abstract class is a class which may or may not contain
abstract method.
abstract class can,t be instantiated i.e. we can,t
create object of an abstract class.
abstract class can be subclasses .
abstract class is a class which is declared abstract.
if any class contain abstract method then it can be
declared abstract.
example
abstract class{

abstract public void display();//abstract method
}
abstract method is method which is declared but not
implemented i.e. without braces followed by semicolon.
