Part $1$: Implement a superclass BankAccount that has the following fields and methods.

Fields:

string firstName

string lastName

int accountID

double balance

Methods:

constructor$()$: initialize balance to zero

deposit$()-$ will accept a single value double parameter; the parameter value is added to the existing balance

withdrawal$()-$ accepts a single value double dollar amount; the parameter value is subtracted from the existing balance

Setters and getters for firstName, lastName, and accountID

getBalance$()$ getter to return the balance

accountSummary$()-$ prints all account information

Part $2$: Implement a CheckingAccount class that inherits from the BankAccount class, that:

Has an interest rate attribute

Allows overdraft withdrawals and charges a $$30$ fee

Methods:

processWithdrawal$()-$ will display a negative balance that includes a $$30$ overdraft fee and denotes that a fee has been accessed

displayAccount$()-$ should display all superclass attributes and provides an additional interest rate

Ensure that your program has the two required classes and a test class.

Place each Java class into a separate Java source file.N
