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

    As an alternative to guava one can use kotlin-stdlib

    private Map nameMap(List choices) {
        return CollectionsKt.associateBy(choices, Choice::getName);
    }
