abstract void moveTo(double deltaX, double deltaY); If a class includes abstract methods, then the class itself must be declared abstract, as in: public abstract class GraphicObject { // declare fields // declare nonabstract methods abstract void draw(); } When an abstract class is subcl...
Java Abstract Class Java Nested Class Java Enum Java Dynamic Proxy Interface Constants A Java interface can contain constants. In some cases it can make sense to define constants in an interface. Especially if those constants are to be used by the classes implementing the interface, e.g. in c...

Creates a common parent− As with the EventListener interface, which is extended by dozens of other interfaces in the Java API, you can use a tagging interface to create a common parent among a group of interfaces. For example, when an interface extends EventListener, the JVM knows that ...
Default methodsandabstract methodsin interfaces are inherited like instance methods. However, when the supertypes of a class or interface provide multiple default methods with the same signature, the Java compiler follows inheritance rules to resolve the name conflict. These rules are driven by the fo...

An abstract mosaic represents an abstract painting or a fractal: the only orientation constraint is that all the pieces have the same final orientation. To solve the mosaics, a Java application has been designed to run locally on a Diamond Touch and on the DigiTable platform. Because of the ...
