Java 8 List into Map

Question

I want to translate a List of objects into a Map using Java 8\'s streams and lambdas.

This is how I would write it in Java 7 and below.

private Map&l         


        

Answer 1

Here's another one in case you don't want to use Collectors.toMap()

Map result =
   choices.stream().collect(HashMap::new, 
                           (m, c) -> m.put(c.getName(), c),
                           (m, u) -> {});
