import java.awt.*;
import javax.swing.*;
//import java.awt.event.*;

public class Ticketing extends JFrame
{
//declare class varibles
//jp,jl,jb,jtf indicate the component typs
//JPanle,JLabel,JButton,JTextField respectively;
private JPanel jpTitle,jpSeat,jpInfo,jpRpack,jpSum,jpTop,jpBottom;

private JTextField jtf1;

public static void main(String[] args)
{
Ticketing t=new Ticketing();
t.setVisible(true);
}//end of main

/* constructor */
public Ticketing()
{
setSize(600,800);
setTitle("OTS");
getContentPane().setLayout(new BorderLayout(4,1));

/*****jpTop to contain jpTitle,jpREs

这里：

jlPrice.add(jlPrice);

怎么能自己添加自己呢？？？！！！！！
还有，你的JButtom在哪里定义的？？？

给你凑乎的改了一下:

自己看吧:
