Computer Science and Databases made engaging and supportive

The student worked with the tutor on a C++ programming assignment involving the implementation of a hash table data structure. They focused on understanding the requirements, declaring and defining class members, and implementing core functions like `contains`, `match`, and `insert`, including the concept of rehashing. The next session is planned to define the `rehash` function and address any remaining implementation details.

The class focused on Java programming, specifically addressing issues with retrieving the current line number from a text area upon a mouse click. The student and tutor worked through debugging code, exploring potential methods to capture the correct line of text without requiring manual selection, and planned to continue this investigation in the next session.

The Student and Tutor reviewed the implementation of custom exceptions in Java, focusing on credit card and crypto payment scenarios. They then moved on to a JavaFX exercise involving updating a line number display within a text editor based on user interactions. The Student will continue working on this feature, applying guidance on event handling and data retrieval, with a follow-up planned for the next session.

The student and tutor explored the concept of semantics in distributed systems, with a primary focus on RPC call semantics. They discussed various types of call semantics, including "at least once" and "exactly once," and their implications for reliability and consistency. The session concluded with the student practicing identifying these semantics through example questions.

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.
