I need to augment some string like it's done by logback/famous loggers or property accessors. 

String str= "I can {0} give {1} back your horses or restore your {2} to life.";
String[] got=new String[]{"not","you","dead"};

Are they any utility functions provided by any library that can convert str to replace {i} with indices in array?

Its most probably a duplicate and please refer me to some similar question.
