How do I replace all occurences of a string regardless of case?

java Add comments

By default regexp matching is case sensitive. To make it case insensitive use the CASE_INSENSITIVE flag in your regex. It can be embedded in the regex string using (?i). 


String s = "aBcXYZABCdefAbc";
String replaced = s.replaceAll("(?i)abc", "123");
