+\f0\fs24 \cf0 Exercise 2.2\
+\
+"Ticket price: 500 cents. Your total is 900."\
+\
+Exercise 2.3\
+\
+Yes the machine continues to take money, but never gives a ticket and it continues to add to the total. I do not receive a refund it continues to add on to the inserted money. It still adds to the total balance.\
+\
+Exercise 2.4\
+\
+I believe I have a good understanding\
+\
+Exercise 2.5\
+\
+No the code still doesn't look any different\
+\
+Exercise 2.6\
+\
+public class Student and public class LabClass\
+\
+Exercise 2.7\
+\
+Yes it does, the error message states the identifier is missing. Yes I notice the change in the class diagram.\
+No, I think the error message should clarify what is missing from the section like state the identifier as public or private.\
+\
+Exercise 2.8 \
+\
+It is possible to leave out the word public and keep running, but public is important for any other class to use the codes.\
+\
+Exercise 2.9\
+\
+Constructors do not return anything and are usually named after the public class name. Like TicketMachine in this example. Fields are any variables set equal to something, like balance = 0 or total = total + balance. Methods are any codes that have a return or will change something in the code. For example public string printTicket() is a method it will affect the total in the code and increase the ticket number.\
+\
+Exercise 2.10\
+\
+Yes, the constructor does not return any value.\
+\
+Exercise 2.11\
+Types are next to the private or public\
+Private int count; int\
+Private Student representative; Student\
+Private Server host; Server\
+\
+Exercise 2.12\
+Names are after the identifier\
+Private boolean alive; alive\
+Private Person tutor; tutor\
+Private Game game; game\
+\
+Exercise	2.13\
+\
+Yes, the private must be before int. There are error message it is missing the identifier\
+\
+Exercise 2.14\
+\
+Yes, you always need a semicolon	\
+\
+Exercise 2.15\
+\
+Private int status}

 * 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 2.2
-* What value is returned if you check the machine’s balance after it has printed a ticket?
+* What value is returned if you check the machine’s balance after it has printed a ticket? A higher value 
 
 ### Exercise 2.3
 * Experiment with inserting different amounts of money before printing tickets.
