Factory Pattern (Nokia Mobile Example)

NokiaMobile.jave (Interface)

public interface NokiaMobile {

    public void price();

    public void label();

}

NokiaLumia.java ( Which will implement the interface)

public class NokiaLumia implements NokiaMobile {

   

    @Override

    public void price()

    {

        System.out.println("50,000");

    }

   

    @Override

    public void label()

    {

        System.out.println("Nokia Lumia L8");

    }

}

NokiaWindowPhone .java ( Which will implement the interface)

public class NokiaWindowPhone implements NokiaMobile{

   

    @Override

    public void price(){

        System.out.println("32,000");

    }

   

    @Override

    public void label(){

        System.out.println("Nokia Window Phone");

    }

   

}

NokiaMobileFactory.java

public class NokiaMobileFactory {

   

    public NokiaMobile getMobile(String mobile)

    {

        if(mobile==null)

        {

            return null;

        }

        else if(mobile.equalsIgnoreCase("Window Phone"))

        {

            return new NokiaWindowPhone();

        }

        else if(mobile.equalsIgnoreCase("Lumia Phone"))

        {

            return new NokiaLumia();

        }  

        return null;  }  }

Factory.java


public class Factory {

    public static void main(String[] args) {

       

        NokiaMobileFactory mobile = new NokiaMobileFactory();

       

        

        NokiaMobile lumia = mobile.getMobile("Lumia Phone");

        lumia.label();

        lumia.price();

       

        System.out.println("-----------------");

       

        NokiaMobile window = mobile.getMobile("Window Phone");

        window.label();

        window.price();

       

        System.out.println("-----------------");

      

    }

}
