 * Use `getPrice` method to view the value of the price of the tickets that was set when this object was created.
 * Use `insertMoney` method to simulate inserting an amount of money into the machine.
 * Use `getBalance` to check that the machine has a record of the amount inserted.
-	* You can insert several separate amounts of money into the machine, just like you might insert multiple coins or notes into a real machine. Try inserting the exact amount required for a ticket. As this is a simple machine, a ticket will not be issued automatically, so once you have inserted enough money, call the `printTicket` method. A facsimile ticket should be printed in the BlueJ terminal window.

 ### Exercise 2.3
 * Experiment with inserting different amounts of money before printing tickets.

-	* What happens if you insert too much money into the machine – do you receive any refund?

 ### Exercise 2.4
 * Try to obtain a good understanding of a ticket machine’s behavior by interacting with it on the object bench before we start looking at how the `TicketMachine` class is implemented in the next section.

 ### Exercise 2.9
 * From your earlier experimentation with the ticket machine objects within BlueJ you can probably remember the names of some of the methods – `printTicket`, for instance.
-	* Look at the class definition in Code 2.1 and use this knowledge, along with the additional information about ordering we have given you, to try to make a list of the names of the fields, constructors, and methods in the `TicketMachine` class.
