        drawRouteSegment(g, 0);          // Segment from 0 km to 1 km
        drawRouteSegment(g, 1);          // Segment from 1 km to 2 km

//I need to draw the route segments, and I'm having trouble adding a for loop.
Mainly because I'm not sure I understand how they work properly.

        for (int i = 0; i < spotHeights.length; i++) {
            What goes in the second line? spotHeight[i];
