 * 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?
-
+ I got the value 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?

+      - it still was the same no matter how much I put in
 
 ### 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?

 ### Exercise 2.6
 * Write out what you think the outer wrappers of the `Student` and `LabClass` classes might look like – do not worry about the inner part.
+public class Student{

 Does it matter whether we write<br>
 `public class TicketMachine`<br>
 or<br>
 `class public TicketMachine`<br>
 in the outer wrapper of a class?
-
+ it gave me an error
 * Edit the source of the `TicketMachine` class to make the change and then close the editor window.

 ### Exercise 2.8
 * Check whether or not it is possible to leave out the word `public` from the outer wrapper of the `TicketMachine` class.
-
+    no syntax error
 ### 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.
