    Access modifiers in java are used to control the access of other classes to access the class or method.

    There are different type of access modifiers used

    1.Public-It is the default access modifier it means that your class or method is visible to all other classes and method but in its package.

    2.Protected-It can be accessed by any class in its package and by subclass that extends it from another package./

    3.Private-It can be accessed in it own class only.

    public class Bicycle {
    
        private int cadence;
        private int gear;
        private int speed;
    
        // add an instance variable for the object ID
        private int id;
    
        // add a class variable for the
        // number of Bicycle objects instantiated
        private static int numberOfBicycles = 0;
            ...
    }
