oop - Overriding a method with more parameters in java? -

-

i have base class method called execute :

class {     public execute(int a){} }

i have class b, extends a, execute method needs more parameters:

currently, solution using optional parameters :

class b extends {     public execute(int a, object... parameters){         long b = (long)parameters[0];         boolean c = (boolean)parameters[1];         ....     } }

this still ugly because must cast on parameters. there other options situation?

you can add execute(int a, int b) in b, won't override execute(int a) method, overload it. both method callable on instance of b.
