- 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…CSC 1302: PRINCIPLES OF COMPUTER SCIENCE II Lab 6 How to Submit Please submit your answers to the lab instructor once you have completed.

Assume both radius and height are global instance variables declared as double. public double calcVolume() { return Math.PI * radius * radius * height; } You decide that a static method (also called calcVolume) for calculating volume (of a theoretical cylinder) might be useful to client coders. Write the static method. Then rewrite the instance method shown above to leverage the new static method (thus reducing code duplication).
