CS220-Project 5 Inheritance and Abstract Classes Solved

This project extends the previous one and is designed for you to practice inheritance and abstract classes.
Same as the last project, you will write a program that allows a user to repeatedly create and manage express card accounts. However, we will add a type for each express card account. There are two types of express card accounts: a student express account or a faculty express account. All express account have fields accountNumber , accountBalance , numberOfMeals , pricePerMeal , baseAmtForBonus and accountTypeName .
Some changes for an express account are listed below:
• The criteria of receiving bonus for these two types of express accounts are different:
– The baseAmtForBonus is set to $500.0 for a student express account.
– The baseAmtForBonus is set to $0.0 for a faculty express account in the corresponding constructor.
• rewardLevel and rewardAmt are two variables only for a student express account for bonus receiving bonus. Same as in the previous project, for every deposit that is greater than the baseAmtForBonus , for each rewardLevel , a student account receives rewardAmt amount of money. For example, if rewardLevel is set to 200.0 and rewardAmt is set to 2.0, then a deposit of $500 to a $0 balance student express account will result $4.0 bonus and a new balance of $504.0. However, a deposit of $499 to a $100 balance student express account will not obtain any bonus and final balance is $599.0.
The variable rewardLevel should be set to $200.0 and rewardAmt to $2.0. While we won’t change the value of them in this project, they must be variables.
• A faculty express account has only one extra variable for bonus: rewardPct , the percentage of deposit that will become the bonus. In this project, it is set to 0.01. For example, since the baseAmtForBonus is $0.0 for a faculty, a $50 deposit to a $0 balance faculty express account will
result $0.5 bonus and a new balance of $50.5.
• The pricePerMeal is $8.0 for a faculty account and $10.0 for a student.
With the above changes, when creating a new account, your program should ask the use to choose which type of the new account s/he wants to create. If the user chooses a student express account, then all the headers displayed in the sub-menu should be of the form “STUDENT EXPRESS ACCOUNT #0, BALANCE: $0.0, NUMBER OF MEALS: 0”. Otherwise, the headers displayed in the sub-menu should be of the form “FACULTY EXPRESS ACCOUNT #0, BALANCE: $0.0, NUMBER OF MEALS: 0”.
Implementation Hints
• Start from the ExpressAccount class that you have written from the previous project, remove rewardLevel and rewardAmt fields and corresponding methods from this class.
• Implement classes for the student and faculty express accounts that extend the ExpressAccount and implement the appropriate behavior for each type of account. These subclasses should reuse as much as possible from the base ExpressAccount class. If functionality is shared between both account types, then it should be included in the ExpressAccount class (i.e., don’t implement the same thing three times in the subclasses, implement it once in the ExpressAccount class). You may add constructors and protected setters to your ExpressAccount class; however, you should be able to reuse the methods purchaseMeal and haveMeal implemented in your ExpressAccount class.
• Same as before, you have two levels of menu: main menu and sub-menus. For each option in the main menu, there is a sub-menu for this option. However, when the user chooses to create a new account, your program should print out a sub-menu that asks the user to choose a type of the account.
• After you are done with the implementation, make sure you clean up your code. Remove unnecessary testing code and comments.
• All source files should include a description header, be properly indented and commented.
Code Skeleton
Your final java source code should include the following classes:
• ExpAcct.java : This is where your main method will be. It contains the whole logic of the application.
• ExpressAccount.java : This is the super class that contains the common properties and behaviors of the classes FacultyExpressAccount and StudentExpressAccount .
• FacultyExpressAccount.java
• StudentExpressAccount.java
Part of the code skeleton is shown as follows:
public class ExpAcct {
. . . . . .
public static void main( String [ ] args ) {
. . . . . .
}
}
public abstract class ExpressAccount {
. . . . . .
public ExpressAccount ( int accNumber) {
. . . . . .
}
public int getAccountNumber () {
. . . . . .
}
public double getAccountBalance () {

}
public double getBaseAmtForBonus () {
