You are asked to write a Java program to calculate the commercial value of the stamps owned by a philatelist. Each philatelist has a name and a collection of stamps. The stamps can be divided into two groups: Group I and Group II. Each stamp has the following attributes: name, face value, and publication year. The commercial value of a stamp is calculated as follows:1. for a stamp in Group I, the commercial value is twice its face value,2. for a stamp in Group II, the commercial value is triple its face value.You need to follow the following interfaces:public interface IStamp { double get_faceValue();String get_name(); // return the name of a stamp Int get_publicationYear(); //return the Publication year of a stamp}public interface IPhilatelist { ArrayList get_allStamps(); void add_stamps(IStamp stmp);double get_totalCommercialValue(); } Your classes (Stamp_GroupI, Stamp_GroupII and Philatelist) implementing the above two interfaces, as appropriate, should NOT have any other public method.The test file is as follows:class Program { static void Main(string[] args) { IPhilatelist john = new Philatelist("John"); IStamp w1= new Stamp_GroupII("Yellow Stone",0.29, 1975); IStamp w2 = new Stamp_GroupI("Forever Freedom",0.45, 2011); IStamp w3 = new Stamp_GroupI("Forever BigBen",0.42, 2008); john.add_stamps(w1); john.add_stamps(w2); john.add_stamps(w3); System.out.println("Total Commercial value is" + john.get_totalCommercialValue()); } }
