(New Account class) An Account class was specified in Programming Exercise 9.7. Design a new Account class as follows: 1 Add a new data field name of the String type to store the name of the customer. I Add a new constructor that constructs an account with the specified name, id, and balance. I Add a new data field named transactions whose type is ArrayList that stores the transaction for the accounts. Each transaction is an instance of the Transaction class, which is defined as shown in Figure I1.6.

Design a new Account class as follows:
New Account class
1 Add a new data field name of the String type to store the name of the
customer.
1 Add a new constructor that constructs an account with the specified name, id,
and balance.
I Add a new data field named transactions whose type is ArrayList that
stores the transaction for the accounts. Each transaction is an instance of the
Transaction class, which is defined as shown in Figure 11.6.
The get and sat methods for these data
fields are provided in the class, but omitted in the UML
diagram for brevity.
Transaction
-date: java. util.Date
The date of this transaction.
-type: char
The type of the transaction, such as "w for withdrawal.
*D" for deposit.
-amount: double
The amount of the transaction.
-balance: double
The new balance after this transaction.
