[Solved]Java 9 Bankaccount Savingsaccount Classes Design Abstract Class Named Bankaccount Hold Fol Q37221496

JAVA

9. BankAccount and SavingsAccount Classes Design an abstractclass named BankAccount to hold the following data for a bankaccount:

• Balance

• Number of deposits this month

• Number of withdrawals

• Annual interest rate

The class should have the following methods:

Constructor:

The constructor should accept arguments for the balance andannual interest rate.

deposit:

A method that accepts an argument for the amount of the deposit.The method should add the argument to the account balance. Itshould also increment the variable holding the number ofdeposits.

withdraw:

A method that accepts an argument for the amount of thewithdrawal. The method should subtract the argument from thebalance. It should also increment the variable holding the numberof withdrawals.

calcInterest:

A method that updates the balance by calculating the monthlyinter-est earned by the account, and adding this interest to thebalance. This is performed by the following formulas:

Monthly Interest Rate = (Annual Interest Rate / 12)

Monthly Interest = Balance * Monthly Interest Rate

Balance = Balance + Monthly Interest

monthlyProcess: A method that calls thecalcInterest method, and then sets the variables that hold thenumber of withdrawals, number of deposits to zero.

Next, design a SavingsAccount class that extends the BankAccountclass. The SavingsAccount class should have a status field torepresent an active or inactive account. If the balance of asavings account falls below $25, it becomes inactive. (The statusfield could be a boolean variable.) No more withdrawals may be madeuntil the balance is raised above $25, at which time the accountbecomes active again.

The savings account class should have the following methods:

withdraw: A method that determines whether theaccount is inactive before a withdrawal is made. (No withdrawalwill be allowed if the account is not active.) A withdrawal is thenmade by calling the superclass version of the method.

After the superclass method is called, this method checks thenum-ber of withdrawals. If the number of withdrawals for the monthis more than 4, a service charge of $1 for each withdrawal above 4is from the balance. (Don’t forget to check the account balanceafter the service charge is taken. If the balance falls below $25,the account becomes inactive.)

deposit: A deposit is then made by calling thesuperclass version of the method. If the account is inactive andthe deposit brings the balance above $25, the account becomesactive again.

monthlyProcess:

Calls the super class monthly process and displays the finalbalance.
