 ### Exercise 2.2
 * What value is returned if you check the machine’s balance after it has printed a ticket?
-
+its 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? 
+	* What happens if you insert too much money into the machine – do you receive any refund? It takes all your money and gives no change or refund
+	* What happens if you do not insert enough and then try to print a ticket? It still prints a ticket

 ### 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?
-
+	yup
 ### 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
+{
+}
+
+public class LabClass
+{
+}

 ### Exercise 2.7
 Does it matter whether we write<br>
 `public class TicketMachine`<br>
 or<br>
 `class public TicketMachine`<br>
-in the outer wrapper of a class?
+in the outer wrapper of a class? yes, we get a compiler error if it is in the wrong order.
 
 * Edit the source of the `TicketMachine` class to make the change and then close the editor window.
-	* Do you notice a change in the class diagram?
-	* What error message do you get when you now press the compile button?
-	* Do you think this message clearly explains what is wrong?
+	* Do you notice a change in the class diagram? yup
+	* What error message do you get when you now press the compile button? <identifier> expected
+	* Do you think this message clearly explains what is wrong? kinda
 
 ### 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 posssible but i dont know why there is 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.
+	fields: 1. price
+		2. balance
+		3. total
+		4. ticketNumber
+	constructers: 
+		1. TicketMachine(Integer ticketCost)
+	methods:1. calculateTotal()
+		2. getBalance()
+		3. getPrice()
+		4. getTicketNumber()
+		5. incrementTicketNumber()
+		6. insertMoney()
+		7. printTicket()
 
 ### Exercise 2.10
 * Do you notice any features of the constructor that make it significantly different from the other methods of the class?
-
+It has the same name as the class. It doesn't return a value
 ### Exercise 2.11
 * What do you think is the type of each of the following fields?
 
 ```java
-private int count;
-private Student representative;
-private Server host;
+private int count; int
+private Student representative; String
+private Server host; String
 ```
 
 ### Exercise 2.12
 * What are the names of the following fields?
 
 ```java
-private boolean alive;
-private Person tutor;
-private Game game;
+private boolean alive; alive
+private Person tutor; tutor
+private Game game; game
 ```
