Help with slash and back slash

Question

hi guys
I'd like to replace / with \ in a string like that
c:\myfolder\myexamples\myfile.txt to c:/myfolder/myexamples/myfile.txt
so I can use runtime exec

Answer 1

Nobody seems to have noticed that the original
question was something like
"I want to change / to \ in a String so that the
resulting String will have / instead of \ in
it."
I noticed. I assumed he meant what the example demonstrated, not what the prose stated.
However, on re-reading it, he says it's to be able to use Runtime.exec, so probably he wants replaceAll("\\\\", "\\\\\\\\").
Or does runtime.exec accept "C:/a/b/c.exe"?

Which if you look carefully, doesn't make sense.
Everybody provided a method to change \ to /, even
though the subtext of the post suggested that
changing / to \ was the real requirement. Which would
beString str2 = str.replaceAll("/",
"\\\\");At least it would to somebody like me
who doesn't know regular expressions well. I would
use the simple, non-regex version:String str2 =
str.replace('/', '\\');
