Maven and the IDE created the files for the sort program. They form the skeleton for our code, and now it is time to grow some muscles on them to let it move. We spent quite some time setting up the project by visiting the different build tools, only to learn how to compile the code.
I hope that this did not distract you much, but anyhow, we deserve to see some real code.
First, we will create the code for the sorting code, and after that, the code that invokes the sorting. The code that invokes the sorting is a kind of testing code. For simplicity, we will now simply use a public static void main() method to start the code. We will use the test framework in later chapters.
As for now, the code for the sorting will look like ...
