A>Default specifier in java is friendly,but there is no
keyword for it.When we simply write:
class{
........
}
JVM assumes it as having default specifier.Friendly
specifier tells the JVM that this class is accessible to all
the classes but in the same package.

B>Default constructor:it has the same name as that of the
class.It takes no arguments.It is the implicit constructor
and automatically generated in the absence of explicit
constructor.It calls the superclass constructor using super().

C>Default method:There is no default method in java.
