How to remove the backslash in string using regex in Java?

Question

How to remove the backslash in string using regex in Java?

For example:

hai how are\\ you?

I want only:

hai how are         


        

Answer 1

str = str.replaceAll("\\\\", "");

or

str = str.replace("\\", "");

replaceAll() treats the first argument as a regex, so you have to double escape the backslash. replace() treats it as a literal string, so you only have to escape it once.
