BankAccount toString
Add a toString method to the BankAccount class.
Your method should return a string that contains the account's name and balance separated by a comma and space.
For example, if an account object named benben has the name "Benson" and a balance of 17.25, benben.toString() should return:
Benson, $17.25
If the client code were to call System.out.println(benben); , that text would be shown on the console.
(Test your code by writing a short client program that constructs and initializes an account, then prints it.)
