Java program to calculate the commercial value of the stamps, JAVA Programming

Assignment Help:

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());

}

}
