Question

Magic 8 Ball(JAVA)
A magic 8 ball is a popular fortune telling toy in which the user places the ball face down, asks a
yes-or-no question and turns the ball face up to reveal the answer.
The standard magic 8 ball has 20 standard answers shown below, where 10 are positive (green),
5 are non-committal (yellow), and 5 are negative (red) (credit: Wikipedia)
Write a program that does the following:
1. Stores all the responses in a String array using an initializer list.
2. Generates a random number for the responses using a random object (in the range 0 to 19)
3. Prompts the user to enter a question.
4. Uses the random number to access and display the corresponding response (example: if the
random number generates 4 it should display “You may rely on it.”)
5. Asks the user if they want to ask another question (using a do – while loop). The code should
repeat as long as the user says “yes”.
A sample of the output are shown below:
What is your question? Will John get me some Panera tomorrow?
Reply hazy, try again.
Would you like to ask another question? (Answer yes or no): yes
What is your question? Will my dog become an instagram star?
Yes.
Would you like to ask another question? (Answer yes or no): yes
What is your question? Will I pass this class if I study hard?
Without a doubt.
Would you like to ask another question? (Answer yes or no): no
Notes:
• Use the equalsIgnoreCase method to accept any version of the word yes. You can use it
like str.equalsIgnoreCase(“yes”) where str is a variable of type string.
• You may have to deal with the annoying problem of capturing the [Enter] that is pressed
between responses. Remember, you can capture it with an extra nextLine method – but
be sure to put it in the right place!

// Java program to implement the Magic 8 ball popular fortune telling toy
import java.util.Random;
import java.util.Scanner;

public class Magic8Ball {

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);
       // array to store 20 repsonses
       String responses[] = {"Yes.","Reply hazy, try again.","It is certain.","No.","Most likely.","Without a doubt.","Don't count on it.","You may rely on it.","It is decidedly so.","Ask again later.","Yes definitely.","As I see it, yes.","Signs point to yes.","Cannot predict now.","Concentrate and ask again.","My sources say no.","Outlook not so good.","Very doubtful.","Better not tell you now.","Outlook good."};
       String question;
       String contRes;
       int index;
      
       Random ran = new Random();
       // loop that continues till the user wats
       do
       {
           // input the question
           System.out.print("What is your question? ");
           question = scan.nextLine();
           // randomly generate the index of response
           index = ran.nextInt(responses.length);
           // display the response
           System.out.println(responses[index]);
           // ask the user if he wants to ask another question
           System.out.print("Would you like to ask another question? (Answer yes or no): ");
           contRes = scan.next(); // read the response
           scan.nextLine(); // ignore the enter
       }while(contRes.equalsIgnoreCase("yes"));
  
       scan.close();
   }

}
//end of program
