Help with Symbol Error

I am following the Oracle tutorials for learning Java and I tried to compile the example code but it returned the "cannot find symbol error". Please Help!

Code:

---

class BicycleDemo {
    public static void main(String[] args) {
 
        // Create two different
        // Bicycle objects
        Bicycle bike1 = new Bicycle();
        Bicycle bike2 = new Bicycle();
 
        // Invoke methods on
        // those objects
        bike1.changeCadence(50);
        bike1.speedUp(10);
        bike1.changeGear(2);
        bike1.printStates();
 
        bike2.changeCadence(50);
        bike2.speedUp(10);
        bike2.changeGear(2);
        bike2.changeCadence(40);
        bike2.speedUp(10);
        bike2.changeGear(3);
        bike2.printStates();
    }
}

---

Code:

---

BicycleDemo.java:6: error: cannot find symbol
Bicycle bike 1 = new Bicycle();
^
symbol: class Bicycle
location: class BicycleDemo
BicycleDemo.java:6: error: cannot find symbol
Bicycle bike 1 = new Bicycle();
                            ^
symbol: class Bicycle
location: class BicycleDemo
BicycleDemo.java:7: error: cannot find symbol
Bicycle bike 2 = new Bicycle();

BicycleDemo.java:7: error: cannot find symbol
Bicycle bike 2 = new Bicycle();
                            ^

location: class BicycleDemo
4 errors

The error is very explicit: the compiler cannot find a class named Bicycle.

Have you created a Bicycle class or are you skipping ahead in the tutorial without going through the earlier steps?

db

is this the code for the class? and where does it need to be?

Code:

---

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);
    }
}

Never mind, your input has allowed me to fix it myself, thank you.

It's all there in the tutorials. Why should anyone have to repeat the same things here?
