AP Computer Science Principles taught interactively

Vasundhra and a learner reviewed Java interfaces and their implementation. The individual, who resides in Jacksonville, practiced implementing multiple interfaces in a single class. Vasundhra assigned an exercise to be completed independently, and they will review it in the next lesson, along with more complex questions on interfaces and abstract classes.

Vasundhra taught a student from Syracuse University about anonymous classes in Java, covering their creation from both regular classes and interfaces. The learner gained practical experience by overriding methods using anonymous classes with a 'Vehicle' class example. They also discussed a dedicated lesson for interface revision, and Vasundhra will send practice questions on logic building.

Vasundhra assisted Aaron in enhancing the UI of his drone service application using ZAML, focusing on rearranging and aligning UI elements within a grid layout. They adjusted stack panel orientations, modified grid column properties, and fine-tuned the height and width of list views to improve the application's visual appeal. Vasundhra offered to provide further assistance via text or email if Aaron encountered any issues.

Vasundhra and Darren collaborated on debugging a Java program that utilizes threads and timers. They encountered issues with NullPointerExceptions and integrating user input for thread creation, leading them to simplify the problem to focus on getting a basic timer operational. Vasundhra will independently develop a solution for the threading aspect and present it in their next lesson, also providing Darren with additional practice exercises on other Java topics.

Vasundhra assisted Aaron in debugging and enhancing a C# drone service application, focusing on implementing the 'remove' functionality for regular and express services and displaying a 'finished list' in the UI. They added a double-click event to remove items from the finished list and discussed cosmetic changes for the next session, scheduled for Monday.

Vasundhra guided an individual through improving a threaded matrix multiplication program in Java, focusing on performance optimization. The learner, a student from California State University, Sacramento, then began working on a new exercise involving single-dimensional array multiplication with user-defined thread counts and thread timeouts. Vasundhra offered to provide a solution for the array multiplication and timeout implementation for them to review.
