- 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.public class Accumulator { private int total private String name; public Accummulator (string name , int total) { this .name = name; this .total=total; } } 3. In a main method, create an object of Accumulator with the name as "Mary" and total as 100.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.

Use a static variable annualInterestRate to store the annual interest rate for all account holders. Each object of the class contains a private instance variable principal indicating the amount the person is borrowing. Provide method: public double calculateMonthlyPayment(int numberOfPayments) to calculate the monthly payment by using the following formula: double monthlyPayment = principal * ( monthlyInterest / (1 - Math.pow(1 + monthlyInterest, -numberOfPayments))); where monthly interest = annualInterestRate/12. Provide a static method setAnnualInterestRate that sets the annualInterestRate to a new value. Set the initial loan amount (Principal) for a new loan through the constructor. Write a program to test class LoanAccount. Instantiate two LoanAccount objects, loan1 and loan2, with principal loan amounts of $5000.00 and $31000.00, respectively. Set annualInterestRate to 1%, then calculate the monthly…Create an automobile class that will be used by a dealership as a vehicle inventory program. The following attributes should be present in your automobile class: private string make private string model private string color private int year private int mileage Your program should have appropriate methods such as: default constructor parameterized constructor add a new vehicle method list vehicle information (return string array) remove a vehicle method update vehicle attributes method. All methods should include try..catch constructs. Except as noted all methods should return a success or failure message (failure message defined in "catch"). Create an additional class to call your automobile class (e.g., Main or AutomobileInventory). Include a try..catch construct and print it to the console. Call automobile class with parameterized constructor (e.g., "make, model, color, year, mileage"). Then call the method to list the values. Loop through the array and print to the screen.…
- THIS NEEDS TO BE DONE IN JAVA Modify the Account class to provide a debit method that withdraws money from an Account. Ensure that the debit amount does not exceed the Account's balance. If it does, the balance should be left unchanged and the method should print out a message indicating "Debit amount exceeded amount balance." Modify class AccountTest to test method debit. Below are links to the Account and AccountTest programs. //This is for the account class public class Account {private String name; //instance variableprivate double balance; //instance variable//Account constructor that receives two parameterspublic Account(String name, double balance){this.name = name; //assing name to instance varialbe name//validate that the balance is greater than 0.0; if it's not,//instance varisble balance keeps its default initial value of 0.0if (balance > 0.0){ //if the balance is valaidthis.balance = balance; //assign it to instance variable balance}}//method that deposits (adds)…7)Circle Class Write a Circle class that has the following fields: radius: a double PI:a final double initialized with the value 3.14159 The class should have the following methods: Constructor. Accepts the radius of the circles as an argument. Constructor. A no-arg constructor that sets the radius field to 0.0. setRadius. A mutator method for the radius field. getRadius.An accessor method for the radius field. area. Returns the area of the circle, which is calculated as area. Returns the area of the circles, which is calculated as area= PI * radius * radius diameter. Returns the diameter of the cirlce, which is calculated as diameter = radius * 2 circumference. Returns the circumference of the circle, which is calculated as circumference = 2 * PI * radius Write a program that demonstrates the Circle class by asking the user for the circles's radius, creating a Circle object, and then reporting the cirlce's area, diameter, and circumference.public class Artwork { // TODO: Declare private fields - title, yearCreated // TODO: Declare private field artist of type Artist // TODO: Define default constructor // TODO: Define get methods: getTitle(), getYearCreated() // TODO: Define second constructor to initialize // private fields (title, yearCreated, artist) // TODO: Define printInfo() method // Call the printInfo() method in Artist.java to print an artist's information }} public class ArtworkLabel { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); String userTitle, userArtistName; int yearCreated, userBirthYear, userDeathYear; userArtistName = scnr.nextLine(); userBirthYear = scnr.nextInt(); scnr.nextLine(); userDeathYear = scnr.nextInt(); scnr.nextLine(); userTitle = scnr.nextLine(); yearCreated =…
- Create a class called Jug that represents a jug of liquid. The UML for this class is shown below: Jug private String liquidType private int gallons public Jug public Jug(String type, int gal) public void setGallons() public void getGallons() public String getLiquidType() public boolean isEmpty() Your class should have the following private state: liquidType (a string) gallons (an integer) Your class should have the following constructors: A default constructor that creates an empty jug of water. A constructor that accepts the type of liquid the jug contains, and the number of gallons the jug contains, in that order. Your class should have the following behaviors: A method called setGallons that allows you to set the number of gallons in the jug. A method called getGallons that allows you to get the number of gallons in the jug. A method called getLiquidType that allows you to get the type of liquid in the jug. A method called isEmpty that returns true if the…IN JAVA PLEASE Child Class: Vegetable Write a child class called Vegetable.
