[HD] EECS2030 F21 - Lab Solution Walk-Through - Lab4: Video Channel Platform

Walkthrough of the solution for lab number four focusing on programming with inheritance, highlighting the use of inheritance hierarchy, polymorphism, and dynamic binding.

Encouragement to compare and contrast solutions to learn more about inheritance, emphasizing the importance of attention to detail.

Instructions on setting up and importing the starter project in Eclipse for the lab.

Step-by-step guide on creating the Channeler class, including defining constructors and attributes.

Explanation of declaring constructors with parameters and initializing attributes in the Channeler class.

Instructions on running test cases to validate the Channeler class functionality and handling errors.

Demonstrating the override method for the Channeler class and ensuring correct output.

Implementation of the follow method in the Channel class to add followers to channels, including handling follower types like subscriber and monitor.

Covering scenarios for output handling based on follower and video counts, as well as dynamically accessing follower names.

The discussion starts with instantiating the programming pattern followed by defining constructors and inheritance between classes like follower, subscriber, and monitor.

Explanation of adding channels and followers, moving common constraints to the parent class, and implementing constructors and methods in subclasses.

The concept of bi-directional relations between channels and followers, implementing the follow method, and updating arrays with channel information.

Explanation of removing followers from arrays, shifting elements, and maintaining bi-directional relations between channels and subscribers.

Introduction to implementing the watch method in the subscriber class, handling errors with video names, and parameterizing the method for video recommendations.

Explanation of the programming solution with visual hints and instructions on how to program the solution.

Discussion on the process and progress of implementing the solution, addressing compilation errors, and identifying required statistics items.

Inclusion of statistics information such as number of views, maximum watch time, and average watch time for channels. Explanation of encoding statistical items.

Demonstration of visual representation of channel monitoring, arrays, and followers. Instructions on manipulating arrays and updating statistics.

Guidance on implementing the 'Watch' method, including looping over channels, updating statistics, and visualizing the execution process.

Explanation of a helper method for updating statistics, initializing attributes, and updating arrays based on channel index.

Guidance on finalizing the implementation, visualizing execution, and ensuring correctness in updating statistics based on channel interactions.
