Summary

This chapter introduced you to the exciting world of Java programming. We started with explaining the main terms, and then explained how to install the necessary tools—the JDK and the IDE—and how to configure and use them.

With a development environment in place, we have provided readers with the basics of Java as a programming language. We have described Java primitive types, the String type, and their literals. We have also defined what an ID is and what a variable is and finished with a description of the main types of Java statements. All the points of the discussion were illustrated by specific code examples.

In the next chapter, we are going to talk about the object-oriented (OO) aspects of Java. We will introduce the main concepts, explain what a class is, what an interface is, and the relationship between them. The terms overloading, overriding, and hiding will also be defined and demonstrated in code examples, as well as usage of the final keyword.
