[tteesstt]

<cd>public List infolist()throws Exception{<br> Connection conn = null;<br> Statement stmt = conn.createStatement(); <br> Info in = null;<br> List <Info> list = new ArrayList<Info>();<br> String sql = "select * from YY_INFO";<br> System.out.println(sql);<br> ResultSet rs = stmt.executeQuery(sql);<br> while(rs.next()){<br> in = new Info();<br> in.setId(new Long(rs.getInt("ID")));<br> in.setName(rs.getString("NAME"));<br> in.setAddress(rs.getString("ADDRESS"));<br> in.setAge(new Long(rs.getInt("AGE")));<br> in.setSex(new Long(rs.getInt("SEX")));<br> list.add(in);<br> }<br> return list;<br> }<br>现在写这样的一段代码 要把库里的内容查出来 赋给一个LIST <br>可是现在说是空指针 为啥呢？<br>着急··············</cd>
