 * 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?
 
+- Balance was cleared and is 0. Added to machine's total
+
 ### 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?
+    * -Machine prints tickets if method is run even if balance isnt enough to cover ticket price. Money added to total
+    * 
+    * What happens if you insert too much money into the machine – do you receive any refund?
+    * -The machine collects all the money in total with no refund
+    * 
+    * What happens if you do not insert enough and then try to print a ticket?
+    * It always prints a ticket and adds balance to total. Does not make any checks to see if balance amount is enough.
 
 ### 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? 
+    * -Different ticket price on the second machine compared to first
 
 ### 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?
 
+-Yes because it means that the class can used by other classes in the code. if class is before public then it wont be able to be used by other classes.
+
 * 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 color diagram no longer continued as soon as we swapped it
+    * What error message do you get when you now press the compile button? Unexpected identifier
+    * Do you think this message clearly explains what is wrong? No not really. I believe java is looking for a class after public and cannot find one.
 
 ### 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. code still compiles
 ### 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.

+    * Hint: There is only one constructor in the class.
+    * 
+    * fields - balance, total, ticket number
+    * constructor - ticket price
+    * methods -  insertMoney(), getBalance(), printTicker(), getPrice()
+    * 
 
 ### Exercise 2.10
 * Do you notice any features of the constructor that make it significantly different from the other methods of the class?
+* Its asked for first when creating an object and doesnt affect any other method. Other methods return values to each other. Ticket price is never checked
 
 ### Exercise 2.11
 * What do you think is the type of each of the following fields?
 
 ```java
-private int count;
+private int count; 
 private Student representative;
 private Server host;
 ```
 
+interger
+string
+string
+
 ### Exercise 2.12
 * What are the names of the following fields?
 
 ```java
-private boolean alive;
+private boolean alive; 
 private Person tutor;
 private Game game;
 ```
+
+alive
+tutor
+game
 ### Exercise 2.13
 
 In the following field declaration from the TicketMachine class<br>
 
 ```java
-private int price;
+price private int price;
 ```
 does it matter which order the three words appear in?
+
 * Edit the `TicketMachine` class to try different orderings. After each change, close the editor.
-	* Does the appearance of the class diagram after each change give you a clue as to whether or not other orderings are
+    * Does the appearance of the class diagram after each change give you a clue as to whether or not other orderings are
 possible?
-	* 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!

+    * 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!
+-Unexpected idenifier again or illegal start of type
+
 ### Exercise 2.14
-* Is it always necessary to have a semicolon at the end of a field declaration?
+* Is it always necessary to have a semicolon at the end of a field declaration? 
 * Once again, experiment via the editor.
 * The rule you will learn here is an important one, so be sure to remember it.
+* 
+-Yes otherwise the code will continue to keep reading past where it should stop .
 
 
 ### 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)
 ```
+-Student
+
 
 ### Exercise 2.17
 * How many parameters does the following constructor have and what are their types?
 ```
 public Book(String title, double price)
 ```
 
+2
+title is a string
+price is a double
+
 ### Exercise 2.18
 * Can you guess what types some of the `Book` class’s fields might be?
 * Can you assume anything about the names of its fields?
 
+name - string
+page number - integer
+price - double
+chapter number - integer
+date published - integer
+is digital or ebook - boolean
+
