patterns (principles).Dry–don ' t Repeat yourselfOur first object-oriented design principle is: DRY, from the name you can see that DRY (don ' t repeat yourself) means not to write duplicate code, but to abstract it into reusable blocks of code. If you have two or more blocks of the same code, consider abstracting them into a single method, or you use hard-coded values several times, set them as public constants. The advantages of this object-oriented design principle are ease of maintenance. I

Status chart statechart diagram shows the possible state of the object and the transfer caused by the state change.The model example shows how to create an online logon system for a bank. The logon process includes entering a valid password and personal account, and then submitting it to the system for verification. The logon system can be divided into four non-overlapping states: Getting SSN, getting pin, validating, a

serial number (TSN) and the stream serial number (SSN) are two different serial numbers. The TSN ensures the reliability of the entire association, while the SSN ensures the order of the entire stream. In this way, during transmission, data reliability and orderliness are separated independently.

then submitting it to the system for verification. The logon system can be divided into four non-overlapping states: Getting SSN, Getting PIN, Validating, and Rejecting. Each status has a complete set of transfer transitions to determine the sequence of States. The status is represented by a rounded rectangle. The transfer is represented by a line with arrows. The event or condition that triggers the transfer is written next to the arrow. There are

avoid rule checks. Setting Toggle Rate assignments for a single-ended pin removes the gap between this pin and the differential signal. The Output Enable Group assignment setting can meet the voltage reference signal interval requirements. C. Reduce the simultaneous switch noise (SSN ). Method:1). It is better to separate the simultaneously flipped pins and put them in two different banks.2) high-speed pins. Stay away from VCC And GND and keep static

-defined data types. The system stored procedure sp_addtype can be used to create user-defined data types. The syntax format is as follows:Sp_addtype {type}, [, system_data_bype] [, 'null _ type']Type is the name of the user-defined data type. System_data_type is the data type provided by the system, such as Decimal, Int, and Char. Null_type indicates how the data type handles NULL values. It must be enclosed by single quotation marks, such as 'null', 'not null', or 'nonull '.Example:Use custExe

Netstat The netstat command is a very useful tool for monitoring TCP/IP networks. It displays the route table, the actual network connection, and the status information of each network interface device, after netstat is executed on my computer, the output result is: Active Internet connections (W/O servers)PROTO Recv-Q send-Q local address foreign address StateTCP 0 2 210.34.6.89: Telnet 210.34.6.96: 2873 establishedTCP 296 0 210.34.6.89: 1165 210.34.6.84: NetBIOS-SSNEstablishedTCP 0 0 localhost

that the session does not exist because the session has expired, then we can easily determine whether the session has expired. The method is as follows: If (request. getsession (false) = NULL) System. Out. println ("session has been invalidated! "); Else System. Out. println ("session is active! "); You may have noticed that there is an "Approximate" word above, that is, there are special situations.In this special case, when the first request has not yet created a session, the returned value
