Question

Im brand new to java, and I’m writing this short program where you guess a number between 1 and 10. The correct number is stored as an integer. If you guess a lower number, its supposed to say “The correct number is higher”, and if you guess a higher it should say “The correct number is lower”. Here’s what I have:

    import javax.swing.*;

public class Oppg3 {
    public static void main(String[] args) {
        int number = 7;
        int guessed = Integer.parseInt(JOptionPane.showInputDialog("Guess a number between 1 and 10"));
        while(guessed>number) guessed = Integer.parseInt(JOptionPane.showInputDialog(guessed + " is wrong. Try a lower number."));
        while(guessed<number) guessed = Integer.parseInt(JOptionPane.showInputDialog(guessed + " is wrong. Try a higher number."));
        JOptionPane.showMessageDialog(null, guessed + " is correct!");

    }

}

So obviously that wont work, cause if you enter a lower number it’ll jump to the next one, and that will come up as correct even if its higher. So how do I fix this so that it’ll check for both statements? Sorry for bad explaining. Thanks.

The simplest solution is to replace your current whiles with ifs, and contain them both in a

while(guessed!=number)
{
    if(guessed>number) //stuff
    if(guessd<number) //otherstuff
}
