-\cf0 Exercise 2.11 What do you think is the type of each of the following fields?\
-private int count;   	INT\
-private Student representative; 	STRING\
-private Server host;	STRING\
-\
-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\
-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. \
-\
-	YES, the java lang read needs a semicolon to read statements\
-\
-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?\

-\
-Exercise 2.17 How many parameters does the following constructor have and\
-what are their types?\
-public Book(String title, double price)\
-\
-2 params, String & double\
-\
-Exercise 2.18 Can you guess what types some of the Book class\'92s fields might\
-be? Can you assume anything about the names of its fields?\
-\
-Exercise 2.19 Suppose that the class Pet has a field called name that is of type\
-String. Write an assignment statement in the body of the following constructor so\
-that the name field will be initialized with the value of the constructor\'92s parameter.\
-public Pet(String petsName)\
-\{\
-...\

-Exercise 2.20 Challenge exercise What is wrong with the following version of the\
-constructor of TicketMachine?\
-public TicketMachine(int ticketCost)\
-\{\
-int price = ticketCost;\
-balance = 0;\
-total = 0;\
-\}\
-TICKETCOST IS ALREADY ASSIGN AS AN INT.\
