    Hey! If you want to use the switch or if/else if statements, I'd recommend reading The if-then and if-then-else Statements (The Java™ Tutorials > Learning the Java Language > Language Basics) and The switch Statement (The Java™ Tutorials > Learning the Java Language > Language Basics). If you have any other questions, please don't hesitate to ask.

    this is what i have so far but i dont think its correct.

    import java.util.Scanner;

    import javax.swing.JOptionPane;
    public class InsuranceQuotes {

    private static String status;

    /**
    * @param args
    */
    public static void main(String[] args) {
    // TODO Auto-generated method stub
    Scanner keyboard = new Scanner (System.in);

    System.out.print("Are you male or female? Answer m or f:");
    char appGender = keyboard.next().charAt(0);
    short insurance = 4000;
    double discount = 0.5 ;

    if( appGender=='f')
    {
    discount = 5 / 100*insurance;
    }
    else if( appGender=='m')
    {
    discount = 0;
    }
    double inTotal = (discount - insurance);
    System.out.println ("your total is " + inTotal);

    I think you should try using println statements to see what's wrong. Try printing out your variables (i.e. discount, insurance). Try and see what happens to discount and insurance when you enter 'f', then see what happens you enter 'm'. Also, consider this:

    int/int = int
    double/int = double
    int/double = double
    double/double = double

    Also, short ranges from -32,768 to 32,767. Just something to think about when you do your calculations
