What is the best way to get the ImplStructure variable and ImplStructureHandler in the Bayes class?

1) Should I pass both [ImplStructure and ImplStructureHandler] to the Bayes class in its constructor?

2) Should I create the another variable in ImplStructureHandler to store the value of b and then only pass ImplStructureHandler to the Bayes Class.

Or If there is any another way Please share?

My Code:

public class ImplStructure {

    private int a;
    private int b;


    public void build(int a, int b) {

        this.a = a;
        this.b = b;
    }


    public int getA() {
        return a;
    }


    public int getB() {
        return b;
    }
}


public class ImplStructureHandler{

    ImplStructure structure 

    public ImplStructureHandler(ImplStructure structure) {
        this.structure = structure;
    }


    public int compTotal(int c) {
        return c + structure.getA() + structure.getB();
    }
}


public class Bayes {

    public int doAddition(int d){

        //here need value of b from Structure and c from Structure Handler to do: d = b + c

        return d;

    }
}
