Java I need to modify this code so that I am using a dialogu

Java I need to modify this code so that I am using a dialogue box instead of scanner and I have no idea where to start. I am supposed to use showInputDialog() and showMessageDialog() to get the input and produce the output of GuessANumber. This is what I have so far.

import java.util.Random;
import java.util.Scanner;
public class GuessANumber //First, name the new class, and .java file, GuessANumber_yourinitials.
{
public static void main (String[] args)
{
//Then, create an object of the Random class and call the nextInt() method to generate random number from 1 - 1000.
//Be careful to generate the correct range - not 0 to 999. Now you have the number that the player has to guess.
Random rand = new Random();
int numberToGuess = rand.nextInt(1000);
int numberOfTries = 0; //Add an int variable to keep up with the number of guesses, and start it off at 0.
int guess;
Scanner input = new Scanner(System.in);
boolean win = false;
  
while (win == false) //loop until correct answer is guessed
{
System.out.println(\"Guess a number between 1 and 1000: \"); //Add a statement to prompt the user to enter a guess between 1 and 1000.

guess = input.nextInt();//Now, user Scanner and nextInt() to read the guess.
numberOfTries++; //Update the count on the number of guesses
  
if (guess == numberToGuess) //User conditionals to let the user know if the guess is too low, too high or CORRECT!
{
win = true;
}
else if (guess< numberToGuess)
{
System.out.println();
System.out.println (\"The number you guessed is too low please \");
}
else if (guess > numberToGuess)
{
System.out.println();
System.out.println (\"The number you guessed is too high please \");
}
  
}
System.out.println(\"You win!\");
System.out.println(\"The number was \" + numberToGuess); //output the correct answer and the number of tries
System.out.println(\"It took you \" + numberOfTries + \" Tries\");
}
}

Solution

Hi,

I have modified your code. it is working fine as expected. Highlighted the code changes below.

GuessANumber.java

import java.util.Random;

import javax.swing.JOptionPane;
public class GuessANumber //First, name the new class, and .java file, GuessANumber_yourinitials.
{
public static void main (String[] args)
{
//Then, create an object of the Random class and call the nextInt() method to generate random number from 1 - 1000.
//Be careful to generate the correct range - not 0 to 999. Now you have the number that the player has to guess.
Random rand = new Random();
int numberToGuess = rand.nextInt(1000);
int numberOfTries = 0; //Add an int variable to keep up with the number of guesses, and start it off at 0.
int guess;
// Scanner input = new Scanner(System.in);
boolean win = false;
  
while (win == false) //loop until correct answer is guessed
{
//System.out.println(\"Guess a number between 1 and 1000: \"); //Add a statement to prompt the user to enter a guess between 1 and 1000.

guess = Integer.parseInt(JOptionPane.showInputDialog(\"Guess a number between 1 and 1000: \"));
numberOfTries++; //Update the count on the number of guesses
  
if (guess == numberToGuess) //User conditionals to let the user know if the guess is too low, too high or CORRECT!
{
win = true;
}
else if (guess< numberToGuess)
{
// System.out.println();
JOptionPane.showMessageDialog(null, \"The number you guessed is too low please \");
//System.out.println (\"The number you guessed is too low please \");
}
else if (guess > numberToGuess)
{
// System.out.println();
JOptionPane.showMessageDialog(null, \"The number you guessed is too high please \");
//System.out.println (\"The number you guessed is too high please \");
}
  
}
JOptionPane.showMessageDialog(null, \"You win!\ The number was \" + numberToGuess+\"\ It took you \" + numberOfTries + \" Tries\");
// System.out.println(\"You win!\");
// System.out.println(\"The number was \" + numberToGuess); //output the correct answer and the number of tries
// System.out.println(\"It took you \" + numberOfTries + \" Tries\");
}
}
