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

Map map=list.stream().collect(Collectors.toMap(Choice::getName, s->s));

Even serves this purpose for me,

Map map=  list1.stream().collect(()-> new HashMap(), 
            (r,s) -> r.put(s.getString(),s),(r,s) -> r.putAll(s));
