int age = request.getParameter("Age");

总是这句报错。

 <%
    request.setCharacterEncoding("utf-8");
    String sno = request.getParameter("Sno");
    String sname = request.getParameter("Sname");
    int age = request.getParameter("Age");
    String sex = request.getParameter("Sex");
    String sdept = request.getParameter("Sdept");   
    Student s = new Student(sno,sname,age,sex,sdept);
    StudentDaoImpl sdi=new StudentDaoImpl();
        if(sdi.deleteStudent(s)>0){
            //response.sendRedirect("userlist.jsp");
            out.print("<script type='text/javascript'>alert('成功删除此行记录！');</script>");
        }
        else
            out.println("<script type='text/javascript'>alert('没有此用户');location.replace('userlist.jsp');</script>");

 %>

建表和初始化都是整形，为什么会出现这种错误？

 

 create table App.student(sno varchar(10),
                     sname varchar(40),
                     sex varchar(2),
                     age int,
                     sdept varchar(50),
                     primary key(sno));

 public Student(String sno, String sname, int age,String sex,  String sdept) {
        super();
        this.sno = sno;
        this.sname = sname;
        this.sex = sex;
        this.age = age;
        this.sdept = sdept;
    }
