構造函數Object（String）未定義;方法setLayout對於類型eventHandling是未定義的？

Question

import java.awt.*;  
import javax.swing.JFrame; 
import javax.swing.JTextField; 
import javax.swing.JPasswordField; 
import javax.swing.JOptionPane;     


    public class EventHandling { 

private JTextField paco; 
private JTextField paco2; 
private JTextField paco3; 
private JPasswordField passwordField; 

    public EventHandling(String s, String set) { 

      super("title");        

      setLayout(new FlowLayout()); 


    } 

} 

所以我得到這個錯誤在「超（」標題「）;」 - 構造函數Object（String）未定義, 然後對於「setLayout（new FlowLayout（））;」 - 的方法的setLayout（的FlowLayout）是未定義的類型EventHandling

Answer 1

public class EventHandling extends JFrame {
