Problem Account Class You are a programmer for the Home JMSB

Problem Account Class You are a programmer for the Home JMSB Bank. You have been assigned to develop a class that models the basic workings of a bank account. The class should have the following properties Balance Holds the current account balance IntRate Interest: Holds the interest earned for the current period. Transactions: Holds the number of transactions for the current period. Holds the interest rate for the period. Write at least three constructors. Include properties for each of the data items. Create a second class that instantiates the first class with information about your account The class should also have the following methods MakeDeposit Takes an argument, which is the amount of the deposit. This argument is added to the Balance property Another method to Display transaction and Display the new balance Sample run JMSB Bank Current Account Details Transaction Number: 3 Current Balance : 1000 .00 Interest Rate: 6.15 Interest Earned: 150.00 Make Deposit Deposit: 100.00 New Balance: 1100.0e Press any key to go to the Account Update Calulator

       this.balance=balance;      
       this.intRate=intRate;
       this.transactions=transactions;

   //Returns string representation of Account object

Sample Output:

Transaction Number :3
Current Balance: 1000.0
Interest Rate :0.15
Interest Earned :150.0

Make Deposit
Deposit: 100.0
New Balance: 1100.0
