bean集合拆分成多个list

Question

现在有个bean的list，需要拆成多个成员的list，怎么写比较好？

public class User {
    private String name;
    private String age;
    //..getter,settter省略
}
List<User> data = ...
List<String> name = data里的所有name
List<String> age = ...

Answer 1

List<String> name = data.stream().map(User::getName).collect(Collectors.toList());
List<String> age = data.stream().map(User::getAge).collect(Collectors.toList());

Answer 2

Map<String,User>这种应该可以满足你，key用name，value直接放bean
