{{{ The developer should use navigiable map so that he can easily find the group of people in the given range by using various methods of navigiable map for e.g . map.headMap(valueAge); // less than value age map will return map.subMap(valeAge1,valueAge2); //between range the map will return map.tailMap(valueAge);// greater than value age map will return } } - Anonymous October 10, 2013 | Flag Reply

What about store group as string eg: "0-25", which ca be used as key in a HashMap. By this way we can retrieve element in constant time :)

HashMap. Each range should have unique hash. Very simple question.
