Fehlerbehandlung, often translated as error handling, is a fundamental concept in computer programming and system design. It refers to the mechanisms and strategies employed to detect, diagnose, and respond to errors or exceptional conditions that occur during the execution of a program or system. The primary goal of effective error handling is to maintain the stability and predictability of the software, preventing crashes, data corruption, and security vulnerabilities.

There are various approaches to error handling. One common method is the use of return codes, where functions signal their success or failure by returning specific values. Another widely adopted technique is exception handling, which allows programs to throw and catch exceptions – objects representing errors that disrupt the normal flow of execution. This approach separates error-handling code from the main program logic, leading to cleaner and more organized code.

Robust error handling involves not only detecting errors but also providing meaningful feedback to the user or system administrator, logging relevant information for debugging, and implementing graceful recovery strategies. This might include retrying an operation, using default values, or terminating the process in a controlled manner. The absence or inadequacy of error handling can lead to unpredictable behavior, making software difficult to maintain and unreliable in production environments. Well-designed error handling contributes significantly to the overall quality and trustworthiness of a software system.
