How to set system.out.print caret at the same position?

[Camel]

Hello all,

I have a console program that prints numbers. I want the newly printed
number replace old number at the same position. How can do it?

Thank you very much in advance.

In general you can't. Java is not well suited for console/terminal
emulator/text applications. You can consider to use a JNI-based library
like JCurses to get more control over the console. Or you could play
with the control codes for your particular terminal emulation.

Try to print a "backspace" character with something like

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

Bye.

The System.out.print("\b") works.

Thank you two very much.
