In this lesson, we covered exceptions in Java from a practical point of view. First, we discussed the motivation behind exception handling and how it provides advantages over other ways of trying to handle erroneous cases. Then, we took the point of view of a newbie Java programmer with a powerful IDE and provided guidance on how to best handle and specify exceptions. Later, we dived deeper into causes of exceptions and various exception types, followed by the mechanics of exception handling using the try/catch, try/catch/finally, and try with resource blocks. We finish this discussion with a list of best practices to guide your decision process in various situations that involve exceptions.

Overview of this book
Since its inception, Java has stormed the programming world. Its features and functionalities provide developers with the tools needed to write robust cross-platform applications. Java Fundamentals introduces you to these tools and functionalities that will enable you to create Java programs.
The book begins with an introduction to the language, its philosophy, and evolution over time, until the latest release. You'll learn how the javac/java tools work and what Java packages are - the way a Java program is usually organized. Once you are comfortable with this, you'll be introduced to advanced concepts of the language, such as control flow keywords. You'll explore object-oriented programming and the part it plays in making Java what it is. In the concluding chapters, you'll get to grips with classes, typecasting, and interfaces, and understand the use of data structures, arrays, strings, handling exceptions, and creating generics.
By the end of this book, you will have learned to write programs, automate tasks, and follow advanced courses on algorithms and data structures or explore more advanced Java courses.
