Java Exceptions
Java Exceptions are a mechanism for handling runtime errors and exceptional conditions in Java programs, allowing developers to separate error-handling code from regular program logic. They are objects that represent abnormal or unexpected events during program execution, such as file not found, division by zero, or network failures. The Java exception hierarchy includes checked exceptions (must be declared or handled), unchecked exceptions (runtime errors), and errors (serious system issues).
Developers should learn Java Exceptions to write robust, fault-tolerant applications that gracefully handle errors without crashing. This is essential for production code where reliability is critical, such as in enterprise systems, web servers, or financial software. Proper exception handling improves debugging, maintains program flow, and enhances user experience by providing meaningful error messages.
