How to replace and integer with another

[franzwarning]

Hi,

How would I display an integer, and then have it replaced with an integer that is one greater than the one before. So it is just a number counting up to lets say 4,000,000 ish.

Thanks,
George

A for loop could work well for this. What have you tried so far?

public class Strings{

public static void main(String args[]){
    double i = 0;
    int j = 1;

   while (i<4000000) {
       System.out.print(j);
       j++;
}

}
}

I just can't figure out how to have the next number replace the one before.

    int j = 1;

   while (i<4000000) {
       System.out.print(j);
       j++;
}

}
}

This loop will never end as i is never changed within the loop. A for loop would be better.

Please elaborate. What do you mean by "to have the next number replace the one before"?

I don't want the loop to end. I just want it to count so it will say "1" then the 1 will be replaced by a "2" which will be replaced by a "3".

Let's still try to clarify this. Are you saying that you want the console to display a 1, then the 1 disappears and is replaced by a 2, which disappears and is replaced by a 3? If this is the case, then forget it as consoles aren't built for this type of display and you'll be better off creating a Swing GUI to display your number.

Alright, thats all i needed to know. Just wanted to know if it was possible to do that in a console.

Yep. Console was the key word needed to answer this question.

Luck.
