Accessing Static variables

Question

public class Bicycle {

    private int cadence;
    private int gear;
    private int speed;
    private int id;
    private static int numberOfBicycles = 0;

    p         


        

Answer 1

 public int getID(){
    return numberOfBicycles;
}

public static int getNOB(){
    return numberOfBicycles;
}

In the Bicycle class

    Bicycle bc = new Bicycle(30, 90, 1);
    System.out.println(Bicycle.getNOB());
    System.out.println(bc.getID());

    Bicycle bc2 = new Bicycle(30,90, 1);
    System.out.println(Bicycle.getNOB());
    System.out.println(bc2.getID());

    Bicycle bc3 = new Bicycle(30,90, 1);
    System.out.println(Bicycle.getNOB());
    System.out.println(bc3.getID());

    Bicycle bc4 = new Bicycle(30,90, 1);
    System.out.println(Bicycle.getNOB());
    System.out.println(bc4.getID());

In the main class of BicycleTest worked just fine for me
