 Work through all these exercises. You edit this file with your answers for these exercises.
 
-* Exercise 2.1 Create a TicketMachine object on the object bench and take a look
-at its methods. You should see the following: getBalance, getPrice, insertMoney,
-and printTicket. Try out the getPrice method. You should see a return value containing
-the price of the tickets that was set when this object was created. Use the
-insertMoney method to simulate inserting an amount of money into the machine and
-then 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?
-* 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?
-* 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?
-
-* 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.
-* Exercise 2.7 Does it matter whether we write
-`public class TicketMachine`
-or
-`class public TicketMachine`
-in the outer wrapper of a class? 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?
-* Exercise 2.8 Check whether or not it is possible to leave out the word public
-from the outer wrapper of the TicketMachine class.
-
-* 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.
-Exercise 2.10 Do you notice any features of the constructor that make it significantly
-different from the other methods of the class?
-
-* Exercise 2.11 What do you think is the type of each of the following fields?
+### Exercise 2.1
+* 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?
+
+### 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?
+
+### Exercise 2.4

+
+### 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?
+
+### 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.
+
+### 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?
+
+* 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?
+
+### Exercise 2.8
+* Check whether or not it is possible to leave out the word `public` from the outer wrapper of the `TicketMachine` class.

+
+### Exercise 2.10
+* Do you notice any features of the constructor that make it significantly different from the other methods of the class?
+
+### Exercise 2.11
+* What do you think is the type of each of the following fields?
 ```
 private int count;
 private Student representative;
 private Server host;
 ```
-* Exercise 2.12 What are the names of the following fields?
+
+### Exercise 2.12
+* What are the names of the following fields?
 ```
 private boolean alive;
 private Person tutor;
 private Game game;
 ```
-* Exercise 2.13 In the following field declaration from the TicketMachine class
+### Exercise 2.13
+In the following field declaration from the TicketMachine class<br>
 ```
 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
-possible? Check by pressing the Compile button to see if there is an error message.
-Make sure that you reinstate 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. 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.
-* Exercise 2.16 To what class does the following constructor belong?
