replace all + with -

Question

I am trying to replace a + character into a hyphen I have in my string.

String str = \"word+word\";
str.replaceAll(\'+ \', \'-\');
         


        

Answer 1

If you are not sure about the escape sequence you need to use,

You could simply do this.

str = str.replaceAll(Pattern.quote("+"), "-");

This will automatically escape the regex predefined tokens to match in a literal way
