What is the best way to combine two lists into a map? It would be nice to use for (String item: list) , but it will only iterate through one list, and you'd need an explicit iterator for the other list. Or, you could use an explicit iterator for both. Here's an example of the problem, and a solution using an indexed for loop instead: import java.util.*; public class ListsToMap { static public void main(String[] args) { List<String> names = Arrays.asList("apple,orange,pear".split(",")); List<String> things = Arrays.asList("123,456,789".split(",")); Map<String,String> map = new LinkedHashMap<String,String>(); // ordered for (int i=0; i<names.size(); i++) { map.put(names.get(i), things.get(i)); // is there a clearer way? } System.out.println(map); } } Output: {apple=123, orange=456, pear=789} Is there a clearer way? Maybe in the collections API somewhere?
