The first is the simple factory model.In a word, a factory class is used to encapsulate the new factory and return a reference to the newly created object. If the method is static, it is called a static factory. This is generally a common practice, especially in some Java tool classes. Its advantages and disadvantages

First, Factory mode (Factory): by letting subclasses decide what the object is created to achieve the purpose of encapsulating the object creation process, the factory method defers instantiation of the class to the subclass(1) involved roles: abstract products, specific products, abstract creators, concrete creators. (2) Example:Abstract Product class1 Public A

. Therefore, whether static classes are used or not depends on the actual situation. Ii. How does the log producer pass in the parameter or? Iii. How to Write logs, synchronous or asynchronous? 4. Log File storage location and file size control. 5. Expansion problems. I am going to talk about the second, third, fourth, and fifth points in one piece. In fact, there are two types of logs: Fixed logs, such as system logs or internal framework logs, and user logs, such as in Web appli

According to the order list, the HP rx2660 minicomputers in various cities are configured with 4 146 gb sas 10 k 2.5 inch hard disks. When the operating system is installed, two disks are automatically made into RAID 1, the principle is to prioritize hard disks with a large slot number (from left to right, such as 1, 2, 3, 4, 5, 6, 7, and 8 ). Check whether the host's built-in hard drive has been made into RAID 1: From the above output information,

Someone in the Forum asked if the SQL Server account can be case-sensitive. In fact, it is okay, but there are prerequisites. Many people think that only passwords of SQL Server are case-sensitive, while SQL login accounts are case-insensitive. The default SQL Server login account is case insensitive, but if you installIf the server sorting rule is case-sensitive, the login account of SQL Server will also be case-sensitive (for SA accounts, you can create SA, SA, and SA ). For example, my

In object-oriented programming, the most common approach is to create an object instance with a new operator, which is used to construct an object instance. In some cases, however, the new operator directly generates the object, causing some problems. For example, the creation of many types of objects requires a series of steps: You may need to calculate or get the initial settings of the object; Select which child object instance to generate; Or, you must generate some accessibility objects bef
