Create a TicketMachine object on the object bench and take a look at its methods. You should see the following: getBalance, getPrice, insertMoney, and printTicket. Try out the getPrice method. You should see a return value containing the price of the tickets that was set when this object was created. Use the insertMoney method to simulate inserting an amount of money into the machine. The machine stores as a balance the amount of money inserted. Use getBalance to check that the machine has kept an accurate record of the amount just inserted. You can insert several separate amounts of money into the machine, just like you might insert multiple coins or bills into a real machine. Try inserting the exact amount required for a ticket, and use getBalance to ensure that the balance is increased correctly. 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.
