ReplaceAll() -> replace() for non regex strings

Use String.replace() instead of String.replaceAll() when replaceAll() does not use a regex

replace() does not need extra compilation / performance overhead when a non-regex string is used. Thus changing replaceAll() to replace() can remove the associated performance overhead.
