[英]Remove all other trailing whitespace characters except tab in Java
I know that removing whitespaces is as easy as String.trim(). 我知道删除空格就像String.trim()一样简单。 But my string contains tab (\\t) characters which I would like to keep.
但我的字符串包含我想保留的tab(\\ t)字符。
Example: 例:
"teststring\t\t\t ".trimSpaceNotTab() => "teststring\t\t\t"
My current implementation is to use split(); 我目前的实现是使用split();
String[] arr = tabbedString.split("\t");
Then joining them somewhere as a string. 然后将它们作为字符串连接到某处。
I find this implementation slow and ugly. 我发现这个实现缓慢而丑陋。
Is there a better way in Java where I can retain the tabs? 在Java中有更好的方法可以保留标签吗?
How about 怎么样
tabbedString.replaceAll("[ \n\x0B\f\r]","")
Function used - String.replaceAll()
使用的函数 -
String.replaceAll()
In case you'd like to also go for tabs and remove them, use a predefined character class \\s
如果您还想去标签并删除它们,请使用预定义的字符类
\\s
浏览字符串并使用isSpaceChar询问每个Char是否有空格
使用替换所有空格但不替换制表符(\\ t)的正则表达式。
