 * '''An instance init block runs right after the call to super() in a constructor''' (ie. after all the super-constructors have run).
 * In case of multiple init blocks (either instance and static) they run in the order in which they are defined.
 * Exceptions in init blocks can be handled using try-catch mechanism.
