    Unhappy Add two times together

    Hey, i'm very new to Java and this is my first time using it . I'm just curious as to whether someone can help me out with a problem i have. I need the user to enter a start and end time for two different competitions, i then need to add the total time it took for each competition and display the results to the user. So far this is what i have:


    import javax.swing.JOptionPane;


    public class BiathlonSkiingEvent
    {

    public static void main(String[] args)
    {

    String numString1 = JOptionPane.showInputDialog("Enter your sprint start time (MM:SS:TT)");
    String numString2 = JOptionPane.showInputDialog("Enter your sprint end time (MM:SS:TT)");

    int firstNum = Integer.parseInt(numString1);
    int secondNum = Integer.parseInt(numString2);


    int sprintresult = firstNum + secondNum;


    String numString3 = JOptionPane.showInputDialog("Enter your biathlon start time (MM:SS:TT)");
    String numString4 = JOptionPane.showInputDialog("Enter your biathlon end time (MM:SS:TT)");

    int thirdNum = Integer.parseInt(numString3);
    int fourthNum = Integer.parseInt(numString4);


    int biathlonresult = thirdNum + fourthNum;

    JOptionPane.showMessageDialog(null, biathlonresult + sprintresult);

    System.exit(0);
    }

    I think you might want to use the StringTokenizer class as shown at
    Java Null error help.
    and
    StringTokenizer (Java Platform SE 6)

    Search the net for Joda time; it has a Duration class.

    db
    If you're forever cleaning cobwebs, it's time to get rid of the spiders.

    try to get the start time and finish time and subtract each other. That way you can get the duration. And compare and make the lowest one win. If you need more help post here.
