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; } }
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…
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”
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?
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…
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.
public Account (double initialBalance){balance = initialBalance;}public Account () {balance = 0;}public void deposit (double amount){balance += amount; // Balance = balance + amount}public void withdraw (double amount){balance -= amount; // balance = balance - amount}public void close (){balance = 0;}public String toString(){return "balance: " + balance;}} Modify the Account class by adding two instance variables containing the customer's name and the account number. Both will be String objects. Modify the primary constructor for the Account class so that it takes three parameters: the balance, the customer's name, and the account number. Add instance methods named getCustomerName and getAccountNumber that return the customer name and account number.
Java A class always has a constructor that does not take any parameters even if there are other constructors in the class that take parameters. Choose one of the options:TrueFalse

This composition example contains classes Date, Employee and EmployeeTest .Class Date declares instance variables month, day and year to represent a date. The constructor receives three int parameters. It has method checkMonth to validate the month—if the value is out-of-range the method throws an error message. same goes for year and day. Provide getters, setters and toString method. Class Employee has instance variables firstName, lastName, birthDate and hireDate.Members firstName and lastName are references to String objects. Members birthDate and hireDate are references to Date objects. This demonstrates that a class can have as instance variables references to objects of other classes. The Employee constructor takes four parameters—first, last, dateOfBirth and dateOfHire. The objects referenced by the parameters are assigned to the Employee object’s instance variables. When class Employee’s toString method is called, it returns a String containing the employee’s name and the…

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
