使用流API将列表转换为Java中的哈希映射

Question

我试图使用Java中的流api来转换List<Object> into HashMap<String,Object>

我有一个用户课程

public class User {

    private String name;

    private String mobile;

}

下面的代码创建列表，现在我很困惑将列表传输到hashmap<String, Object>

public class MySample {


    public static void testStream() {
        List<User> oldusers = Arrays.asList(new User("Ankit", "1238982194"), 
                new User("Shweta", "1230007587"),
                new User("Deepika", "1230877825"),
                new User("Arun", "1230903264"),
                new User("Ankit", "1236053822")
                );


    }
