 ### Exercise 2.2
 * What value is returned if you check the machine’s balance after it has printed a ticket?
-
+- The value is 0.
 ### 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? 
+	- The refund and balance stays at 0 even with different prices.
 	* What happens if you insert too much money into the machine – do you receive any refund?
+	- There is no refund.
 	* What happens if you do not insert enough and then try to print a ticket?
+	 - The ticket still prints regardless of the price.
 
 ### 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.

 * Create another ticket machine for tickets of a different price.
 	* Buy a ticket from that machine.
 	* Does the printed ticket look different?
-
+      - There is no difference.
 ### 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, it must be written properly.
 * 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?
+	 - Yes, there are red marks on the 'TicketMachine' class.
 	* What error message do you get when you now press the compile button?
+	 - It states error found in class.
 	* Do you think this message clearly explains what is wrong?
-
+	 - Yes, it marks the line of code that needs to be fixed in red in order to be complied.

 ### Exercise 2.8
 * Check whether or not it is possible to leave out the word `public` from the outer wrapper of the `TicketMachine` class.
-
+- Yes, there are no errors.
 ### 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- printTicket, insertMoney, getTicketNumber, getPrice
+     Fields- ticketNumber, total, balance, price
+     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 features of the constructor is different because it is the same 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

 ### 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

 	* 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?
+-  It is always necessary to have a semicolon.
 * Once again, experiment via the editor.
 * The rule you will learn here is an important one, so be sure to remember it.
