Java 具有输出的动态web服务器servlet问题

我的web服务器有问题。我需要引入参数，在引入参数后，在课堂上的计算中使用该值。在计算之后，我需要在按下ok按钮后显示该值

package CalculatorOnline;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet("/TestCalc")
public class TestCalc extends HttpServlet {
    private static final long serialVersionUID = 1L;

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        int  Prescale = Integer.parseInt(request.getParameter("prescaler"));
        int TimerMO = Integer.parseInt(request.getParameter("timermode"));
        long TTTicks = Integer.parseInt(request.getParameter("ttticks"));
        double  Freq = Integer.parseInt(request.getParameter("freq"));

        System.out.println("Frecventa:"+ Freq);
        System.out.println("Prescaler:"+ Prescale);
        System.out.println("TimerMod:"+ TimerMO);
        System.out.println("TotalTimerTicks"+ TTTicks);
        TestLabclass temp = new TestLabclass();
        temp.setFreq(Freq);
        temp.setPrescaler(Prescale);
        temp.setTTTicks(TTTicks);

        PrintWriter out = response.getWriter();
        double TimeU2 = temp.getTimeU();
        double RealT = temp.getRealT();

        out.println("Timpului pina la umplere : "+ TimeU2);
        out.println("Real time per tick : "+ RealT);
    }
}
