    Default A little help please =D

    So I got this far

    import javax.swing.JOptionPane;

    public class GuessingGame {
    public static void main (String [] args) {

    int num1 = (int) (System.currentTimeMillis()%10);

    String answerString = JOptionPane.showInputDialog(null,"Guess a number between 1 and 10");
    int answer = Integer.parseInt(answerString);

    if (answer > num1)
    JOptionPane.showMessageDialog(null,"Your answer is too high");
    else if (answer < num1)
    JOptionPane.showMessageDialog(null, "Your answer is too low");
    else
    JOptionPane.showMessageDialog(null, "You won!");

    }
    }

    This program I am making is a guessing game. The user needs to guess a number between 1 and 10. If the user guesses too high or too low then try again. How do I make the user try again without starting over? Anyone want to give me hints and I try my best to solve it. I was going to make the last part of the program look like this but I don't know.

    if (answer > num1)
    JOptionPane.showMessageDialog(null,"Your answer is too high");
    String answerString = JOptionPane.showInputDialog(null,"Guess a number between 1 and 10");
    int answer = Integer.parseInt(answerString);

    else if (answer < num1)
    JOptionPane.showMessageDialog(null, "Your answer is too low");
    String answerString = JOptionPane.showInputDialog(null,"Guess a number between 1 and 10");
    int answer = Integer.parseInt(answerString);

    else
    JOptionPane.showMessageDialog(null, "You won!");

    This gave me errors and I don't think this is the right way to do it. NO LOOPS =D

    In the future, could you please surround your code in CODE tags, such as the ones found in my signature.
    Is there a reason you don't want to use loops? As It will tidy up your code a lot more than if you were to go down the route of ifs.

    By using a loop, it can endlessly re-prompt the user for an answer by sticking to a single true/false condition, whereas if's get messy.
    Also be sure to always surround your if, if-else blocks with braces as It shows the execution path clearer and makes the code easier to read.

    Additionally, look into the Random class from the Java API, specifically nextInt(int n) to generate a random number, as your approach could generate zeros as well.

    Please use [highlight=Java]//code goes here...[/highlight] tags when posting your code

    The only reason why I don't want to use a loop is because my teacher doesn't want us to use a loop. =(
    I barely joined this website today and I am still getting use to it. When I paste my code in do I put [*Code in here*] in those brackets so everyone knows which is part of the code?

    On General note whenever you write Game there is suppose to be a Game thread which is an while loop continuously running until game is over or stopped, in this loop you check condition, take action and forward the game. you probably would like to structure your program like that.

    At the end and beginning of your code, example
     CODE HERE
    I did this, without the spaces
    [ code]
    your code here
    [/code ]
    It's hard to read your code with out that, if you put it in the correct format perhaps I could help.
