As you build any application, you can’t just assume that everything will run as expected. There are so many things that could cause your applications to not function properly or even crash. This course aims to teach developers how to handle such unforeseen scenarios in applications. Join instructor Cecili Reid as she teaches you the different types of exceptions, how to handle exceptions, and how to test an application to ensure it handles exceptions as expected. Cecili uses a sample Spring Boot web app as a case study and walks through practical scenarios where you’d want to use exception handling in that application. She starts with an initial application that doesn’t have exception handling mechanisms, and as she walks through each concept, she shows you how to improve the application by applying the concepts taught in each chapter. Cecili also shares some best practices to follow when handling exceptions in your applications.
