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.

OOP concepts

Now, we can talk about concepts that will make more sense to you, compared to presenting them before you learned the main terminology and saw the code examples. These concepts are:

  • Object/class: This keeps the state and behavior together
  • Encapsulation: It hides the state and details of the implementation
  • Inheritance: It propagates behavior/signatures down the chain of class/interface extensions
  • Interface: It isolates signatures from their implementations
  • Polymorphism: This allows an object to be represented by multiple implemented interfaces and any of the base classes, including java.lang.Object.

By now, you are familiar with all of the above, so this is going to be mostly a summary, adding only a few details. That's how we learn – from observing specific facts, building a bigger picture, and improving that picture as new observations come in. We do...
