Templates are an excellent way to save time and avoid code duplication. Without having to enter 20 similar classes, each containing 15 member functions, you can enter a class template (class template) and have the compiler instantiate the 20 specific classes you need (specific class ) and 300 functions. (member functions of class template) are implicitly instantiated only when they are used, so you will get all 300 member functions (members functions) only if each function is actually in use. Fu

. Although the term "fat client" usually represents a common GUI client application, the client is almost obese. This client runs on a Windows platform with a maximum size of 2 GB. After removing the executable address space and the additional space required to introduce various JNI products, the maximum heap size that the application can use is approximately 1.2 GB or 1.3 GB. Unfortunately, some users have to instill large amounts of data into the application so that the space they occupy is of

update to be displayed. This is actually a model of the change-propagation mechanism. The struts framework was first shipped as part of the Apache Jakarta Project, inheriting the features of MVC and making changes and expansions based on the characteristics of Java EE. The struts framework is a good combination of Jsp,java Servlet,java bean,taglib technology. In struts, it is actionservlet that assumes the role of controller in MVC. The Actionserv

We must first remember the characteristics of the three: String string Constants StringBuffer string variable (thread safe) StringBuilder string variable (not thread safe) I. DefinitionThe View API finds that the Charsequence interfaces are implemented by string, StringBuffer, and StringBuilder, although they are all related to strings, but their processing mechanisms are different. String: is a quantity that cannot be changed, that is, when it is created, it cannot be m

How to find a nearby user (merchant, person)The general business logic is that there is a lot of coordinates in the data, knowing a coordinate to find out the other coordinates within a certain range (e.g. within 500 meters).Here are 3 implementation scenarios:(1) MySQL's spatial databaseReference: http://blog.csdn.net/chaiqi/article/details/23099407Starting with MySQL4.1, MySQL has introduced a series of spatial expansions that allow it to have a c

not meet commercial requirements. 5. Scaling Issues Many of the existing blockchain is sufficient to handle simple expansions, but commercially used IT systems should be able to automatically handle a growing number of users or even sudden requests for services. 6. Lack of interoperability There are now a large number of public and private chains, each blockchain design is different, which limits the flow between users. A large number of blockchain p

A String object is called immutable (read-only), and because its value cannot was modified after it had been created. Methods that appear to modify a string object actually return a new string object that contains the Modi Fication.Because strings is immutable, string manipulation routines that perform repeated additions or deletions to what appears t O is a single string can exact a significant performance penalty. stringbuilder class instead of the string class for operations That does m

synchronization, which is a thread-safe implementation. LinkedList uses a circular doubly linked list data structure, which is connected by a series of table items, and a table entry always contains 3 parts, element content, precursor table entries, and back drive table entries.The capacity needs to be expanded when ArrayList exceeds the size of the current array. During the expansion process, a large number of array copy operations are performed, and when the array is copied, the System.arrayc

httpd, Mod_rewrite would only pro Cess The rewrite rules if the request URI is a url-path. This avoids some security issues where particular rules could allow "surprising" pattern expansions (see cve-2011-3368 and cve-2011-4317). To lift the restriction on matching a url-path, the Allowanyuri option can is enabled, and mod_rewrite would apply the rule Set to any request URI string, regardless of whether this string matches the Url-path grammar requir
