how to print output on same line in 'while loop'?

[acidblue]

I have a 'while loop' that prints on a new line everytime;
system.out.println("bla bla bla:" + N)
output i have:
count 1
count 2
count 3......and so on

what i want to do is print on the same line and display the count in real time,
instead of on a new line.

using 'print' instead of 'println' prints every thing all in one long line.
I imagine i could clear/erase the line and print a new line in the 'while loop'
but not sure how to do that.
output i want:
count x: have the numbers change in realtime instead of on a new line.

right now it's a command line program but want to update to a gui/pop up box.

When you upgrade to a GUI, you will abandon System.out.println all together. The text box that you use inside of your GUI will have a text attribute and you will change that instead of printing the text. If I were you, I wouldn't worry about making this change when you are still running from the command line.

thanks for the reply.
but to cure my curiosity was i at least on the right track?
would still like to try it.

No, there is no way to change something that has already been printed to the console. Not unless you use some sort of a native library, java cant do that.

If you'd really like to try it, you could use the Curses for Java library... On SourceForge, but it hasn't been updated in five years - meaning either it's that good, or it's unsupported. I've used ncurses in C, never tried this in Java... Like is mentioned above, I go straight to the UI.

Or the other solution is to create a wrapper with JNI, but for that you need quite a bit of Java AND C or C++ knowledge.
