                else
                    if (a < b)
                    {
                        c.println (a + " is less that " + b);
                    }
                    else

                        if (a == -999)
                        {
                            break;
                        }
        }
        while (a > b && a == b && a < b || a != -999);
    }
}

I want my program to end when i enter the number -999. Can you tell me what i'm doing wrong? i don't wanna change and of the following:

(Toggle Plain Text)

import java.awt.*;
import hsa.Console;
public class comparism
{
    static Console c = new Console ();
    static public void main (String[] args)
    {

can someone help me?

Mmm.. in the while put just a!=-999. like this: while(a!=-999).
Also, the last if .. i don't think it's necesary after that.

(Toggle Plain Text)

a > b && a == b && a < b

that will always evaluate to false,

if a <b then a !> b

if a == b etc etc etc so that statement is not required, just is

while(a != -999)

and yes the last if else is not required :/ just you had that odd thing in your while loop.

        c.clear ();
        do
        {
            c.print ("A = ? ");
            a = c.readInt ();
            c.print ("B = ? ");
            b = c.readInt ();
            if (a > b)
            {
                c.println (a + " is geater than " + b);
            }
            else if (a == b){
                    c.println (a + " equals to " + b);
            }
            else if (a < b){
                    c.println (a + " is less that " + b);
            }
       }
        while (a != -999);
    }
}

or, if you want to exit faster, put if(a==-999)break; - before if(a>b)
