can anyone tell me the reason why we have to use the Super() in first line of the constructor block while calling the super class constructor?Is there any special reason for that?Please explain me.

Yes, so that your superclass can get initialized properly, if there is any initialization that needs to be done. Assuming that your class depends on the superclass being in a specific state, the call to super will force that initialization to be performed.

You don't have to call super: the default super gets called automatically. The reason you might want to, however, is for times when you need a constructor other then the default constructor.
In the example below, the object kid_1 uses the default call, but the onject kid_2 uses an overloaded constructor.

And you definately need to call super(...) if the parent class has no "()" constructor.
