Java Language Basics

Now that you have a general idea about Java and its related terms and tools, we will start discussing Java as a programming language.

This chapter will introduce the basic concepts of Java as an object-oriented programming (OOP) language. You will learn about classes, interfaces, and objects, and their relations. You will also learn the concepts and features of OOP.

In this chapter, we will cover the following topics:

The basic terms in Java programming
Classes and objects (instances)
Class (static) and object (instance) members
Interface, implementation, and inheritance
OOP concepts and features
Exercise – Interface versus abstract class

We call them basics because they are the founding principles of Java as a language, and there is more to learn before you can start programming professionally. For those who are learning Java for the first time,...

Key benefits

Enjoy your first step into the world of programming

Understand what a language is and use its features to build applications

Description

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.
