Question

I have a code like this

Map<String, List> searchMap = new HashMap<String, List>();
for(int i=0; i<something.size(); i++){
 List<String> list = new ArrayList<String>();
 list = getResult(...);
 ...
 searchMap.put(differentkey, list);
}

Each time I am creating new List in loop. How to avoid creating new list in loop.

Answer 1

Simply don’t create the List at all since it is not even used in the code you have shown.

List<String> list = getResult(...);
