In this exercise you will write a program to compute the distance between any two geo locations. In this program you will ask the user for four numbers. starting latitude starting longitude ending latitude ending longitude Then, using the GeoLocation class, compute the distance in miles between the two locations. A sample program run should match exactly as below: 1. starting latitude
2. starting longitude
3. ending latitude
4. ending longitude Doub
Then, using the GeoLocation class, compute the distance in miles between the two locations.
A sample program run should match exactly as below:
Enter the latitude of the starting location: 18.8567 Fara
Enter the longitude of the starting location: 23598
Enter the latitude of the ending location: 53 5872 dist
Enter the longitude of the ending location: 21275
The distance is 280 28639358788545 miles.

2 This class stores information about a location on Earth. Locations are
3 specified using latitude and longitude. The class includes a method for
4 computing the distance between two locations.

6 This implementation is based off of the example from Stuart Reges at
7 the University of Washington.
