你好，两个jsp文件，test02.jsp,test03.jsp.代码如下：

<%@ page contentType="text/htmlcharset=gb2312" %>

String num = (String)request.getParameter("num")

try{

int n = Integer.parseInt(num)

if(n%2==0)

request.setAttribute("type","偶数"槐裤祥)

else

request.setAttribute("type","奇纯谨数")

request.getRequestDispatcher("test03.jsp").forward(request,response)

}catch(Exception e){

e.printStackTrace()

}

<%@ page contentType="text/htmlcharset=gb2312" %>

<% String type = (String)request.getAttribute("type")%>

<html>

<body>

请输入一个数字：<input type="text" name="num" />

</form>

${type }

</body>

</html>
