Try-Catch-Finally

The “try-catch-finally” construct is a fundamental feature in many programming languages, designed to handle exceptions and manage errors gracefully. The “try” block contains code that may potentially throw an exception, while the “catch” block is used to handle any exceptions that arise, allowing developers to respond to errors without crashing the program. The “finally” block, which is optional, ensures that specific cleanup code is executed regardless of whether an exception occurred, making it ideal for resource management. This structure enhances code reliability and maintainability by providing a clear mechanism for error handling and cleanup operations.
