日期格式错误java.sql.SQLException：列类型无效

当我尝试将日期值插入/更新到我的oracle DB中时,我得到了

java.sql.SQLException: Invalid column type

因为插入或更新之前的日期格式是这种格式

如何正确地将我的日期值插入或更新到Oracle Db以及执行此操作的最佳方法是什么？

我的db插入代码.

private void editSchedule(Schedule schedule)
        Object[] values = { schedule.getStartDate(),schedule.getVacationId() };             
        Connection connection = null;       
        PreparedStatement preparedStatement = null; 
        try {                           
            connection = datacon.getConnection();               
            preparedStatement = prepareStatement(connection,SQL_EDIT,values);         
            preparedStatement.executeUpdate();          

        } catch (Exception e) {
            logger.info("errro "+e.getMessage());
            e.printStackTrace();
        } finally {
            // TODO: handle exception
            close(connection,preparedStatement);
        }

    }

PreparedStaement代码部分

public static PreparedStatement prepareStatement
        (Connection connection,String sql,Object... values)
            throws SQLException
    {
        PreparedStatement preparedStatement = connection.prepareStatement(sql
            );
        setValues(preparedStatement,values);
        return preparedStatement;
    }

    public static void setValues(PreparedStatement preparedStatement,Object... values)
        throws SQLException
    {
        for (int i = 0; i < values.length; i++) {
            preparedStatement.setObject(i + 1,values[i]);
            logger.info("sql  "+Arrays.asList(values));
        }
    }
