The State Patrol Ticket-Processing System (Revisited) In Chapter 3, you identified use cases and considered the domain classes for the State Patrol Ticket Processing System. Review the descriptions in Chapter 3 for the use case Record a traffic ticket. Recall that the domain classes included Driver, Officer, Ticket, and Court. 1. Draw a domain class diagram for the ticket-processing system based on the four classes just listed and include attributes, association, and multiplicity.
2. List the classes that would be involved in the use cases and decide which class should be responsible for collaborating with the other classes for the use case Record a traffic ticket. Consider some possibilities: 1) a driver object should be responsible for recording his/her ticket; 2) the officer object should be responsible for recording the ticket that he or she writes; and 3) a ticket object should be responsible for recording itself.
3. Create a set of CRC cards showing these classes, responsibilities, and collaborations for the use case.
4. Draw a first-cut design class diagram (DCD) based on your CRC cards.

File account. java (see previous exercise) contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a string representation. note that the constructor for this class creates a random account number. save this class to your directory and study it to see how it works. then write the following additional code: 1. suppose the bank wants to keep track of how many accounts exist. a. declare a private static integer variable numaccounts to hold this value. like all instance and static variables, it will be initialized (to 0, since it’s an int) automatically. b. add code to the constructor to increment this variable every time an account is created. c. add a static method getnumaccounts that returns the total number of accounts. think about why this method should be static - its information is not related to any particular account. d. file testaccounts1.java contains a simple program that creates the specified number of bank accounts then uses the getnumaccounts method to find how many accounts were created. save it to your directory, then use it to test your modified account class.
