General :: Printing To A Progress Bar To The Terminal From Java/C++ - Stack Overflow?

I want to update the percentage progress of my program on the screen. I have a progress bar that I print. I add a * when the progress is more than 10%, but I also want to write the actual percentage correct up to every digit. However, I do not want to write a new number every time, since it will have the following effect:

1
2
3
4

Instead, I would like to just maintain one single figure on the screen that keeps getting updated. How do I do that? (... in Java/C++, but I think it's irrelevant)
