12. Exception Handling
Exception handling is a fundamental aspect of programming that enables developers to manage runtime errors gracefully. The chapter focuses on Java-style exception handling, covering essential keywords and syntax as well as best practices to improve code robustness and maintainability. By differentiating between checked and unchecked exceptions and discussing exception propagation, it guides programmers on how to avoid common pitfalls associated with error management.
Sections
This section introduces the concept of exception handling in programming, emphasizing its role in dealing with errors gracefully.
Errors in programming can be classified into compile-time, runtime, and logical errors.
Understanding the hierarchy of exceptions helps manage error handling effectively.
Using try, catch, and finally blocks is essential for trapping exceptions and executing cleanup code.
Exception
An event that disrupts the normal flow of program execution.
Error
A serious issue that usually cannot be handled in the code.
Checked Exception
Exceptions that must be caught or declared during compile time.
Unchecked Exception
Exceptions that the programmer is responsible for managing at runtime.
finally block
A code block that always executes after try or catch blocks, used for cleanup.
