public class Test {public static void main (string[] args) {User U = new User ("FFF"); Test.setusers (U); System.out.println (U.getname ());} public static void Setusers (User u) {u = null;}} public class User {private string name;public User (String name) {this.name = name;} Public String GetName () {return name;} public void SetName (String name) {this.name = name;}}

It's so weird, it turned out to be FFF.
