Introduction to Programming

By: Nick Samoylov

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.

Overloading, overriding, and hiding

We have already mentioned method overriding and explained it in Chapter 2, Java Language Basics. Method overriding is replacing the methods implemented in a parent class (or default methods implemented in an interface) with the methods of the same signatures in the child class (or in the class that implements the interface, or in the child interface correspondingly). Method overloading is creating several methods with the same name and different parameters (thus, different signatures) in the same class or interface. In this section, we will discuss overriding and overloading the members of an interface, a class, and a class instance in more detail and will explain what hiding is as well. We start with an interface.
