Overview of this book

Have you ever thought about making your computer do what you want it to do? Do you want to learn to program, but just don't know where to start? Instead of guiding you in the right direction, have other learning resources got you confused with over-explanations? Don't worry. Look no further. Introduction to Programming is here to help. Written by an industry expert who understands the challenges faced by those from a non-programming background, this book takes a gentle, hand-holding approach to introducing you to the world of programming. Beginning with an introduction to what programming is, you'll go on to learn about languages, their syntax, and development environments. With plenty of examples for you to code alongside reading, the book's practical approach will help you to grasp everything it has to offer. More importantly, you'll understand several aspects of application development. As a result, you'll have your very own application running by the end of the book. To help you comprehensively understand Java programming, there are exercises at the end of each chapter to keep things interesting and encourage you to add your own personal touch to the code and, ultimately, your application.

Classes and objects (instances)

A class is used as the template for creating objects. When an object is created, all fields and methods declared in the class are copied into an object. The combination of field values in an object is called object state. The methods provide object behavior. An object is also called an instance of a class.

Each object is created by using the operator new and a constructor that looks like a special kind of method. The primary duty of a constructor is to set an initial object state.

Let's us now have a closer look at Java classes and objects.

Java classes

Java classes are stored in .java files. Each .java file may contain several classes. They are compiled by the Java compiler javac and...
