Print object name

Question

Hi all,
I am new to Java learning, I would like to print the object name in below program.
Output should look like
bike1 Cadence :40 speed :12 Gear :1
bike2 Cadence :50 speed :60 Gear :2
What are the changes I need to do to get the desired output.

class Bicycle {
    int cadence = 0;
    int speed   = 0;
    int gear    = 1;
    void changeCadence(int newValue)
        cadence = newValue;
    void changeGear(int newValue)
        gear =newValue;
     void increaseSpeed(int increment)
        speed = speed + increment;
      void decreaseSpeed(int decrement)
        speed = speed - decrement;
      void printStatus()
          System.out.println("Cadence :" + cadence + " speed :" + speed
                  + " Gear :" + gear);
class BicycleDemo {
     public static void main(String[] args)
         //create two bicylce objects
         Bicycle bike1 = new Bicycle();
         Bicycle bike2 = new Bicycle();
         bike1.changeCadence(40);
         bike1.changeGear(1);
         bike1.increaseSpeed(12);
         bike1.printStatus();     
         bike2.changeCadence(50);
         bike2.changeGear(2);
         bike2.increaseSpeed(60);
         bike2.printStatus();
}Thanks

Hi Raghu,
Here you already have the object, so you have the object name as well. All you need is to print the name. So you can pass the name of object as parameter to printStatus() method and you are done. Code changes are below:
void printStatus(String name)// here String parameter is added
          System.out.println(name + " Cadence :" + cadence + " speed :" + speed
                  + " Gear :" + gear);
      }And inside the main method call the printStatus() method with object name.
bike2.printStatus("bike1 ");      // calling with the name of object
bike2.printStatus("bike2 ");Amit
