Introduction to Object-Oriented Programming with Java III

Exceptions, Data Structures, Recursion, and GUIs

Olufisayo Omojokun

This course provides students with the knowledge to handle and even create exceptions to achieve graceful error handling in programs. They will also create and utilize data structures, including lists and files. Students will also learn about recursion and how it can be a useful approach to repetition in a program. Finally, students will learn how to develop basic graphical user interfaces (GUIs) using JavaFX.
