Encapsulation is one of the four key concepts in OOPS (Object Oriented Programming) namelyInheritance, Encapsulation,Abstractionand Polymorphism. Following definition helps you to understand the concept of encapsulation: Encapsulation is a process of hiding the data from the users or in other words we ...
For now, just remember that every Java application has a class definition, and the name of the class should match the filename in Java. public static void main(String[] args) { ... } This is the main method. Every application in Java must contain the main method. The Java compiler st...

Great approach to Java web technologies." -- Sue McFarland Metzger, Villanova University "I'm sure this [ATM] case study will be of immense value to practitioners and students of the object-oriented approach. Demystifies inheritance and polymorphism, and illustrates their use in getting ...
Before start, let's review the varieties of method calls in Java: Virtual call is designed for Java run-time polymorphism. Conceivably, the polymorphic virtual calls dispatching will become the most problematic and complex one for our analysis. ...
Excellent polymorphism chapter. Covers all the essentials of strings. Introduces JavaFX, the great new way to develop client applications in Java—I like the use of Scene Builder to create the GUI with drag-and-drop design rather than doing it by hand, which shows the way it should be done...
