String literal is not properly closed by a double-quote

运行时时候就出现这个错误

哪位帮我看看啊

解决方案 »

  1.   

    String literal is not properly closed by a double-quote 是说字符串缺少一个"
    out.ptintln("你共用了 "+c+"次); 这里是少了一个吧！！！
      

  2.   

    我帮你修改了代码了 错误不少啊
    你复制我给你修改后的代码吧<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>
    <html>
    <body>
    <% 
    int nub=0;
    int a=0;
    int c=0;
    if(request.getParameter("number")!=null&&request.getParameter("number")!=" ")
    {
      nub=Integer.parseInt(request.getParameter("number"));
      c=((Integer)session.getAttribute("count")).intValue();
      a=((Integer)session.getAttribute("num")).intValue();
      if(nub>a)
      {
      c++;
      String s=String.valueOf(c);
      session.setAttribute("count",s);
      response.sendRedirect("1.html");
      }  
      if(nub==a)
      {
        
      out.println("恭喜你猜对了，答案是"+a);
      out.println("你共用了 "+c+"次");
      }
      else
      {
      c++;
      String s=String.valueOf(c);
      session.setAttribute("count",s);
      response.sendRedirect("2.html");
      }  
    }   
    %>
    </body>
    </html>
      

  3.   

    不行啊。现在又出现这些
    org.apache.jasper.JasperException: Exception in JSP: /check.jsp:118: if(request.getParameter("number")!=null&&request.getParameter("number")!=" ")
    9: {
    10:   nub=Integer.parseInt(request.getParameter("number"));
    11:   c=((Integer)session.getAttribute("count")).intValue();
    12:   a=((Integer)session.getAttribute("num")).intValue();
    13:   if(nub>a)
    14:   {
      

  4.   

    request.getParameter("number")!=" "
    比较字符串不要用==
    改成"".equals(request.getParameter("number").trim())) 你这个错应该是转换数字出错了，应该是接受的参数不是int型的，所以转换成int出错了
      

  5.   


    session.getAttribute("count")
    session.getAttribute("num")
    将这两个做一下判断之后再做类型转换吧
