Challenge 3: Implement an Account Class using Polymorphism

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 withdrawing from the savings account Balance after withdrawing from the savings account

Balance before withdrawing from the current account Balance after withdrawing from the current account

Sample Input

    // creating savings account object
    Account SAccount = new Savings(50000);
    
    SAccount.Deposit(1000);
    SAccount.printBalance();

    SAccount.Withdraw(3000);
    SAccount.printBalance();

    System.out.println();

    // creating current account object
    Account CAccount = new Current(50000);
    CAccount.Deposit(1000);
    CAccount.printBalance();

    CAccount.Withdraw(3000);
    CAccount.printBalance();  

Sample Output

    Balance in your saving account: 51800.0
    Balance in your saving account: 46400.0

    Balance in your current account: 51000.0
    Balance in your current account: 48000.0
