How should I add a whole class in a linked list that also has arguments such as name, password and a boolean to check if it's connected to a server?
The strange thing about this issue is that the User is successfully registered in the User.java, but not in the UserRegistery.java.
public class User {
    private String name = "";
    private String password = "";
    private String email = "";
    private boolean connection;
    public User(String name, String password, boolean connection){
        this.name = name;
        this.password = password;
        this.connection = connection;
        setUserName(name);
        setUserPassword(password);
        setUserConnection(connection);
        System.out.println("Client Created : User ["+format()+"]");
    }
    public void setUserName(String name){
        this.name = name;
    }
    public String getUserName(){
        return name;
    }
    public void setUserPassword(String password){
        this.password = password;
    }
    public String getUserPassword(){
        return password;
    }   
    public void setUserEmail(String email){
        this.email = email;
    }
    public String getUserEmail(){
        return email;
    }
    public void setUserConnection(boolean connection){
        this.connection = connection;
    }
    public boolean getUserConnection(){
        return connection;
    }
    public String format(){
        return String.format("%-5s, %-5s, %s" , getUserName(), 
                getUserPassword(), getUserConnection());
    }
}
public class UserRegistry {
    private LinkedList<User> users;
    private User user;
    private String name = "", password = "";
    private boolean conn = false;
    //Constructor:
    public UserRegistry() { //Setting new students in the Linked List
        users = new LinkedList<User>();
    }
    public void addUser(User aUser) {
        System.out.println("Waiting to "
            + "add user to the server . . . ");
        users.add(aUser);
        System.out.println("Client Creation "
            + ": Confirmed !!! ");
        System.out.println("Client Creation "
            + ": Declined !!! ");
    }
}
This is the output I get:
