我在打印数字时遇到问题

Question

I am trying to do get user input with scanner for salesTotal variable and there is 2 if statements but it does not display my commision rate right.İt gives me 0 for every value that i write.

import java.util.Scanner;

public class Q2 {
    public static void main(String[] args) {

        double commisionRate = 0;
        double salesTotal;

        Scanner sc = new Scanner(System.in);

        salesTotal = sc.nextDouble();

    if(salesTotal <=10.000){
        commisionRate = (commisionRate*100)/2;
        System.out.println("the commision rate is : " +commisionRate);

    }
    else if(salesTotal>10.000){
        commisionRate = (commisionRate*100)/5;
        System.out.println("the commision rate is : " +commisionRate);
    }


}
}

Answer 1

commisionRate is a variable that depends from the user input salesTotal , you are reading the salesTotal but never using it to calculate the commisionRate

you should be doing instead:

 if(salesTotal <=10.000){
        commisionRate = (salesTotal *100)/2;
        System.out.println("the commision rate is : " +commisionRate);

    }
    else if(salesTotal>10.000){
        commisionRate = (salesTotal *100)/5;
        System.out.println("the commision rate is : " +commisionRate);
    }
