JAVA中JTable的问题

这是我的程序，有错，高手帮忙改一下啊：
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class A extends JFrame {
public static void main(String args[]) {
B ab = new B();
}
}
public class B extends JFrame{
public void B()
{
JPanel jp=new JPanel();
add(jp);
JPanel jp1=new JPanel();
JPanel jp2=new JPanel();
JPanel jp3=new JPanel();
JPanel jp4=new JPanel();
JPanel jp5=new JPanel();
JPanel jp6=new JPanel();
JPanel jp7=new JPanel();
JPanel jp8=new JPanel();
JPanel jp9=new JPanel();
JPanel jp0=new JPanel();
jp.add(jp1);
jp.add(jp2);
jp.add(jp3);
jp.add(jp4);
jp.add(jp5);
jp.add(jp6);
jp.add(jp8);
jp.add(jp9);
jp.add(jp0);
setSize(800,800);
setTitle("书的录入");
setVisible(true);

JLabel jb1=new JLabel("书的录入");
jp1.add(jb1);

JLabel jb2=new JLabel("书名");
JPasswordField jt1 = new JPasswordField(10);
jp2.add(jb2);
jp2.add(jt1);

JLabel jb3=new JLabel("价格");
JPasswordField jt2 = new JPasswordField(10);
jp3.add(jb3);
jp3.add(jt2);

JLabel jb4=new JLabel("出版时间");
JPasswordField jt3 = new JPasswordField(10);
jp4.add(jb4);
jp4.add(jt3);

JLabel jb5=new JLabel("入库时间");
JPasswordField jt4 = new JPasswordField(10);
jp5.add(jb5);
jp5.add(jt4);

JLabel jb6=new JLabel("作家");
JPasswordField jt5 = new JPasswordField(10);
jp6.add(jb6);
jp6.add(jt5);

JLabel jb7=new JLabel("入库数");
JPasswordField jt6 = new JPasswordField(10);
jp7.add(jb7);
jp7.add(jt6);

JLabel jb8=new JLabel("类别");
Choice leibie = new Choice();
leibie.add("科幻");
leibie.add("爱情");
leibie.add("恐怖");
leibie.add("侦探");
leibie.add("武侠");
jp8.add(jb8);
jp8.add(leibie);

JButton btn1 = new JButton("增加");
JButton btn2 = new JButton("删除");
jp9.add(btn1);
jp9.add(btn2);

JTable jtable = new JTable(new String[][] {
{"哈","飞","飞","飞","我"," 的","爱情"}，{"哈","飞","飞","飞","我"," 的","爱情"}
},
new String[] { "书名", "价格", "出版时间", "入库时间","作家","入库数","书类别" };
jtable.setRowHeight(25); // 设置行高
jtable.setGridColor(Color.yellow); // 设置边框颜色
JScrollPane jsp = new JScrollPane(jtable);
jtable.setGridColor(Color.yellow);
jsp.setViewportView(jtable);
jp7.add(jtable);
}
}
语法错误我改了，但是不能显示表格，只有其他的内容；还有就是运行的窗口要改边一下大小才能显示东西，要不然就不给显示。高手们，怎么办啊，急啊~~~~~~
答案能运行后马上追50，谢谢

我用的是JCreaor4.0的IDE工具，我运行了后不出现表格，只出现上面的东西，就是没有表格出来，怎么回事啊

Answer 1

在netbeans调试运行过啦，改动如下：
（1）最后一句jp7.add(jtable); 改成jp0.add(jsp);
(2)你这里JTable jtable = new JTable(new String[][] {
{"哈","飞","飞","飞","我"," 的","爱情"}，{"哈","飞","飞","飞","我"," 的","爱情"}
},
new String[] { "书名", "价格", "出版时间", "入库时间","作家","入库数","书类别" };
欠一半括号，我看不太懂，暂且改成JTable jtable = new JTable(new String[][] {
{"哈","飞","飞","飞","我"," 的","爱情"}，{"哈","飞","飞","飞","我"," 的","爱情"}
},
new String[] { "书名", "价格", "出版时间", "入库时间","作家","入库数","书类别" }）;
（3）B ab = new B(); 应该加，ab.setVisible(true);
(4)这点只是建议．你里面大量使用的jPassordField可改用jTextField

Answer 2

jp7.add(jtable);
最后一句改成：jp7.add(jsp);
还有你的程序我大体看了一下，还有语法错误。
JPanel jp=new JPanel();
add(jp);
建议改成：JPanel jp=new JPanel();
getContentPane().add(jp);
最后再加一句:setVisible(true);
应该就可以了.
