JAVA- How do I update this code to add the new guidelines?

Add the following modifications to these two Java Files:

Now we are going to add to our Account Business Class. We need to add 2 methods:

1. deposit(amt); // adds the amt to the balance in the object and

// also updates the balance in the DB

1. withdraw(amt); //same as deposit above, except subtract

Account a1 = new Account();

//so to find an account in the database, call selectDB().

a1.selectDB(3001);

// so now to make a deposit we simply

a1.deposit(300.00);

// this method will display the new account balance

a1.display();

Part II Now build an AccountList Business Class. This class will have a list of Account Objects. You can use an Array or an ArrayList to store this list. I would also have a count property to keep track of how many Accounts are on the list. Methods should include a display() method, and an add (Account a1) method.

Part III Now add a new Property to the Customer class.

AccountList aList;

Make it so that when an User calls the selectDB(3001) method(and passes a custid), the Customer class will go look in the database for all accounts that belong to this customer and put them in the use the aList object. So the Customer class will contain a list of Accounts that the customer owns.

HINT: You do not need buttons for all the numbers 1,2,3,4,5,6,7,8,9,0. If you make your calculator like this, it becomes much more complex. Keep your calculator simple by following the instructions above.
