Hello this is hw the over draft is calculated for the first over draft is 20 but for the second over draftand all other after that is 30 dollars. Yes then output show here has a miscalculation because there was a bug in the output or so he said, but is supposeto be like that. He also, sai is a short code t be ableto finish this. This is your program's required output. Notice how the first overdraft has a penalty of $20, but the second and third overdrafts have penalties of $30 each.

Hello, I really appreciate if someone can help me solve this exercise correctly. Thanks a lot in advance.

Complete Exercise E9.3 (checking account problem).

What to turn in: A zip file containing ONLY 3 java source code.files (BankAccount.java, BudgetCheckingAccount.java, and CheckingAccount.java). NO FOLDERS may be included in your zip file, or I will simply reject it. You are not giving me the AccountDemo.java file, because I have my own copy, and you are not permitted to modify it. Also, the package statement must be correct, as explained later in the assignment description.

You have to do it a bit differently from the way described in the book. Create a new subclass named BudgetCheckingAccount that extends CheckingAccount, and override the withdrawal method to implement the penalty mentioned in the exercise specification. Also, prevent the actual withdrawal from creating a negative balance. (The penalty, on the other hand CAN create a negative balance.) YOU ARE NOT PERMITTED TO MODIFY THE CheckingAccount class. (Companies often sell you their code library without giving you access to the source code.) Of course, you will have to make appropriate changes to the startup class, named AccountDemo. DO NOT MODIFY IT, not even the package statement!

Right-click to download a ZIP file (named Asg 2 start.zip) containing the classes you need for this assignment.

Make sure all our .java files have this statement on the first line:

package ch09.exercises_E9_3;
