    You can use an ArrayList.

    ArrayList listOfObjects = new ArrayList();



    And then add items to it.
    


    listOfObjects.add("1");
listOfObjects.add(someObject);

    


    Or create your own object that encapsulates all the field that you require like
    


    public class LocationData {
   private double lat;
   private double longitude;

   public LocationData(double lat, double longitude) {
       this.lat = lat;
       this.longitude = longitude;
   }
   //getters
   //setters
}

    


    and then add your lat/long pairs to an ArrayList of type LocationData
    


    ArrayList listOfObjects = new ArrayList();

listOfObjects.add(new LocationData(lat, longitude));
