public class RoadTrip { }

In this problem we are going to use ArrayLists and classes to design a road trip. You have three classes: Geolocation.java from earlier, which represents a geo location. A Roadtrip.java class which represents a road trip (or an ordered list of places), and a Roadtriptester.java class which brings them all together. In GeoLocation.java: Add a private instance variable called name which is a String. This represents the name of the location. Modify the Geolocation class constructor so that it is now of the format public GeoLocation(String name, double theLatitude, double theLongitude) Add a getter method for name called getName(). Update the toString so that it returns a String of the format San Francisco (37.7833, -122.4167) Now, you'll also need to create a Road Trip class. The Road Trip stores an ordered list of locations, so you'll need to have an ArrayList. You'll also need to support these methods. // Create a GeoLocation and add it to the road trip public void addstop(String name, double latitude, double longitude) // Get the total number of stops in the trip public int getNumberofstops() // Get the total miles of the trip public double getTripLength() // Return a formatted tostring of the trip public String toString() We've given you a tester program to help get you started. The output from that program would be: 1. San Francisco (37.7833, -122.4167) 2. Los Angeles (34.052235, -118.243683) 3. Las Vegas (36.114647, -115.172813) Stops: 3 Total Miles: 572.9708850442705
