A try-catch structure, often referred to as a try-catch block or exception handling mechanism, is a fundamental programming construct used to manage potential errors or exceptional events that can occur during the execution of a program. This mechanism allows developers to anticipate situations where code might fail, such as attempting to access a file that doesn't exist, dividing by zero, or encountering network connectivity issues.

The try block encloses the code that might potentially throw an exception. If an exception occurs within the try block, the program's execution immediately jumps to the corresponding catch block. The catch block is designed to handle specific types of exceptions. It contains the code that will execute if a matching exception is detected, allowing the program to gracefully recover, log the error, inform the user, or take other predefined actions instead of crashing.

If no exception occurs within the try block, the catch block is skipped entirely. Many programming languages also support an optional finally block, which executes regardless of whether an exception was thrown or caught. This is useful for performing cleanup operations, such as closing files or releasing resources, ensuring they are always handled. The primary purpose of try-catch constructs is to improve the robustness and reliability of software by providing a structured way to deal with unexpected situations.
