Answer / harini
If the parent class method return type is object then child
class method return type need not be object. We can take
its child classes also.
The co-varient return types of no. class are
Byte/short/integer/long/float/double.
ex:
object-----string ----valid
number-----integer----valid
string------object----invalid
