Design, implement, and test classes that represent buildings, floors, and network access points for a company that monitors network access points in a building. Each building has a specified number of floors, each floor has a certain number of rooms, and each room contains a number of network access points. Each access point is labeled with its state (on or off) and, if it is on, the month it was turned on. The classes should include methods that allow users to query the number of floors, rooms, and access points, as well as the status of access points and the month they were turned on.

The classes must provide mutator methods for turning access points on or off and setting the month as needed. Use composition: a building contains floors, a floor contains rooms, and a room contains access points. The program should support adding additional floors, rooms, and access points, and manage exceptions gracefully by reporting errors if a non-existent floor, room, or access point is referenced.

Paper For Above instruction

Monitoring network access points within a building environment is essential for maintaining security, ensuring proper functionality, and facilitating management operations. To effectively manage this, a well-structured software system must be developed that employs object-oriented principles such as encapsulation, composition, and exception handling. The system should model buildings, floors, rooms, and network access points through dedicated classes, allowing flexible interaction and state management.

Design and Structure of the Classes

The system's core lies in its class hierarchy which embodies the geographical and functional relationships within the building. The primary classes include Building, Floor, Room, and AccessPoint; each responsible for specific attributes and operations. Employing composition, each Building object maintains a list of Floor objects, each Floor maintains a list of Room objects, and each Room contains a list of AccessPoint objects. This nested composition reflects physical structure, simplifying management and expansions.

Building Class

The Building class encapsulates properties such as a list of floors and methods to add or retrieve floors. It provides observer methods to determine the total number of floors, and access to individual floors through identifier or index, with robust exception handling if an invalid floor is referenced.

Floor Class

Similarly, the Floor class manages rooms within a specific floor. It offers methods to add rooms, count total rooms, and access specific rooms. Exception handling ensures errors are flagged when incorrect room identifiers are requested.

Room Class

The Room class contains a list of AccessPoint objects. It supplies methods to add access points, retrieve access points, and query the number of access points in the room. It also supports operations to find specific access points by label or identify their status.

AccessPoint Class

The core of network monitoring lies within the AccessPoint class, which records its current state (on/off) and the month it was turned on if applicable. Methods include turning on or off the access point, setting the month when turned on, and querying status details. Exception handling ensures operations are performed on valid access points only.

Operations and Functionalities

  • Adding new floors, rooms, and access points via respective mutator methods.
  • Turning access points on or off, with validation to prevent inconsistent states.
  • Setting the month of activation upon turning on an access point.
  • Querying the number of floors, rooms, and access points.
  • Checking the status of specific access points, including whether they are on or off, and the activation month.

Exception Handling and Error Reporting

The system employs custom exceptions, such as InvalidFloorException, InvalidRoomException, and InvalidAccessPointException, to handle cases where non-existent entities are targeted for operations. These exceptions ensure robustness by preventing invalid operations and informing users of errors precisely.

Implementation Strategy

The implementation begins with defining the classes, their attributes, constructors, and methods. Critical methods include mutators for changing states, setters for updating months, and accessors for data retrieval. Subsequent testing covers various scenarios, including adding entities, changing states, and exception cases, validating system integrity and responsiveness.

Conclusion

This object-oriented model provides a comprehensive solution for monitoring network access points within a building. Through clear class definitions, detailed methods, and robust error handling, it facilitates effective management, scalability, and accurate reporting, serving as a vital tool for building security and network administration teams.
