Overview: An object-oriented application is required for a virtual meeting system that manages participants and virtual meeting spaces. The application performs the following operations: 1. Load participant data from a data file 2. Create a new virtual room 3. Allocate participants to breakout rooms 4. Add a new participant to a breakout room 5. Display a list of all participants in a breakout room 6. Close a breakout room based on a room number 7. Open a breakout room based on a room number 8. Find a participant's breakout room number 9. Display a list of all breakout rooms managed by the system 10. Display a list of all breakout rooms managed by the system and the participants in each room The application consists of four domain classes: Virtual Meeting System, Virtual Room, BreakoutRoom and Participant. VirtualMeeting System Class The VirtualMeeting System class has the following methods. These are invoked by the Virtual Runner class.

A virtual room creates and manages up to a certain number of breakout rooms. Attribute Type Purpose name String The name of the virtual room breakoutRoomLimit int A constant that specifies the maximum number of breakout rooms allowed for a virtual room breakoutRooms BreakoutRoom[ ] A list of breakout rooms managed by the virtual room The VirtualRoom class has the methods below.

A breakout room hosts participants. It is created by a virtual room such that the breakout room's ID is based on the virtual room's name. Participants are added to the breakout room if it is open and if there is sufficient space to accommodate new participants. Duplicate participants (based on IDs) are not allowed. Attribute Type Purpose breakoutRoomID String breakoutRoomNumberCounter int breakoutRoomSize int Unique identifier for a breakout room in the virtual system formed by the combination of the virtual room name and a unique room number A class variable for producing unique integer values used in creating breakoutRoomID values A constant that specifies the maximum number (10) of participants allowed in a breakout room A list of participants who have been added to the breakout room Keeps track of the number of participants in the breakout room participants Participant[] numberOfParticipants int open boolean A flag for tracking whether the breakout room's state is open or closed The BreakoutRoom class has the methods below including accessors for the breakoutRoomID, numberOfParticipants and open variables. Method Signature Return Type Purpose BreakoutRoom (String name) Constructor addParticipant( String participantID) boolean findParticipant( String participantID) Participant Adds a new participant (no duplicates) with a valid ID to the (open) breakout room if the room is not filled and then returns true, otherwise returns false Locates and returns a participant based on a supplied (valid) ID if present in the (open) breakout room, otherwise returns null. Returns a list of the participants (ID) in the breakout room with the breakout room ID heading the list on a separate line Returns a String representation of the aggregated state of a BreakoutRoom Closes the breakout room, clears the participant list and resets any relevant state of the breakout room listParticipants() String toString() String closeBreakoutRoom(). void openBreakoutRoom() void Opens the breakout room and sets the state as open Additional notes: Example of toString() output for the first breakout room, associated with a virtual room called Seminar, hosting 4 participants and currently open: Seminar1 OPEN 4 Participant Class The Participant class models a participant in the virtual meeting system. Participants have the following state attribute. Attribute Type Purpose Predefined identifier for a participant in the virtual system. These must conform to an 8 digit format participantID String The Participant class has the methods below Method Signature Return Type Purpose Participant (String participantID) Constructor verifyID(String participantID) boolean Class method that validates that a non-null, participantID conforms to the required 8 digit format and returns true, otherwise false. getParticipantId() String Accessor for a participant's ID Returns a String representation of the state of a Participant formatted as follows: Participant: participantID toString().
