JSP遍历及定位MYSQL数据库的程序出错了

昨天刚做好连接数据库的例子，今天继续做遍历与定位的方法，错误很多，请前辈们帮忙~~代码：

int rowcount;
int introw;
int row;
java.lang.String.strrow;
strrow=request.getParameter("row");
if(strrow==null){
introw=1;
}else{
introw=java.lang.Integer.parseInt(strrow);
if(introw<1)introw=1;
}
Statement stmt=conn.creatStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
ResultSet rs=stmt.executeQuery("select *from information");
re.last();
rowcount=rs.getRow();
if(introw>rowcount)
introw=rowcount;
if(rowcount>0)
{
rs.absolute(introw);
}
%>
<!--显示数据-->
