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.

Exercise – Design patterns

There are many OOD patterns that have shared software-design solutions of specific coding problems. OOD patterns are also often used by programmers as the way to talk about different implementations.

They are traditionally grouped into four categories: creational, behavioral, structural, and concurrency patterns. Read about them and:

  • Name one pattern in each category
  • Name three patterns we have used already

Answer

The four patterns—one from each of the four categories—could be the following:

  • Creational patterns: Factory method
  • Structural patterns: Composite
  • Behavioral patterns: Visitor
  • Concurrency patterns: Messaging pattern

In this book, we have already used the following...
