在java中使用printf换行?%n 正确吗? [英] Taking a new line using printf in java? Is %n correct?

问题描述

这里是新手，但我最终无所适从.我已经让我的程序全部正常工作，但在打印时只需要格式化方面的帮助.

newbie here but I am at my wits in end. I have got my program all to work but just need help with the formatting when printing out.

if(count == 3)
    System.out.printf ("%-15s %15s %15s %15s %15s %n", n, " is compatible with 
                         ",dates[k],dates[k+1],dates[k+2]);

我的输出是

Stacey Francis   is compatible with     Owen Farrell   Jack Clifford  Joshua Watkins 

我希望我的输出是(不重复 stacey francis 的名字或与"兼容:

I would like my output to be (without repeating stacey francis name or "is compatible with":

Stacey Francis   is compatible with  Owen Farrell

                          Jack Clifford

                          Joshua Watkins

只是想知道如何解决这个问题?

Just wondering how to go about this?

谢谢，

推荐答案

是的，%n 是 printf 中的换行符.请参阅 java.util.Formatter 的文档，特别是指定的转换表:

Yes, %n is a newline in printf. See the documentation of java.util.Formatter, specifically the conversion table which specifies:

'n' 行分隔符 结果是平台特定的行分隔符

'n' line separator The result is the platform-specific line separator

您的输出当前仅在结尾处有一个换行符，而不是您似乎想要它们的位置.您需要使用如下格式:

Your output currently only has a linebreak at the end, not at the points that you seem to want them. You would need to use a format like:

"%-15s %15s %15s %n %15s %n %15s %n"

(可能还有一些标签用于对齐).

(and maybe some tabs thrown in there for alignment).
