servlet 编译的问题

Question

以下一个简单的servlet例子 
import   javax.servlet.*; 
import   java.io.*; 
import   javax.servlet.http.*; 
public   class   simplehello   extends   HttpServlet{ 
pulbic   void   doGet(HttpServletRequest   req,HttpServletResponse   resp)   throws   ServletException,IOException 
{     PrintWriter   out=resp.getWriter(); 
out.println("hello   world"); 
out.close(); 
} 
} 
编译时出错如下 
C:\Program   Files\Apache   Software   Foundation\Tomcat   5.0\webapps\ch06\src> javac   si 
mplehello.java 
simplehello.java:5:   <identifier>   expected 
                pulbic   void   doGet(HttpServletRequest   req,HttpServletResponse   resp)   throw 
s   ServletException,IOException 
                              ^ 
simplehello.java:12:   ';'   expected 
} 
^ 
2   errors 请教错在那里！！不胜感激！！

Answer 1

晕，你的public 写的不对 ，写成了pulbic

Answer 2

pulbic 错了       void       doGet(HttpServletRequest       req,HttpServletResponse       resp)       throws       ServletException,IOException  

Answer 3

要学会看异常信息 simplehello.java:5:       <identifier>       expected   

Answer 4

simplehello.java:5:       <identifier>       expected   
                                pulbic       void       doGet(HttpServletRequest       req,HttpServletResponse       resp)       throw   
s       ServletException,IOException   
                                                            ^   
simplehello.java:12:       ';'       expected   
}   
^   
2       errors   
错误原因不是有吗？<identifier> expected  标识符 认为 有错误嘛~
