This chapter explores the basics of Java programming. The tutorials 3.1 to 3.5 (included) are quite concise as they do not provide any complete code samples that you can run. Instead, those 5 tutorials introduce the basic concepts you need to know before being able to write your own code. Complete code samples will be provided in the tutorial 3.6 and the following.

Note that the code samples in this chapter make a very limited use of strings, although they are very easy to use in Java. The reason behind it is that you have not yet learned the object-oriented concepts of Java and because strings are objects, I believe it is wise to leave them to later chapters, for greater clarity.
