The student and tutor worked on implementing custom exceptions in Java and managing them with try-catch blocks. The discussion covered the syntax for throwing exceptions and the correct placement and structure of try-catch blocks to ensure robust error handling. The student plans to complete similar exception handling for other parts of their code.

The tutor guided the student in developing two core functions for a programming library project: a dice rolling simulator and a string manipulation function that capitalizes vowels and lowercases consonants. They worked on refining the dice rolling logic and integrating the new string function, ensuring all project requirements for the library were met.

The student and tutor reviewed synchronization problems, including the Readers-Writers problem, the Dining Philosophers problem illustrating deadlock, and barrier synchronization. They discussed the challenges and solutions for concurrent access to shared resources and planned for the student to practice with practical questions.

The student and tutor focused on distributed systems, beginning with an overview of inter-computer communication challenges and layered network architectures. They then delved into network sockets as an OS interface for communication, followed by an introduction to Remote Procedure Calls (RPC) as a higher-level abstraction to simplify network programming and address socket limitations. The next session will involve reviewing questions prepared by the tutor on these topics and potentially other related lecture slides.

The Student and Tutor worked on debugging a Java application, focusing on resolving issues related to variable scope, object accessibility in event handlers, and the functionality of a text replacement feature. They used debugging techniques such as moving variable declarations, analyzing method return types, and implementing print statements to trace data flow and identify the root cause of the replacement not working, which appeared to be related to a blank string being returned from a key method.

The tutor and student worked on debugging a Rock, Paper, Scissors game application. They focused on implementing random computer choices, correctly determining the winner based on game rules, and updating scores. The session involved code analysis, modification of functions, and the introduction of conditional logic for game outcome determination.
