By: SkillSprints Inc., Mark Lassoff

Overview of this book

Java is an object-oriented programming language, and is one of the most widely accepted languages because of its design and programming features, particularly in its promise that you can write a program once and run it anywhere. Java Programming for Beginners is an excellent introduction to the world of Java programming, taking you through the basics of Java syntax and the complexities of object-oriented programming. You'll gain a full understanding of Java SE programming and will be able to write Java programs with graphical user interfaces that run on PC, Mac, or Linux machines. This book is full of informative and entertaining content, challenging exercises, and dozens of code examples you can run and learn from. By reading this book, you’ll move from understanding the data types in Java, through loops and conditionals, and on to functions, classes, and file handling.

Sometimes, it might even be a hardware failure; a lot of errors can't really be attributed to any one single source, but they are going to happen. The way that our program handles the error case is often just as, if not more, important as how it handles ideal use cases.

In this section, we're going to take a look at Java exceptions. Using Java exceptions, we can detect and catch, and in some cases recover from, errors that occur within our program. As we go through exceptions, there's something really important to keep in mind. Exceptions are called exceptions because they exist to handle exceptional cases, things that we either couldn't handle or couldn&apos...
