Summary

In this chapter, we have developed a very basic sort algorithm. It was made purposefully simple so that we could reiterate the basic and most important Java language elements, classes, packages, variables, methods, and so on. We also looked at build tools, so we are not empty handed in the next chapters when projects will contain more than just two files. We will use Maven and Gradle in the following chapters.

In the very next chapter, we will make the sort program more complex, implementing more effective algorithms and also making our code flexible, giving us the opportunity to learn more advanced Java language features.
