Grade 11 Notes
Errors (exceptions) are handled using try-catch. Most of the examples relate to input/output since most I/O operations throw exceptions and require an understanding of try-catch. Thus these two topics are tightly integrated. The minor topics of constants and enums are not connected to errors or file I/O in any way.
