Country.java

 class Country{
     static String countryName;
     static String gold;
     static String silver;
     static String bronze;
     static  String totalMedals; 

    public Country(String countryName, String gold, String silver, String bronze, String totalMedals)
    {
        this.countryName=countryName;
        this.gold=gold;
        this.silver=silver;
        this. bronze = bronze;
        this. totalMedals = totalMedals;
    }
    public static String getName()
    {
        return countryName;
    }

    public static String getGold()
    {
        return gold;
    }

    public static String getSilver()
    {
        return silver;
    }

    public static String getBronze()
    {
        return bronze;
    }

    public static String getTotalMedals()
    {
        return totalMedals;
    }

}

MedalTally.java

import java.util.*;

public class MedalTally 
{

  ArrayList<Country> list;

  public MedalTally()
  {
    list = new ArrayList<Country>();
  }

  public void addEntry(Country x)
  {
    list.add(x); 
  }


  public void write() throws java.io.IOException
  {

     FileWriter fw = new FileWriter("olympics.txt", true);
     PrintWriter write = new PrintWriter(fw);
     for(int index =0; index < list.size(); index++)
    {
      Country x = list.get(index);
      write.println(x.getName()+" "+x.getGold()+" "+x.getSilver()+" "+x.getBronze()+" "+x.getTotalMedals());
      write.close();
