JAVA

Create class SavingsAccount. 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 savingsBalance indicating the amount the saver currently has on deposit. Provide method calculateMonthlyInterest to calculate the monthly interest by multiplying the savingsBalance by annualInterestRate divided by 12 this interest should be added to savingsBalance. Provide a static method modifyInterestRate that sets the annualInterestRate to a new value. Write a program to test class SavingsAccount. Instantiate two savingsAccount objects, saver1 and saver2, with balances of $2000.00 and $3000.00, respectively. Set annualInterestRate to 4%, then calculate the monthly interest and print the new balances for both savers. Then set the annualInterestRate to 5%, calculate the next months interest and print the new balances for both savers.

a) Create a super class called Car. The Car class has the following fields and methods:

Int speed;

double regularPrice;

String color;

double getSalePrice();

int length;

double getSalePrice();

* If length > 20 feet, 5% discount, Otherwise, 10% discount.

e) Create MyOwnAutoShop class which contains the main() method. Perform the following within the main() method:

Create an instance of Sedan class and initialize all the fields with appropriate values. Use super(...) method in the constructor for initializing the fields of the superclass.
