请问这个该如何去写？

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class ShowTimesServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        
     response.setContentType("text/html;charset=GB2312");
     //设置编码，不然中文会变成乱码
     ServletContext context = this.getServletContext();
     PrintWriter out = response.getWriter();
     Integer times =(Integer)context.getAttribute("times");
     if(times==null) {
         times = new Integer(1);
     }else {
         times = new Integer(times.intValue()+1);
     }
     out.println("<html><head><title>");
     out.println("页面访问统计~");
     out.println("</title></head><body>");
     out.println("当前页面被访问过了");
     out.println("<font color=red size=20>"+times+"</font>次");
     //设置属性，将times保存到当前的上下文中
     context.setAttribute("times", times);
     
    }
    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        // TODO Auto-generated method stub
        this.doGet(req, resp);
    }
}
