Best design pattern for the scenario

I have a scenario where I am using an interface implementation like

interface Sorter {
   public void sort(A a, B b){}
}

and then there are several implementation of the classes like

class RankSorter extends Sorter {
    public void sort(A a, B b) {
        // use a alone to sort 
    }
}
class WeightSorter extends Sorter {
    public void sort(A a, B b) {
        // use a alone to sort 
    }
}

and some more classes where we use only the value of a alone for the sort and finally one class like below where we use both a and b.

class MultiSorter extends Sorter {
    public void sort(A a, B b) {
         // use both a and b for the sort operation
    }
}

So my concern here is the value of b is passed to all of the sorters even though it's used only on one sorting class.

Is this the correct approach or is there a better approach ?
