 ### Exercise 2.1
-* Create a TicketMachine object on the object bench.
+* Create a TicketMachine object on the object bench. 
 * Upon viewing its methods, `getBalance`, `getPrice`, `insertMoney`, `printTicket`.
 * 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 2.2
 * What value is returned if you check the machine’s balance after it has printed a ticket?
+* The balance is $0.
 
 ### Exercise 2.3
 * Experiment with inserting different amounts of money before printing tickets.
-	* Do you notice anything strange about the machine’s behavior?
-	* What happens if you insert too much money into the machine – do you receive any refund?
-	* What happens if you do not insert enough and then try to print a ticket?
+    * Do you notice anything strange about the machine’s behavior?
+    * The machine continues to add that amount on to what I already paid. 
+
+    * What happens if you insert too much money into the machine – do you receive any refund?
+    * No, it moves the money to the Total.
+
+    * What happens if you do not insert enough and then try to print a ticket?
+    * The machine says that I need 500 cents and only entered 300.
 
 ### 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 2.5
 * Create another ticket machine for tickets of a different price.
-	* Buy a ticket from that machine.
-	* Does the printed ticket look different?
+    * Buy a ticket from that machine.
+    * Does the printed ticket look different?
+    * Only slightly, it just changes the print that the ticket costs.
 
 ### Exercise 2.6

 ### Exercise 2.8
 * Check whether or not it is possible to leave out the word `public` from the outer wrapper of the `TicketMachine` class.
+* It is possible because it allows me to compile and run the tests. 
 
 ### 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.
-	* Hint: There is only one constructor in the class.

+    * Fields - price, balance, total, ticketnumber, 
 
 ### Exercise 2.10
 * Do you notice any features of the constructor that make it significantly different from the other methods of the class?
+* Constructors must be named the same as the class and they cannot return anything.
 
 ### Exercise 2.11
 * What do you think is the type of each of the following fields?
