Introduction to Programming

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.

How to execute the main(String[]) method

Before diving into the garbage collection process, we would like to review and summarize how to run an application from a command line. In Java, the following statements are used as synonyms:

  • Run/execute main class
  • Run/execute/start application
  • Run/execute/start main method
  • Run/execute/start/launch JVM or Java process

The reason for that is that each of the listed actions happens every time you execute one of them. There are also several ways to do it. We have already shown you how to run the main(String[]) method using IntelliJ IDEA and the java command line. Now, we will just repeat some of what has been said already and add other variations that might be helpful for you.
