String.replaceAll() is not working

Question

I am editing some email that got from tesseract ocr.

Here is my code:

 if (email != null) {
        email = email.replaceAll(\" \",         


        

Answer 1

I think you are not aware that first parameter of replaceAll is regex.

. , |, } might be interpreted in a different way from your expectation.

.   Any character (may or may not match line terminators)

For space you better use

\s  A whitespace character: [ \t\n\x0B\f\r]

and escape other special characters with a leading \\
