Take the tax program from the last homework assignment and implement it using classes and objects instead.
To do so, create a class definition for a class called Customer with attributes income and tax. It should also have a set method for income, and a calcTax() method to assign tax and return it. As a reminder, the tax is calculated as follows:
Income
Tax Due
$0 - $50,000
5%
$50,000-$100,000
$2,500 + 10% of (income > $50,000)
> $100,000
$7,500 + 15% of (income > $100,000)
Create a Customer object in main, have the user enter the income and assign this to the income variable of the Customer object, and then call the calcTax() method for the Customer object and print the tax due.
add a class to package that represents your new drivable type. That type should be something that is capable of being driven (speeding up and slowing down) and therefore a perfect candidate for a class that implements the actions in the Drivable interface.
In this challenge, we'll implement an Account class along with two derived classes, Savings and Current.
Problem Statement# Write a code that has:
● A parent class named Account.
○ Inside it define:
■ a protected double member balance
■ public void Withdraw(double amount)
■ public void Deposit(double amount)
■ public void printBalance()
● Then, there are two derived classes
○ Savings class
■ has a private member interestRate set to 0.8
■ Withdraw(double amount) deducts amount from balance with interestRate
■ Deposit(double amount) adds amount in balance with interestRate
■ printBalance() displays the balance in the account
○ Current class
■ Withdraw(double amount) deducts amount from balance
■ Deposit(double amount) adds amount in balance
■ printBalance() displays the balance in the account
Input#
● In the Savings class, balance is set to 50000 in the parametrized constructor
● In the Current class, balance is set to 50000 in the parametrized constructor
Output#
Balance before…
