If you only want to know the name of the variable with the max value, that's easy, put (value, var name) into hashmap. After you get the max value among three, find the var name from hash map by using the max value as the key.

If you want to do different things based on which of three variables has the highest value, you can't do better than:

if (x > y && x > z) {
   // do stuff for when x is biggest
} else if (y > x && y > z) {
    // do stuff for when y is biggest
} else {
    // do stuff for when z is biggest
}

I deliberately didn't cover the case when two variables have the same value, both the highest, because you didn't say what you wanted to do. I'll leave that as an exercise for the reader.

If you have many more than three variables it gets more complicated, and you need a way of mapping a variable to an action.
