1、用convert()转化函数：

String sqlst = "select convert(varchar(10),bookDate,126) as convertBookDate from roomBook where bookDate between '2007-4-10' and '2007-4-25'";

System.out.println(rs.getString("convertBookDate"));

2、利用SimpleDateFormat类：

先要输入两个java包：

import java.util.Date;
import java.text.SimpleDateFormat;

然后：

定义日期格式：SimpleDateFormat sdf = new SimpleDateFormat(yy-MM-dd);

sql语句为：String sqlStr = "select bookDate from roomBook where bookDate between '2007-4-10' and '2007-4-25'";

输出：

System.out.println(df.format(rs.getDate("bookDate")));
