Write the program in Java.

Exercise 1. (Great Circle Distance) Write a program GreatCircle.java that takes four doubles X1, yi, X2, and y2 representing the latitude and longitude in degrees of two points on earth as command-line arguments and writes the great-circle distance (in km) between them, given by the equation d= 111 arccos(sin(x1) sin(22) + cos(x1) cos(x2) cos(y1 - y2)). import stdlib.Stdout; public class Great Circle { // calculates the great circle distance given two sets of coordinates protected static double calculateGreat CircleDistance (String[] args) { // Get angles lati, loni, lat2, and lon2 from command line as // doubles. // Convert the angles to radians. // Calculate great-circle distance d. // Return d. // Entry point. [DO NOT EDIT] public static void main(String[] args) { Stdout.println (GreatCircle.calculateGreat CircleDistance (args))
