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

Based on Collectors documentation it's as simple as:

Map result =
    choices.stream().collect(Collectors.toMap(Choice::getName,
                                              Function.identity()));
