 ### Exercise 2.2
 * What value is returned if you check the machine’s balance after it has printed a ticket?

 ### Exercise 2.3
 * Experiment with inserting different amounts of money before printing tickets.
-	* Do you notice anything strange about the machine’s behavior?
+	* Do you notice anything strange about the machine’s behavior? I do not recieve a refund, nor do I have a remaining balance on my account.
 	* What happens if you insert too much money into the machine – do you receive any refund?
+    No refund.
 	* What happens if you do not insert enough and then try to print a ticket?
+    I can still print the 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?
+	* Does the printed ticket look different? 
+    No, it does not 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 {
+
+}
+
+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 it matters.
 
 * 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? 
+    Yes. The TicketMachine Class box has hash marks on it.
+	* What error message do you get when you now press the compile button? 
+    Error found in class. 
+	* Do you think this message clearly explains what is wrong? 
+    Yes, the hash marks show that it cannot be compiled.
 
 ### 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.
 
 ### 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.
+
+    methods: getPrice, getBalance, insertMoney, printTicket.
+    fields: price, balance, total, ticketNumber
+    constructor: TicketMachine
 
 ### Exercise 2.10
 * Do you notice any features of the constructor that make it significantly different from the other methods of the class?
+The constructor is the same name as the class.
 
 ### 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; Student
+private Server host; Server
 ```
 
 ### 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
 ```

+	* Does the appearance of the class diagram after each change give you a clue as to whether or not other orderings are possible? 
+    Yes, there are hash marks on the TicketMachine class box, and it is not possible to change the order.
 	* Check by pressing the compile button to see if there is an error message.
 	* Make sure that you reinstantiate the original version after your experiments!
 
 ### Exercise 2.14
 * Is it always necessary to have a semicolon at the end of a field declaration?
 * Once again, experiment via the editor.
+  Yes it is always necessary.
 * The rule you will learn here is an important one, so be sure to remember it.
 
 
 ### Exercise 2.15
 * Write in full the declaration for a field of type `int` whose name is `status`.
-
+  private int status;
 ### Exercise 2.16
 * To what class does the following constructor belong?
 ```
 public Student(String name)
 ```
+It belongs to the Student class.
 
 ### Exercise 2.17
 * How many parameters does the following constructor have and what are their types?
 ```
 public Book(String title, double price)
 ```
+This constructor has 2 parameters and they are of type String and type double.
 
 ### Exercise 2.18
 * Can you guess what types some of the `Book` class’s fields might be?
+The fields will likely be type String and type double.
 * Can you assume anything about the names of its fields?
-
+Two of the field names will likely be title and price.
