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.

What are the Java language elements?

As with any programming language, Java has a grammar that is applied to the language elements. The elements are building blocks used to compose language structures that allow the programmer to express intent. Elements themselves have different levels of complexity. Lower-level (simpler) elements enable building higher-level (more complex) ones. For a more detailed and systematic treatment of Java grammar and language elements, please see the Java Specification (https://docs.oracle.com/javase/specs).

In this book, we start with input elements that belong to one of the lowest levels. They are called input elements because they serve as input to the Java compiler.
