How about creating a subclass that include the country and capital, and make an arrayList from those objects, so you will have to sort just for the countries and the capitals will be asociated to the same item.

public class MyObject
    {
        String country;
        String capital;

        public MyObject()
        {
            this.country = "";
            this.capital = "";
        }
        public MyObject(String newCountry, String newCapital)
        {
            this.country = newCountry;
            this.capital = newCapital;
        }

        public String getCapital()
        {
          return this.capital;
        }
        public String getCountry()
        {
            return this.country;
        }
    }

and then make an arraylist of this new object:

ArrayList<MyObject> myArray = new ArrayList<MyObject>();

fill the array, and when you sort, just made the same sorting you're using for the countries but with myArray.get(index).getCountry()
