Java arithmetics for calculating a percentage

Question

I have a little problem in my java application.

I have to calculate the score they have when they finish, I use this method:

public Float ScoreProcent(in         


        

Answer 1

Float num = (float) (100 / y * x);

The problem is that you weren't using the float you just built before.

Alternatively I suggest this :

public float getScorePercent(int questions, int correct){
    return 100f * correct / questions;
}

It's generally advised to avoid Float and use float, except when you really need objects (that is rarely).
