We all dream of a perfect world where there are no errors or unexpected situations, but in reality, this is impossible. Software development is also not free from errors and exceptions. Software developers don't want their software to break down, but unexpected exceptions happen every now and then. Consequently, handling these exceptions is necessary for developing awesome software. In this chapter, we familiarized ourselves with what an exception is in software development. We have also learned how to handle exceptions, why we need to handle exceptions, how to create custom exceptions, and many other important topics. When implementing exception handling in your application, try to follow best practices so that you get an application that runs smoothly.
