The operator > is undefined for the argument type(s) java.util.Random, java.util.Random

I am trying to create a horse race betting game. I'm having trouble comparing the values of the horses to each other to see which one wins.

In the if statement I try to compare the value of horse1 with the value of horse2 and horse3. But I get the error of: he operator > is undefined for the argument type(s) java.util.Random, java.util.Random

//create loop to repeat races when one finishes (keep balance)
    nextRace = true;
    while (nextRace == true)
    {
        bal = 200;
