java - Methods for an interface with a variable number of parameters -

i'd ask if it's possible in java have declaration of method in interface but, want methods defined have variable number of input parameters (for example, of same type). thinking in this:

public interface equalscriteria {      public boolean isequal(string... paramstocheck);      // not equals(object obj) !!!  } 

and 1 class implements equal criteria like, example:

public class commonequals implements equalscriteria {     private string name;     private string surname;      ....     @override     public boolean isequal(string othername, string othersurname) {         return name.equals(othername) && surname.equals(othersurname);     }  } 

but maybe, want other criteria in part of code, this

public class specialequals implements equalscriteria {     ....     @override     public boolean isequal(string othername, string othersurname, string passport) {         return name.equals(othername) && surname.equals(othersurname) && passport.equals(passport);     }  } 

ps: problem little bit more complicated, useful me.

a better way be:

public interface equalscriteria {     public boolean isequal(equalscriteria other);      public string[] getparam();     // not equals(object obj) !!! } 

and then:

public class commonequals implements equalscriteria {     private string name;     private string surname;       @override     public boolean isequal(equalscriteria other) {      if(other==null) return false;      return arrays.aslist(getparam()).equals(arrays.aslist(other.getparam()));     }      } 

this way, if number of strings changes, still work.
