Discover what is encapsulation in Java, the technique of hiding class data and behavior behind public methods. Improves code quality, security, and maintenance.
An interface is a special form of an abstract class which does not implement any methods. In Java, you create an interface like this: interface Interface { void interfaceMethod(); } Since the interface can't implement any methods, it's implied that the entire thing, including all the met...
A class is the blueprint from which individual objects are created. The following Bicycle class is one possible implementation of a bicycle: class Bicycle { int cadence = 0; int speed = 0; int gear = 1; void changeCadence(int newValue) { cadence = newValue; } void changeGear(int new...
classes. For instance, if we have an abstract base class called "Canine", any deriving classshouldbe an animal that belongs to the Canine family (like a Dog or a Wolf). The reason we use the word "should" is because it is up to the Java developer to ensure that relationship is ...
