Is there a way to list the values of an object saved on Hashmap

Question

How to list the values present in the object saved in a hashmap

I'm trying to see if i can get a way to list the values i saved on a object, I'm storing in hashmap, but i don't know if it's possible to retrieve these values

HashMap<String, User> hashUser = new HashMap<String, User>();
hashUser.put(cont, new User(user, password));

hashUser.keySet().stream().forEach((x) -> {
            System.out.println(hashUser.??);
        });

basically my problem is the same as this guy Displaying object values which are stored in a HashMap well, it's kind of solved then

Answer 1

就像@Lutz Horn在评论中写道，您可以使用values()方法来检索哈希图的值。

hashUser.values().forEach(user -> System.out.println("Username: " + user.getUsername() + " Password: "  + user.getPassword()));

Answer 2

hashUser.values() returns a Collection of hashUser values.

Iterator userIterator = hashUser.values().iterator();

with Java 8 userIterator.forEachRemaining(System.out::println);
