A13 Introduction page 1 of 12

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:

  1. Exceptions
  2. Handling Exceptions
  3. Exception Messages
  4. Throwing Exceptions
  5. Reading From a File
  6. Writing to a File
