Exception handling is a powerful mechanism for handling erroneous cases that occur while our code is running. It enables us to focus on the main execution of the program and separate the error-handling code from the expected execution path. The Java language forces programmers to write exception-handling code for library methods, and IDEs such as IntelliJ, Eclipse, and so on help us generate the boilerplate code necessary. However, without proper guidance and understanding, standard exception codes may result in more harm than good. This lesson is a practical introduction to exceptions that will push you to contemplate various aspects of exception handling, and will provide a number of rules of thumb that may be helpful when you are dealing with exceptions in your programming life.

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.
