换行符可能不是"\n"
""

因为replaceAll是正则表达式，所以两次转义

I tried
s = infile.readLine()
s = infile.readLine().replaceAll("\\n+", "")
s = infile.readLine().replaceAll("[\n\r\t]+", "")
s = infile.readLine().replaceAll("\r\n|\r|\n", "")
s = infile.readLine().replaceAll("\\n", "")
It's very strange that none of them work. |

the entire file as a string.

发帖数: 12623 | 8 不要用replaceAll。用replace就行啦：
str.replace("\n", "") |
