yeah

for example.. when you do a scandisk of your hard drive.. do you see that percentage number that goes from 0 to 100? when its 0 it changes to 1 then 2 then 3 when it reaches 9 it adds another digit, so now its 10 11 and so on but on the same place in that line.. can you get it now?

:-/

please tell me you're not talking about this:for(int i = 0; i <= 100; ++i) {System.out.println(i);}

No, I think he wants each subsequent printed number to overwrite the previous number. So instead of

he wants to only show one number at a time when the loop increments. The other number should disappear.

when you use a for like that right... once u start if(i < 10) for example.. then it will print like this:

and so on.. right? well i dont want it that way i want it like if it was a percentage bar when u install a program.. you have a bar that ||||||||| increases as the installation goes on.. but u also have a number inside the bar that says in numbers how the installation is going..

check this to see what i'm trying to tell :-/

Kinda like this?

public class PrintfTest {

public static void main(String[] args) {

for (int i = 0; i < 100; i++) {

System.out.printf("%7d", i);

try {Thread.sleep(100);} catch(InterruptedException swallowMe) {/* gulp */}

System.out.print("\b\b\b\b\b\b\b");

}

Yes. No one knows whether you're talking about a javascript manipulation of a web page, a console application, or a Swing progress bar widget.

lol

ok my bad!!! :-/

its a console application.. the number i want to display has to go from 0 to 100 in the same place where it is .. for example it starts with a 0, then when i increase the number, 0 is erased and 1 shows up in the same place where the 0 was..

now when you get to 9 you are about to change from a 1 digit to a 2 digit number.. 10.. this time the 0 next to the 1 will change to 1 so it will be a 11 and so on.. :-/

So, kinda like this?

public class PrintfTest {

public static void main(String[] args) {

for (int i = 0; i < 100; i++) {

System.out.printf("%7d", i);

try {Thread.sleep(100);} catch(InterruptedException swallowMe) {/* gulp */}

System.out.print("\b\b\b\b\b\b\b");

}

Sorry for "hijacking" this thread...but I was wondering if there was any way to clear the console in java; so instead of using backspaces and then printing the number again, could you clear the console screen instead and then reprint the incremented number?
