Get Name of User From ID - Discord JDA

I get a User from User.fromID(long id)

User u = User.fromID(123456);

I then want to get the name of that user. So I use User.getName()

String name = u.getName();

But then I get an error.

[JDA MainWS-ReadThread] ERROR JDA - One of the EventListeners had an uncaught exception
java.lang.UnsupportedOperationException: This User instance only wraps an ID. Other operations are unsupported

How can I get the name of a User that only wraps an ID?

Any help is appreciated.

You need a JDA instance and use retrieveUserById instead.

Example:

jda.retrieveUserById(userId)
   .map(User::getName)
   .queue(name -> {
   // use name here
       System.out.println("The user has the name " + name);
   });
