    Help with combining doubles and int

    Hello to all-
    I have a newbie problem. How do you combine a doubles with a int.

    First, the variables that I have are: dollars*years*rate/100

    Second, the "year" is in the int. format

    Third, the "dollars, rate and the divided by 100" are in the double format.

    I need to combine those to have just one value or total of all of those variables that I have listed in the second sentence.

    I have something like this, but this is not compilng:
    double paidInterest = (int)(dollars*years*rate/100);

    The paidInterest or total or one values, is the product that I need from the variable calculation.
    This paidInterest will display in GUI "show message box"

    Note, I have included below, a example of one out of the 3 "input messages" box. And of course the other 2 GUI,s are are in the double format.

    [
    int year;
    String oneRevolution = JOptionPane.showInputDialog(null,"How many years will you take the loan?(whole number)");
    year = Integer.parseInt(oneRevolution); ]


    Anyhelp or suggestions
    ThankYou

    Maybe because you're casting an int value to a double?

    Just guessing...
