Encapsulation is a programming concept that a language should support in order to separate an object's state from its behavior. This is typically facilitated by means of hiding an object's data representing its state from modification by external components.   Read More.....

You just cannot create an instance of the abstract class.  Read More.....

Objects and classes are a fundamental part of object-orientated programming, and therefore Java. A class contains both data (referred to as attributes), and executable code (referred to as methods). In the previous tutorial, we created a class that contained a single method ' main '. When the class was executed, the main method was called, and the application ran as a normal program.  Read More.....
