data validation

Question

I am writing a loan calculate with data validation. My maximum loan amount is 1,000,000 and I am using the method below to validate. When I enter 1,000,000 into the program it comes back with my error method. I thought (d >= max) would allow me to go up to and including my max. Can anyone see a problem with this method or is it possible I should be looking elsewhere in my code for a problem.

Any help is appreciated.

public static double getDoubleWithinRange(Scanner sc, String prompt, double min, double max)
{
    double d = 0.0;
    boolean isValid = false;
    while (isValid == false)
    {

        d = getDouble (sc, prompt);
        if (d <= min)
        {
            System.out.println(
                    "Error! Number must be greater than " + min + "." );
        }
        else if (d >= max)
        {
            System.out.println("Error! Number must be less than " + max + "." );
        }

        else
            isValid = true;
    }
    return d;

//Get input from user System.out.println("DATA ENTRY"); double loanAmount = getDoubleWithinRange (sc, "Enter loan amount: ",0, 1000000); double interestRate = getDoubleWithinRange (sc, "Enter yearly interest rate: " , 0, 20); int years = getIntWithinRange (sc, "Enter number of years: ",0,100);

Answer 1

Use else if (d>max), since you want up to 1,000,000 (and 1,000,000 can be included).

Answer 2

you are saying if the amount is greater than or equal to one million cause an error. you want to say if it is greater than show an error
