Convert a linked list toUpper, and toLower?

Hey does java have anything built into the api that can convert a linked list  "toUpper" or/and  "toLower"? if so what is it? It would also be nice to see the non importing way to do it also if its not to hard. Thanks

yes but not in list but in String

you need to travers the list and update each element
for e.g.,

for( int i = 0; i < list.size(); i++ ){
 list.set( i, list.get( i ).toUpperCase() ) ;

Thanks I thought it might be something like that, but wasnt sure if the linked list class had its own method built into the api or not. Thanks a lot for help
