inChar+=13;
if(inChar>'z')
inChar-=26;
}
output.append(inChar);
}
}
return output.toString();
})
); //这个;号。
不就：
String translate(String input( {
                              |
                              |
                         这里没有结束吗？：）
String translate(String input( {
后面哪个"("应该是")"吧
还有&是位与，不只搂住是否想要&&
看看这个有没有问题！import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Rot extends HttpServlet
{
    public void doPost(HttpServletRequest req,HttpServletResponse res)
        throws ServletException,IOException{        String text=req.getParameter("text");
        String translation=translate(text);
        res.setContentType("text/html");
        ServletOutputStream out=res.getOutputStream();
        out.println("<html>");
        out.println("<head><title>ROT Translator</title></head>");
        out.println("<body>");
        out.println("<h1>ROT Translator</h1>");
        out.println("<p>Text to translate:");
        out.println("<form action=\"Rot\" method=\"POST\">");
        out.println("<textarea name=\"text\" rows=8 cols=55>");
        out.println(translation);
        out.println("</textarea>");
        out.println("<p><input type=\"test\" rows=8 cols=55>");
        out.println("</form>");
        out.println("</body>");
        out.println("</html>");
}
String translate(String input) {
    StringBuffer output=new StringBuffer();
    if(input !=null){
        for(int i=0;i<input.length();i++){
            char inChar=input.charAt(i);
            if((inChar>='A')&(inChar<='Z')){
                inChar+=13;
                if(inChar>'Z')
                    inChar-=26;
            }
            if((inChar>='a')&(inChar<='z')){
                inChar+=13;
                if(inChar>'z')
                    inChar-=26;
            }
            output.append(inChar);
        }
    }
    return output.toString();
}
}
应该是String translate(String input）吧
