Error and Exception Handling is a crucial aspect of software development that focuses on detecting, managing, and responding to runtime errors and unexpected conditions in a program. Effective handling of errors and exceptions ensures that applications remain stable, provide useful feedback to users, and maintain data integrity even in the presence of issues.

• Stability: Proper handling of errors and exceptions helps prevent crashes and ensures that the application continues to operate, even when unexpected problems occur. This improves the overall stability and reliability of the software.
• User Experience: Graceful handling of errors enhances user experience by providing meaningful error messages and guiding users on how to correct issues. This helps prevent frustration and confusion when things go wrong.

• Error Handling: Deals with errors that occur during program execution. These are often systematic issues that can be anticipated, such as file not found or network connection failures. Error handling typically involves checking for specific error conditions and responding appropriately.
• Exception Handling: Focuses on handling unexpected events that disrupt the normal flow of execution. Exceptions are typically raised when an error occurs, and exception handling involves catching these exceptions and executing code to handle them or recover from them.

• Try-Catch Blocks: Use try-catch blocks to enclose code that might throw exceptions. This allows you to catch exceptions and handle them without disrupting the normal execution flow.
• Logging: Implement logging to record errors and exceptions, which helps with debugging and understanding the circumstances that led to the issue. Logs should include detailed information to facilitate troubleshooting.
• User Feedback: Provide clear and actionable feedback to users when an error occurs. Avoid exposing technical details that might confuse users, and instead offer guidance on how to resolve or report the issue.

Snippet from Wikipedia: Exception handling

In computing and computer programming, exception handling is the process of responding to the occurrence of exceptions – anomalous or exceptional conditions requiring special processing – during the execution of a program. In general, an exception breaks the normal flow of execution and executes a pre-registered exception handler; the details of how this is done depend on whether it is a hardware or software exception and how the software exception is implemented.

Exceptions are defined by different layers of a computer system, and the typical layers are CPU-defined interrupts, operating system (OS)-defined signals, programming language-defined exceptions. Each layer requires different ways of exception handling although they may be interrelated, e.g. a CPU interrupt could be turned into an OS signal. Some exceptions, especially hardware ones, may be handled so gracefully that execution can resume where it was interrupted.
