Class Bicycle

This is an example of a class taken from the Java Tutorial:

class Bicycle {

       int cadence = 0;
       int speed = 0;
       int gear = 1;

       void changeCadence(int newValue) {
            cadence = newValue;
       }

       void changeGear(int newValue) {
            gear = newValue;
       }

       void speedUp(int increment) {
            speed = speed + increment;   
       }

       void applyBrakes(int decrement) {
            speed = speed - decrement;
       }

       void printStates() {
            System.out.println("cadence:"+cadence+" speed:"+speed+" gear:"+gear);
       }
}
