java - Is it possible to replace leading zeroes in a string with an equal number of spaces using replaceAll()? -


in java, i'm trying replace strings "001.234" "spacespace1.234". however, i'm regex noob , seem ending leading zeroes replaced single space.

i understand can loop i'm trying pick regular expressions , appreciate :)

no problem:

string resultstring = subjectstring.replaceall("\\g0", " ");

\g acts \a (the start-of-string anchor) on first iteration of replaceall(), on subsequent passes anchors match spot previous match ended. prevents matching zeroes anywhere else in string, after decimal point.
