False
Explanation:
An abstract class is a class declared abstract - it may or may not include abstract techniques. It is not possible to instantiate abstract classes, but they can be sub-classed.
Abstract method declaration
abstract void moveTo (double X, double Y);
Usually the subclass offers solutions for all of the abstract techniques in its parent class when an abstract class is sub-classed. If not, however, the subclass must be declared abstract as well.
Example
public abstract class GraphicObject {
/ / declaring fields
/ / declaring non-abstract methods
abstract void draw ();
}
