Thread: JAVA HIGH LOW NUMBER GUESSING GAME

Alright guys so I am writing this program so that the computer creates a number and the user has to guess it by just high and low as a hint. It also has to keep track of the number of tries and output them in a JOptionPane, actually everything has to be a JOP. I have an error on my while statement hopefully I have given you all enough info to figure this out.

 
import java.math.*;
import java.util.Random;
import java.util.Scanner;
import javax.swing.*;
 
public class GuessingGame {
 
	/**

	 */
	public static void main(String[] args){ 
 
		// Variables
		String guess;
		int secretnum;
		int counter = 0;
		secretnum = (int) (Math.random()*1000+1);
		int thereguess = Integer.parseInt(guess);
 
		//Feel free to delete this. This is here so that you can have the number for testing
	    System.out.println("Secret number is "+ secretnum);
 
		//Loop in order to being checking input against 
	do { guess = JOptionPane.showInputDialog(null, "Please enter your number to guess:");
		counter++;
 
		if (thereguess == secretnum){
			counter++; 
			JOptionPane.showMessageDialog(null, "Your guess is correct congrats it only took you:"+ counter+ " tries");
			  break;
		}
		else if (thereguess < secretnum){
			counter++; 
			JOptionPane.showMessageDialog(null, "Your guess is to low try again"+ counter+ " tries");
		}
		else if (thereguess > secretnum){
			counter++; 
			JOptionPane.showMessageDialog(null, "Your guess is to high try again"+ counter+ " tries");
		}
		else if(thereguess< 0){
			counter++; 
			JOptionPane.showMessageDialog(null, "Good Job I Win-Thanks for playing. It took you:"+ counter+ " tries");
			System.exit(0);
		}
	  } 
    while(guess != secretnum);
 
	}	
}

my fault its says incompatible operand types Sting and int. now i think i discovered the reason why and its because I'm trying to compare a string to an int value and you can't do that. but now i don't know how to fix that. obviously i have to change guess to an Int but then when I do that i get a lot of errors. now hopefully i have given enough

Alright I moved that line in the do while statement and I still have the same error is there a chance that I have other issues with my code

Ok so now I have working code except when the user inputs a negative number I can't make the program quit.
