animal below that set the number of legs to “4” and display (get) the number of legs. class Animal { private int numberOfLegs; public void setNumberOfLegs(int numberOfLegs) { this.numberOfLegs = numberOfLegs; } public int getNumberOfLegs() { return numberOfLegs; } }
Create two public classes: Mammal and Bird. Each should inherit from the Animal class shown below. For each new class, override the giveBirth method to produce the following output: For the Mammal class, the method should return: "I give live birth" For the Bird class, the method should return "I lay eggs" class Animal: """This is an animal""" def giveBirth(self): """Return the birthing method""" return "I don't know how"
