哪里错了

Question

public static void mian(String args[])
                   ~~~~
                   main

Answer 1

这个不用调了吧，主函数的写法是main不是mian

Answer 2

怎么还AWT呢，怎么不用swing？

Answer 3

给frame加个WindowAdapter就能退出了
f.addWindowListener(new WindowAdapter()
                {
                      public void windowClosing(WindowEvent e)
                            {
                                   System.exit(0);
                            }
                });
