如何打印到同一行? [英] How can I print to the same line?

问题描述

我想像这样打印进度条:

I want to print a progress bar like so:

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

但是这些都应该打印到终端的同一行而不是新的一行.我的意思是每个新行都应该替换前一行，而不是使用 print() 而不是 println().

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().

我如何在 Java 中做到这一点?

推荐答案

像这样格式化你的字符串:

Format your string like so:

[#                    ] 1%

注意 字符.就是所谓的回车，将光标移回行首.

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

最后，确保你使用

System.out.print()

而不是

System.out.println()
