Use Java Programming Language
Create a Loan Account Hierarchy consisting of the following classes: LoanAccount, CarLoan, PrimaryMortgage , UnsecuredLoan, and Address. Each class should be in it's own .java file.
The LoanAccount class consists of the following properties:
- principal- the original amount of the loan.
- annualInterestRate - the annual interest rate for the loan. It is not static as each loan can have it's own interest rate.
- months - the number of months in the term of the loan, i.e. the length of the loan.
and the following methods:
- a constructor that takes the three properties as parameters.
- calculateMonthlyPayment() - takes no parameters and calculates the monthly payment using the same formula as Assignment 1.
- getters for the three property variables.
- toString() - displays the information about the principle, annualInterestRate, and months as shown in the example output below.
The CarLoan class which is a subclass of the LoanAccount class and consists of the following property:
- vehicleVIN - the VIN number of the car, as a string.
and the following methods:
- constructor that accepts the three parameters of the LoanAccount class and the vehicleVIN.
- toString() - displays the information about the VIN number as shown in the example output below.
The PrimaryMortgage class which is a subclass of LoanAccount and consists of the following properties:
- PMIMonthlyAmount - the amount of the Primary Mortgage Insurance which is required for all mortgages where the down payment is not at least 20% of the home value.
- Address - the address of the real estate and is an object of the Address class.
and the following methods:
- constructor that accepts the three parameters of the LoanAccount class, the PMIMonthlyAmount, and the Address object containing the address.
- toString() - displays the information about the PMIMonthlyAmount and Address as shown in the example output below.
The UnsecuredLoan class which is a subclass of LoanAccount and has no additional properties and has the following methods:
- constructor that accepts the three parameters of the LoanAccount class.
- toString() - displays the information that it is an Unsecured Loan as shown in the example output below.
The Address class which consists of the following properties:
- street - the house number and street part of the address.
- city - the city where it is located.
- state - the state.
- zipcode - and the zipcode.
and the following methods:
- constructor which accepts the values for the four properties as parameters.
- getters for each property.
- toString() - display the address information as shown in the example below.
Your code in the subclasses should call methods in the super classes whenever possible to reduce the amount of code in the subclasses and utilize the code already developed in the super classes.
Use the following code in your main function to test your classes, just copy and paste it into your main method:
// Create three different loan objects, one of each type.
CarLoan carLoan = new CarLoan(25000.00, 4.25, 72, "IRQ3458977");
Address propertyAddress = new Address("321 Main Street", "State College", "PA", "16801");
PrimaryMortgage propertyLoan = new PrimaryMortgage(250000.00, 3.1, 360, 35.12, propertyAddress);
UnsecuredLoan unsecuredLoan = new UnsecuredLoan(5000.00, 10.75, 48);
//Print out the load information for each loan using the toString() method.
System.out.format("%n%s%s%s%n", carLoan, propertyLoan, unsecuredLoan);
CarLoan carLoan = new CarLoan(25000.00, 4.25, 72, "IRQ3458977");
Address propertyAddress = new Address("321 Main Street", "State College", "PA", "16801");
PrimaryMortgage propertyLoan = new PrimaryMortgage(250000.00, 3.1, 360, 35.12, propertyAddress);
UnsecuredLoan unsecuredLoan = new UnsecuredLoan(5000.00, 10.75, 48);
//Print out the load information for each loan using the toString() method.
System.out.format("%n%s%s%s%n", carLoan, propertyLoan, unsecuredLoan);
The output from your program should look like the following:
run:
Car Loan with:
Principal: $25000.00
Annual Interest Rate: 4.25%
Term of Loan in Months: 72
Monthly Payment: $393.98
Vehicle VIN: IRQ3458977
Primary Mortgage Loan with:
Principal: $250000.00
Annual Interest Rate: 3.10%
Term of Loan in Months: 360
Monthly Payment: $1067.54
PMI Monthly Amount: $35.12
Property Address:
321 Main Street
State College, PA 16801
Unsecured Loan with:
Principal: $5000.00
Annual Interest Rate: 10.75%
Term of Loan in Months: 48
Monthly Payment: $128.62

- Portfolio Instructions: You are working for a financial advisor who creates portfolios of financial securities for his clients. A portfolio is a conglomeration of various financial assets, such as stocks and bonds, that together create a balanced collection of investments. When the financial advisor makes a purchase of securities on behalf of a client, a single transaction can include multiple shares of stock or multiple bonds. It is your job to create an object-oriented application that will allow the financial advisor to maintain the portfolios for his/her clients. You will need to create several classes to maintain this information: Security, Stock, Bond, Portfolio, and Date. The characteristics of stocks and bonds in a portfolio are shown below: Stocks: Bonds: Purchase date (Date) Purchase date (Date) Purchase price (double)…arrow_forwardComputer programmingarrow_forwardExercise 1-Account class • Design a class named Account that contains : • A private int data field named id for the account • A private double data field named balance for the account • A privet Date data field named dateCreated that stores the date when the account was created • A no-arg constructor that creates a default account • A constructor that creates an account with the specified id and initial balance • The getters (i.e., accessors) and setters (i.e., mutators) methods for id and balance • The getter method for dateCreated • A method named withdraw that withdraws a specified amount from the account • A method named deposit that deposits a specified amount to the accountarrow_forward
