Question

I want to print a progress bar like so:

[#                    ] 1%
[##                   ] 10%
[##########           ] 50%

But these should all be printed to the same line in the terminal instead of a new one.
What I mean by that is that each new line should replace the previous, it’s not about using print() instead of println().

How can I do that in Java?

Answer 1

Format your string like so:

[#                    ] 1%\r

Note the \r character. It is the so-called carriage return that will move the cursor back to the beginning of the line.

Finally, make sure you use

System.out.print()

and not

System.out.println()
