Hi i'm supposed to make a number guessing game that does the following:

Quote:

What is your guess? (from 0 to 10) ? 8
That is wrong, try again. (Output this line in red - use a sound to signal the wrong answer)

What is your guess? (from 0 to 10) ? 5
That is wrong, try again.

What is your guess? (from 0 to 10) ? 4
That is right, it took 3 tries. (Output this line in green - use a sound to signal the correct answer)

This is how far i got:

(Toggle Plain Text)

import java.awt.*;
import hsa.Console;
public class guess
{
    static Console c = new Console ();
    static public void main (String[] args)
    {
        int g1;
        c.clear ();
        for (int x = 1 ; x <= 10 ; x++)
        {
            c.setTextColor (Color.black);
            c.print ("What is your guess? ");
            g1 = c.readInt ();
            if (g1 != x)
            {
                c.setTextColor (Color.red);
                c.println ("That is wrong, try again.");
                c.println ();
            }
            else
                if (g1 == x)
                {
                    c.setTextColor (Color.red);
                    c.println ("That is right, it took you " "tries.");
                }
        }
    }
}

can someone help me?

why use a for loop?
why not use Random class?
thn compare the input with the generated num...

Or Math.rand() (I believe that is a real method).

Well i haven't learned any of those yet. Otherwise i would use em.

something like this should work:

(Toggle Plain Text)

Random value = new Random();
value = Math.abs(value.nextInt % 10 + 1);

What do you mean by :

use a for(;; ) loop. If x is what you'r trying to guess, stop incrementing it in your for loop. Do something like:

(Toggle Plain Text)

int i=0;
for(;;){
     if(gl==x){
        i++;
        System.out.println("Yeaapyy u found the number"+gl+"in"+i+"tries");
        break;
     }
     else {
           System.out.println("The number you entered is wrong");
           i++;  // this will give you the number of tries. Initiate it with 0 first
     }
}

That Console reader doesn't work on my comp. so you could try :

(Toggle Plain Text)

static BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

Also use the example given by Childe Roland to generate your number

Good luck!

edit: for(;

- damn formating

Maybe i'm doing it wrong but its not working.

this is what i got so far:

(Toggle Plain Text)

import java.awt.*;
import hsa.Console;
public class guess
{
    static Console c = new Console ();
    static public void main (String[] args)
    {
        int g1;
        c.clear ();
        for (int x = 1 ; x <= 10 ; x++)
        {
            c.setTextColor (Color.black);
            c.print ("What is your guess? ");
            g1 = c.readInt ();
            int i = 0;
            for (;;)
            {
                if (gl == x)
                {
                    i++;
                    System.out.println ("Yeaapyy u found the number" + gl + "in" + i + "tries");
                    break;
                }
                else
                {
                    System.out.println ("The number you entered is wrong");
                    i++;
                }
            }
        }
    }
}

Hey, listen, I personaly think that you have no ideea about what you'r doing. You just copyed the bit I gave; think for a change.

Honestly, .. go study....

Childe Roland · Apr 3rd, 2005, 6:56 AM

i think what you should do is get a piece of paper and write out the logic of your program and see what it is that you have x doing.

I'm not really sure if you want it to do what it is doing and that can throw of the rest of your program.

whats a for(;; ) used for?
