How to replace 'n' back slashes with one in java

I would like to squeeze out 'n' number of slashes into 1, where n is not fixed.
For example:

String path = "Report\\\\\\n";

Expected output :

I tried the following way

System.out.println(path.replaceAll("\\+", "\");

But it's printing

I am not able to reduce more than that.

All the related so question/answer related to fixed number of slashes.

Is there any generic way I can squeeze all backslashes to one.?

If you print path, you'll get:


That's because \ should be quoted and it's written as \\ in Java.

You should do:

System.out.println(path.replaceAll("\\\\+", "\\\\"));
