Question

Goal: Write a simple number guessing game in java.

1. The game picks a number between bounds input by the user, then user has to guess the number.

2. The game will tell you if your guess is too high or too low.

3. When you guess it, the game will tell you how many guesses it took

4. Run multiple games and print statistics (# games, # guesses, avg) when all done.

Sample Run:

G U E S S I N G G A M E !

Enter lower and upper bounds:

1

10

Enter a number from 1 to 10 (inclusive):

5

Correct, the number was 5! You got it in 1 tries.

Again? (yes or no):

yes

Enter a number from 1 to 10 (inclusive):

5

Too high...

Enter a number from 1 to 10 (inclusive):

3

Correct, the number was 3! You got it in 2 tries.

Again? (yes or no):

no

You played 2 games and made 3 guesses total (1.5 guesses per game).

import java.util.Scanner;
import java.util.Random;
class ex{
   public static void main(String[] args) {
       Scanner scnr=new Scanner(System.in);
       Random rand=new Random();
       System.out.println("G U E S S I N G G A M E ! ");
       System.out.println("Enter lower and upper bounds:");
       int min=scnr.nextInt();
       int max=scnr.nextInt();
       float games=0,guesses=0;
       String choice="yes";
       while(choice.equals("yes")){
           int userGuess=0;
           int tries=1;
           int rand_int=rand.nextInt((max-min+1))+min;
           while(userGuess!=rand_int){
               System.out.println("Enter a number from "+min+" to "+max+" (inclusive):");
               userGuess=scnr.nextInt();
               ++tries;
               guesses=guesses+1;
               if(userGuess==rand_int){
                   System.out.println("Correct,the number was "+rand_int+"!you got it in "+tries+" tries.");
                   break;
               }
               else if(userGuess<rand_int)
                   System.out.println("Too low...");
               else if(userGuess>rand_int)
                   System.out.println("Too high...");
           }
           System.out.println("Again?(yes or no):");
           choice=scnr.next();
           games=games+1;
       }
       System.out.println("You played "+games+" games and made "+guesses+" guesses total("+(guesses/games)+" guesses for game).");
       System.out.println("T H A N K S F O R P L A Y I N G !");
   }
}
