public void lihatDataDiri ()

(
System.out.println ("\ n" + this.nama + "which has a hobby:" + this.hobi);

In userInterface.java file
import java.io. *;

public class userInterface
(
public static void main (String args [])
(
a user user = new object ();// creation of user classes
a.setNamadanHobi ("Stephen", "read ");// give a name and a hobby in objects
System.out.println ("\ n \ tWelcome");
