If statements go here to order stuff to order input from quickest time to slowest time

    private double time;
   
    public Runner(String r, double t)
    {
        runner = r;
        time = t;
    }
    public String getRunner()
    {
        return runner;
    }
    public double getTime()
    {
        return time;
    }
}


RunnerDemo.java

import java.util.Scanner;

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

        System.out.print("What is the name of the third runner? ");
        runner3 = keyboard.nextLine();

        System.out.print("What was the time for " + Runner1 + "? ");
        time1 = keyboard.nextDouble();
        System.out.print("What was the time for " + Runner2 + "? ");
        time2 = keyboard.nextDouble();
        System.out.print("What was the time for " + Runner3 + "? ");
        time3 = keyboard.nextDouble();

        Runner run1 = new Runner(runner1, time1);
        Runner run2 = new Runner(runner2, time2);
        Runner run3 = new Runner(runner3, time3);
       
        if (run1.getTime() > run2.getTime() && run1.getTime() > run3.getTime())
       {
              System.out.println(run1.getRunner());
              if (run2.getTime() > run3.getTime())
                   System.out.println(run2.getRunner());
              else
                   System.out.println(run3.getRunner());
        }
        if (run2.getTime() > run1.getTime() && run2.getTime() > run3.getTime())
       {
             System.out.println(run2.getRunner());
             if (run1.getTime() > run3.getTime())
                   System.out.println(run1.getRunner());
             else
                   System.out.println(run3.getRunner());
        }
        if (run3.getTime() > run1.getTime() && run3.getTime() > run2.getTime())
       {
            System.out.println(run3.getRunner());
            if (run1.getTime() > run2.getTime())
                   System.out.println(run1.getRunner());
            else
                   System.out.println(run2.getRunner());
       }
    }
}

This, or some variant, should work. I will note that there are a few easier ways using ArrayLists, but I don't know whether or not you have gotten that far into learning java yet, so I used the brute force method with the if statements. I hoped this helped! ^^

<Thoatt> I was very much into fluid dynamics
(SrMod: ~Rowan) but your opinion on that was... fluid?
<Thoatt> up to ferrofluid in magnetic field dynamics
(SrMod: ~Rowan) that sounds like an attractive field
(SrMod: ~Rowan) I'm going hard on the puns right now XD

Woohoo... everything is fine now...  I even finally realized I had > instead of < and had things ordered from slowest to fastest instead of the other way around.
