1) dress up the first version of the dish
The following program completes the basic dress types through the console.
Disadvantages:
What if I want to add a "Superman" Dress (wearing underpants?
Changing the person class violates the open-closed principle. How can we optimize it? Write clothing as a subclass to facilitate the extension of clothing subclass.

DB2 online analysis and processing can be described very well. This function is especially suitable for various statistical queries. These queries are difficult to implement with common SQL statements, or are not implemented at all. First, let's start with a simple example to unveil its mystery step by step. Please refer to the following SQL:
Select
Row_number () over (order by salary) as number,
Name as name,
Dept as department,
Salary as salary
From

-- Name department sala
Principle:
Each SQL statement has its execution plan, and the Execution Plan is placed in plan_table. plan_table contains the object_name column, which indicates the object name in the SQL statement. The execution plan is very interested in the table, so if object_type = 'table', object_name is the table_name
Procedure:
1. Create a tmp_table table and store the job name job_id, SQL statement select_ SQL, and table name object_name.
Create table tmp_table (job_idvarchar2 (50), select_ SQL clob, o

2. Create a p stored procedure according to the execution plan

The Arduino pro mini is a micro-control panel based on atmega328 and supports 5 V/3.3v voltages. However, the default voltage is 5 V. How can we make this board support 3.3v voltage.
Preparations
1. If you have never used Arduino, You need to download the IDE first. The installation method is not described here.
2. Prepare two board boards, one of which is our Arduino pro mini target board and the other is the Arduino board used to burn the target board, this article uses the same Arduino pro mi

placed in a separate class and the class is used to wrap the object to be decorated. Therefore, when special behavior is required, the Customer Code can selectively and sequentially use the decoration function to wrap objects at runtime.Advantages of the decoration mode:Remove the decoration function from the class to simplify the original class. Effectively separates the core responsibilities of the class from the decorative functional area. Besides, duplicate decoration logics in related clas

DTX (discontinuous transmission) is a method for optimizing the efficiency of a wireless voice communication system, which shuts down mobile or portable phones at any time without voice input. In a typical 2-way call, each party is slightly less than half the total time, so if the transmitter is only in the presence of voice

Speaking of Oracle analysis functions, it can be described in a very good and powerful sense. This feature is especially useful for a variety of statistical queries that are difficult to implement in normal SQL or are not implemented at all. First, let's start with a simple example, step by step to uncover its mystery, look at the following sql:
