“Class header expected instead” error

问题

Why do I get this error?

I've been trying to solve it.

package Controller;

import View.ViewGegevens; //Error
import Model.Persoon;
{
private String Voornaam;
private String Tussenvoegsels;
private String Achternaam;
private String Woonplaats;
private int Telefoonnummer;
private String Aardappel;}
public class InvullenData implements ActionListener {

    @Override
    public void actionPerformed(ActionEvent e) {
        // TODO Auto-generated method stub

回答1:

These lines should be within any of class or interface

{
private String Voornaam;
private String Tussenvoegsels;
private String Achternaam;
private String Woonplaats;
private int Telefoonnummer;
private String Aardappel;
}

whatever the variables your declaring must be enclosed within a class because class is a type of Wrapper Mechanism unless they are declared inside the class those will not be available to your class
