System.out.println(str);
public PERMISSION GETBY(String str) throws SQLException
JDBCconnection db = new JDBCconnection();
db.creatConnection();
ResultSet rs = db.excuteQuery("select * from RECOMMENDED where " + str);
PERMISSION permission = null;
while (rs.next())
permission = new PERMISSION();
permission.setDAOCHU(rs.getString("DAOCHU"));
permission.setSHANCHU(rs.getString("SHANCHU"));
permission.setTIME(rs.getString("TIME"));
permission.setXIUGAI(rs.getString("XIUGAI"));


db.closeConnection();
return permission;




在 public PERMISSION GETBY(String str) throws SQLException 这一行出现了“非法的表达式开始”，求Java大神给解释一些，谢谢
只要能回答的将加100财富值

参考技术A 在那行前面加个花括号：
