Question

Write a program that generates a random number and asks the user to guess what the number is. If the user's guess is higher than the random number, the program should display "Too high, try again." if the user's guess is lower than the random number, the program should display "Too low, try again." The program should use a loop that repeats until the user correctly guesses the random number. You shall also keep a count of the number of guesses that the user makes. When the user correctly guesses the random number, the program should display the number of guesses. Now add another loop to ask the user if he or she wishes to play the guessing game again. If so, the loop should repeat, otherwise it should terminate.So far, this is what my program looks like, any help or suggestions would be greatly appreciated!// This program generates a random number and askes the user to guess what the number isimport java.util.Scanner;import java.util.Random;public class GuessingGame{public static void main(String [] args){//Create a scanner object to read from the keyboardScanner kb = new Scanner(System.in);//Create a random objectRandom rand = new Random();//Identifier declarationsint num = rand.nextInt(100) + 1;int guess = 0;int count = 0;int guesses = 0;do{System.out.println("Guess what number I have (1-100)?

Answer:

import java.util.Scanner;

import java.util.Random;

public class Guesser {

// Create a scanner object to read from the keyboard

static Scanner kb = new Scanner(System.in);

// Create a random object

static Random rand = new Random();

public static void main(String[] args) {

 playGame();

}

public static void playGame() {

 // Identifier declarations

 int num = rand.nextInt(100) + 1;

 int guess = 0;

 int count = 0;

 int guesses = 0;

 do {

  System.out.println("Guess what number I have (1-100)? ");

  guess = kb.nextInt();

  guesses++;

  if (num > guess) {

   System.out.println("Too high, try again.");

  } else if (num < guess) {

   System.out.println("Too low, try again.");

  } else {

   System.out.println("You're right, the number is " + num);

   System.out.println("You guessed " + guesses + " times");

   //Ask the user if they want to play again

   //If yes, recursively call the playGame method again

   //Otherwise, break out of the loop

   System.out.println("Do you want to play again? (Y or N)");

   String answer = kb.next();

   if (answer.equalsIgnoreCase("Yes") || answer.equalsIgnoreCase("Y")) {

    playGame();

   }

   else {

    break;

   }

  }

 } while (guess != num);

}

}

Explanation:

There are a few things you need to do.

1. Make the creation of the objects of the Scanner and Random classes global. In other words, make them global variables.

2. Create a method, say playGame(), that is called, recursively, every time the user needs to play or replay the game.  

The source code file (Guesser.java) has been attached to this answer.

Note: You might want to consider also reducing the range of guess. I'd rather you reduced it to 1-10 rather than what you have. This will make the game much of a fun. With the range you currently have, the user might never guess right.

Hope it helps!
