Question

[Java] Write a program that stores pairs of all the states and capitals (USA). The program should give the user a State and ask for the capital. The program should keep track of how many correct answers were given. User should see score printed at the end. IMPORTANT: Make sure the program RANDOMLY asks for the capital of a random state. This question has already been asked before in Expert Q&A but the answer never randomly gave states.

=================================

// StatesCapitals.java

import java.util.Scanner;

public class StatesCapitals {

   public static void main(String[] args) {
       /*
       * Creating an Scanner class object which is used to get the inputs
       * entered by the user
       */
       Scanner sc = new Scanner(System.in);
       // Declaring variables
       int cnt = 0;
       int index;
       String ans;
       // Declaring and initializing an array
       String states[] = { "Alabama", "Alaska", "Arizona", "Arkansas",
               "California", "Colorado", "Connecticut", "Delaware", "Florida",
               "Georgia", "Hawaii", "Idaho", "Illinois", "Indiana", "Iowa" };

       String capitals[] = { "Montgomery", "Juneau", "Phoenix", "Little Rock",
               "Sacramento", "Denver", "Hartford", "Dover", "Tallahassee",
               "Atlanta", "Honolulu", "Boise", "Springfield", "Indianapolis",
               "Des Moines" };

       for (int i = 0; i < 5; i++) {
           index = (int) (Math.random() * ((states.length-1) + 1));
           System.out.print("What is the Capital for \"" + states[index]
                   + "\" ? :");
           ans = sc.nextLine();
           if (ans.equalsIgnoreCase(capitals[index])) {
               System.out.println("Correct!");
               cnt++;
           }
           else
           {
               System.out.println("Wrong.The answer is : "+capitals[index]);
           }

       }

       System.out.println("Out of 5 no of correct answers :" + cnt);

   }

}
