  1. Class Diagram v2

  2. ServerDOATS ServerIO ServerManager ServerSocket ClientHandler Socket StudentData Class Diagram - Server

  3. ServerDOATS • Constants - None • Class Variables - None • Instance Variables - None • Class Methods • void main(String argv[]) Creates and runs a ServerManager • Instance Methods - None

  4. ServerManager • Constants - None • Class Variables - None • Instance Variables • private HashMap<Integer,StudentData> uncheckedStudents • private int port • private StudentData instructor • Class Methods - None • Instance Methods • ServerManager() create uncheckedStudents, read configuration file, lntiliaze server.mainmenu() • void readConfigurationFile(String fileName) Opens filename and parses the file for configuration values • Map<Integer,StudentData> readStudentList(String filename) Opens filename and parses the file into StudentData objects (Map number => object) • void checkInStudents(HashMap<Integer, StudentData> numbers) Removes the listed numbers from uncheckedStudents • void execute() Then it creates ServerSocket, Creates and runs ClientHandler off of accepted connection

  5. ServerIO • Constants - None • Class Variables - None • Instance Variables - None • Class Methods • String getStudentFile(ServerManager server) Queries user for path to student list • void mainMenu(ServerManager server) Displays main server menu • booldisplayAbsent(HashMap<Integer, StudentData students>) Displays list of students and queries if it should be saved • void saveAbsent(HashMap<Integer, StudentData students>) Saves students back into file • Instance Methods • private ServerIO() This constructor should never be called

  6. ClientHandler • Constants - None • Class Variables - None • Instance Variables • ServerManager manager • Socket socket • BufferedReader input • DataOutputStream output • Class Methods - None • Instance Methods • ClientHandler(ServerManager m, Socket s) Saves m and s in manager and socket and Opens input and output on socket streams • void closeClientHandler() Closes all streams and socket • void execute() Sends instructor, Sends map of students from manager , Waits for response of array of student numbers, Once list is received, Closed connections, Checks in array of student numbers, and Displays list of absent students

  7. StudentData • Constants - None • Class Variables - None • Instance Variables • private int number • private String name • private String password • Class Methods - None • Instance Methods • StudentData(int Number, String Name, String Password) Saves values to appropriate variables • int getNumber() return this.number • String getName() return this.name • String getPassword() return this.password • bool checkPassword(String word) return password.equals(word)

  8. ClientDOATS ClientManager StudentData ClientIO NetworkManager Socket Class Diagram - Client

  9. ClientDOATS • Constants - None • Class Variables - None • Instance Variables - None • Class Methods • void main(String argv[]) Creates a ClientManager • Instance Methods - None

  10. ClientManager • Constants - None • Class Variables - None • Instance Variables • private StudentData instructor • private int hostPort • private String hostName • private HashMap<Integer,StudentData> studentList • private LinkedList<Integer> checkedIn • Class Methods - None • Instance Methods • ClientManager() Reads configuration and Calls ClientIO.mainMenu • void readConfigurationFile(String filename) Opens filename and parses the file for configuration values • void execute() Creates NetworkManager, then gets the instructor and student list (from NetworkManager), runs checkinMenu, adds result to checkedIn until instructor is returned, sends checkedIn, and cleans up

  11. NetworkManager • Constants - None • Class Variables - None • Instance Variables • Socket socket • BufferedReader input • DataOutputStream output • Class Methods - None • Instance Methods • NetworkManager(String hostName, in portNumber) Opens input & output on socket streams and Calls ClientIO.mainmenu() • void closeNetworkManager() Closes all streams and socket • StudentDatagetInstructor() Reads instructor from server and returns it • void sendStudents(LinkedList<Integer> students) Sends checked in students to server • HashMap<Integer, StudentData students> receiveStudents() Gets list of students from server

  12. ClientIO • Constants - None • Class Variables - None • Instance Variables - None • Class Methods • void mainMenu(ClientManager client) Display main menu, calling settingsMenu or client.run() as asked • void settingsMenu(ClientManager client) Prompt and set values in client as needed • int checkInMenu(ClientManager client) Prompt for student id to check in, and calls attemptCheckIn • boolean attemptCheckIn(StudentData student) Gives three tries for password entry and Return true for success and false for fail • Instance Methods • private ClientIO() This constructor should never be used
