Question

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. USE JAVA

  1. starting latitude
  2. starting longitude
  3. ending latitude
  4. ending longitude

Then, using the GeoLocation class and our earlier example as a reference, 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: 48.8567

Enter the longitude of the starting location: 2.3508

Enter the latitude of the ending location: 51.5072

Enter the longitude of the ending location: 0.1275

The distance is 208.08639358288565 miles.
