You can build one of your own. Split the string and concatenate all characters before the index position with the characters of the string you want to insert and with the characters after the index.

eg:

String s = "I stackoverflow";
int index = s.indexOf(" ");
String toInsert = "love ";
String mys = s.substring(0, index) + toInsert + s.substring(index, s.length);
