[FIXED] Replace capital letter with underscore + lowercase letter in Java?

Issue

Is there a way to use RegEx in Java to replace all capital letters with an underscore and the same letter only lowercase?

Example: getSpecialString -> get_special_string

Solution

Just try with:

"getSpecialString".replaceAll("([A-Z])", "_$1").toLowerCase();
