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

By realizing that replaceAll() first argument is regex you can make your comparisons much less

For example you can check for possible misspellings of the word career by the following regex

email = email.replaceAll("ca[n|r][e|a][e|a]r", "career"));
