Computer Science and Databases made engaging and supportive

The tutor and student focused on Java programming concepts, specifically abstract classes, inheritance, and subclass instantiation. They worked through debugging errors related to creating objects from abstract classes and implemented functionalities for vehicle rentals, including rental history, discounts, and penalties. The next session will cover advanced JavaFX for creating nested windows and implementing a 'replace' feature in a text editor.

The session involved debugging and enhancing a Java Notepad simulator, specifically focusing on the 'Save' functionality. The Student implemented a suggested code modification to allow saving files with custom names. Then, the student began working on a new assignment related to object-oriented programming involving a vehicle rental system and completed the 'Vehicle' class.

The tutor and student reviewed the concept of simulations in AP Computer Science Principles, including its definition, benefits, and practical examples. They also practiced identifying and correcting bias in simulations and worked through problems involving filtering and sorting data in a spreadsheet context, with plans for further practice questions in the next session.

The tutor and student reviewed fundamental data structures like vectors and linked lists, along with C++ programming concepts such as move constructors and copy assignment operators. They also extensively practiced algorithmic complexity analysis using Big O, Big Theta, and Big Omega notations, including recursion and iterator implementation. The student will continue practicing these concepts for their upcoming test.

The Student and Tutor worked on developing the file open functionality for a text editor application using JavaFX. They implemented the `FileChooser` class to allow users to browse and select files, added file filtering for `.txt` documents, and included error handling for cancelled operations. The Tutor also provided initial code and guidance for the Student to integrate this into their project.

The Student and Tutor worked through practice problems on converting prefix expressions to postfix, analyzing time complexity, and understanding C++ concepts like constructors, destructors, and operator overloading. They also reviewed true/false questions covering data structures, algorithms, and complexity analysis, with plans to continue practice in a future session.
