+- Yes, It just accumulates the amount of money inserted.
 	* What happens if you insert too much money into the machine – do you receive any refund?
+- No refund or error message
 	* What happens if you do not insert enough and then try to print a ticket?
+- It will still print 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.

 * Create another ticket machine for tickets of a different price.

 	* Does the printed ticket look different?
+- Looks the same, the total keeps accumulating.
 
 ### 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.

+No, does not let us know that is not possible.
 
 ### Exercise 2.8
 * Check whether or not it is possible to leave out the word `public` from the outer wrapper of the `TicketMachine` class.
+-Its defaults to public, you could leave it out.
 
 ### 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, getTicketNumber, getBalance, insertMoney, calculateTotal, incrementTicketNumber, printTicket
+- Fields: price, balance, total ticketNumber
+- Constructor: TicketMachine testTicketMachine = new TicketMachine.
 
 ### Exercise 2.10
 * Do you notice any features of the constructor that make it significantly different from the other methods of the class?
+- Its a test for the ticket machine to see if it runs properly.
 
 ### Exercise 2.11
 * What do you think is the type of each of the following fields?

 ### Exercise 2.14
 * Is it always necessary to have a semicolon at the end of a field declaration?
+- Yes, this will let you the statement is done.
 * Once again, experiment via the editor.
 * The rule you will learn here is an important one, so be sure to remember it.
