Finally, a complete Java program is covered for you to try. Chapter four gets more in-depth. Types are the subject, and the depth is great. Some C-isms are covered, ie. More compex types are also covered.
Operators are next on the agenda, in chapter five.
This includes binary operators, arithmetic operators, boolean operators, and so on. Note that in Java there is an enforced distinction between these types, unlike in C. Chapter six is a little longer. Flow control is covered, ie. Chapter seven starts to get beyond the rudiments, and into the raison-d'etre of Java, classes. For programming in the large, Java has several features.
