Superclass vs Subclass part 2

MountainBike.java

public class MountainBike extends Bicycle {
        
    // Now, the Bicycle class is the SUPERCLASS and the MountainBike class is the SUBCLASS
    // the MountainBike subclass adds one field
    public int seatHeight;
    // the MountainBike subclass has one constructor
    public MountainBike(int startHeight,
                        int startCadence,
                        int startSpeed,
                        int startGear) {
        super(startCadence, startSpeed, startGear);
        seatHeight = startHeight;
    }   
        
    // the MountainBike subclass adds one method
    public void setHeight(int newValue) {
        seatHeight = newValue;
    }   
}
