Dynamic currently, the entire development community is Aspect oriented programing, and there are a number of excellent frameworks that support AOP,--Spring, JAC, Jboss AOP, and so on. AOP seems to have become a fad. Java beginners can not help but to make sense, OOP has not learned, but also to AOP. This article is not to elaborate on the theory of what AOP, why AOP.

operation to be ready from time to time, which requires the user process to continually inquire, thereby introducing unnecessary waste of CPU resources. Asynchronous blocking Io (Java NIO): This means that after the application initiates an IO operation, do not wait for kernel IO operations to complete, and so the kernel completes the IO operation will notify the application, this is actually synchronous and asynchronous the most critical difference, synchronization must wait or actively ask IO

As a kind of structured programming, functional programming is being paid more and more attention. Project is not just object-oriented programming, more people try to start using functional programming to solve problems encountered in software engineering. What is functional programming. A detailed definition is given in Wikipedia, functional programming (English: Functional programming) or function programming, also known as functional programing, is

, although some considerations for usage need to be noted. For more information on these considerations, see the "Multi-threading with Core Data" section of Core Data programing guide. Core Foundation (Central framework) Core Foundation is thread-safe enough, and if your program is aware of it, you should not encounter any problem with threading competition. Typically, it's thread-safe, such as when you query, reference (retain), release, and pass imm

values. int hash = hash (k); int i = indexfor (hash, table.length); This two consecutive steps is the HashMap of the most cattle place! After the study I was ashamed, where the hash is through the key of the object Hashcode hash, and then through the indexfor to get the index value in object table. Table??? Don't be surprised, in fact HashMap also God not where to go, it is to use a table to put. The best thing is to use hash to return the index correctly. One of the hash algorithm, I and JD

Software is dominating the world. And the core of the software is the algorithm. Algorithm millions, and what algorithms belong to the "crown of Pearls" it? Marcos Otero gave his opinion . What is an algorithm? In layman's terms, an algorithm is a well-defined calculation process that can have values or a set of values as input and produce some values or a set of values as output. So the algorithm is a series of calculation steps that convert

like a string of pearls. Its spirit and intention should always run through. In a program, neither too much nor too little content should be involved. There should be neither unnecessary loop structures nor redundant variables; there should be no structural or overly rigid structures.A program should be run in a whole way no matter how complicated it is. Procedures should be guided by their internal logic, rather than the external form.If a program f
