PreparedStatement ps = conn.prepareStatement(sql);
ps.setString(1,name);
ps.setDate(2,new java.sql.Date(birthday.getTime()));
ps.setFloat(3, money);
ps.executeUpdate();
}
}

注：

①一定要将Java的util包中的Date类型转换至Java.sql.Date类型

new java.sql.Date(birthday.getTime())

②sql中的Date类是继承至java.uti.Date类，也就是java.sql.Date类是java.util.Date的子类。
