Hey guys i need u to see if this program is runnign properly. I want it to show 20 random numbers between 5 and 10. Mutiple numbers allowed. If u think something is wrong, please let me know

what's with all of the for loops?

Berto · Apr 6th, 2005, 3:48 AM

(Toggle Plain Text)

for (;;) = infinate loop

Ooble · Apr 6th, 2005, 4:26 PM

I think he's saying, what's the point of them if you're breaking out on the first instance?

Childe Roland · Apr 6th, 2005, 4:32 PM

your code but there a few changes you should make to it.
the way it is set up it the highes number it will generate it a 9.
also you really don't need all those seperate for ( ;;; ) statements and 20 different variables you can do the same thing with just one variable and one for loop
like i did below.

(Toggle Plain Text)

import java.awt.*;
import hsa.Console;

public class Random1
{
	static Console c = new Console (5, 20);
	public static void main (String [] args)
	{ 
		int x;
 
 		x = (int) (Math.random () * 6) + 5;
 		c.print (x);
 
 		for(int i = 1; i < 20; i++)
   		{
	  			x = (int) (Math.random () * 6) + 5;
	  			c.print (x ,5);
			}
	}
}

thanks. i just figures that out this morning

Gigabytee · Apr 8th, 2005, 4:40 AM

hay,
I know the question is well answered but i had another (subqustion)
how did u limit the Random Numbered (under 10)
I would normally add a while loop there "while(x>9)" or something like that...

(Toggle Plain Text)

public class Random1
{
	public static void main (String [] args)
	{ 
		int x=10;
 		for(int i = 0; i < 20; i++)
   		{
   				x = (int) (Math.random () * 8) + 4;
	  			while(x>9)
	  				x = (int) (Math.random () * 8) + 4;
	  			System.out.println(x);
			}
	}
}

Childe Roland · Apr 8th, 2005, 12:23 PM

you could do it the way you are doing but it could take a while to actually get a number that is less then 10 sometimes. it maybe better to change this part

(Toggle Plain Text)

(int)(Math.random () * 8) + 4;

the way it is now it generates numbers between 4 and 11

if you wanted them to stay under 10 try

(Toggle Plain Text)

(int)(Math.random () * 7) + 4
