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.

Reactive Systems

In the final chapter of this book, we'll break the flow of the connected narrative and jump closer to real-life professional programming. As more data gets processed and services become more sophisticated, the need for more adaptive, highly scalable, and distributed applications grows exponentially. That is what we are going to address in this chapter—how such a software system may look in practice.

In this chapter, we will cover the following topics:

  • How to process a lot of data quickly
  • Microservices
  • Reactive systems
  • Exercise Creating io.reactivex.Observable
