Need help with a guessing game

Question

Hi. hopefully, this is a really easy issue to resolve. I had to write a program that administers a guessing game, where the computer chooses a random number, and the user has to guess the number. If the user doesn't get it within 5 guesses, they lose and start all over with a new number. I have this all in a while loop (as per my instructions). My issue is that whenever the user enters 0, the program should quit with the users final score and so on. My program will not quit unless the 0 is entered on the last (fifth) guess. please help, it would be very appreciated. Here is my code:
import java.util.Scanner;
  public class guessgame {
    public static void main(String[] args) {
      Scanner scanner = new Scanner (System.in);
        int randnum;        //random number generated by computer
        int userguess = 1;      //number the user guesses
        int userscore = 0;      //number of correct guesses by user
        int compscore = 0;      //number of times not guessed
        int guessnum = 0;       //number of guesses for one number
        int gamenum = 0;        //number of games played
    System.out.println ("I will choose a number between 1 and 10");
    System.out.println ("Try to find the number using as few guesses as possible");
    System.out.println ("After each guess i will tell you if you are high or low");
    System.out.println ("Guess a number (or 0 to quit)");
    while (userguess != 0) {
      randnum = 1 + (int)(Math.random() * 10); //generates random number
      gamenum ++;
      userguess = userguess;
        for (guessnum = 1; guessnum < 6 && userguess != randnum; guessnum ++) {
            userguess = scanner.nextInt();
            userguess = userguess;
           if (guessnum >= 5) {
              System.out.println ("You did not guess my number!");
                              } //closes if statement
           if (userguess == randnum) {
             userscore ++;
             System.out.println ("You guessed it! It took you " + guessnum + " tries.");
             System.out.println ("If you want to play again, enter a guess");
             System.out.println ("If you do not want to play again, enter 0");
                                    } //closes if statement
           else if (userguess < randnum)
             System.out.println ("Your guess is too low");
           else if (userguess > randnum)
             System.out.println ("Your guess is too high");
                                                      }//closes for loop
                          } //closes while loop
compscore = gamenum - userscore;
        System.out.println ("Thanks for playing! You played " + gamenum + " games");
        System.out.println ("Out of those " + gamenum + " games, you won " + userscore + " times");
        System.out.println ("That means that I won " + compscore + " times"); 
} //closes main
} //ends guessgame class

Answer 1

The problem with your program is that the while loop doesn't get checked. The condition of the while loop will only get checked each iteration, and not during one iteration. The time you are in your for-loop is still one iteration so it won't check if userguess is 0. see it liek this
While: is userguess 0, no, do 1 iteration
while-iteration-forloop: check 5 guesses, userguess can be anything even 0 while loop won't stop.
end of for loop
end of while-iteration
new while iteration, is userguess 0?
and so on.
