Answer / rakesh
Java Abstract classes are used to declare common
characteristics of subclasses. An abstract class cannot be
instantiated. It can only be used as a superclass for other
classes that extend the abstract class. Abstract classes
are declared with the abstract keyword. Abstract classes
are used to provide a template or design for concrete
subclasses down the inheritance tree
