Java provides a structured approach for dealing with errors that can occur while a program is running. This approach is referred to as “exception-handling.” The word “exception” is meant to be more general than “error.” Exception-handling is used to keep a program running even though an error is encountered that would normally stop the program. This lesson will explore file input and output (I/O) as an example of how exceptions are used.
The key topics for this lesson are:
- Exceptions
- Handling Exceptions
- Exception Messages
- Throwing Exceptions
- Reading From a File
- Writing to a File
