of the instance they are called, and Sleep () is available everywhere. The biggest difference between wait () and sleep () is that sleep () does not release object locks, and wait () is freed, so it is better to consider the wait () method in terms of efficiency.6. The basic principle of synchronous design: the smaller the code in the synchronization block (synchronized) the better!Do not write blocking code in the synchronization block (for example, Inputstream.read ())!Do not invoke methods o

Java 8 enhanced tool class Arrays notes, java8arrays Make notes at willArrays tool categories are divided into two categories: Single-thread and multi-threadAll of the following statements with a subscript range are headers without tails.Single thread:1. binarySearch: The subscript of the key in the search array: binarySearch binary search. The array must be ordered and exist in this array. Otherwise, a negative subscript is returned. Arrays. binarySe

, the number of bytes transferred is less than the number of bytes requested .Also note that in the Soketchannel implementation, Socketchannel only transmits the data that is prepared at this point (which may be less than count bytes). Therefore, Socketchannel may not transfer all of the requested data (count bytes) to FileChannel.(2) TransferTo ():The TransferTo () method transfers data from the FileChannel to other channel . The following is a simple example:1 Randomaccessfile FromFile =NewRan

accept () method is blocked until a new connection arrives.Typically, you will not just listen to one connection, but call the Accept () method in the while loop. As in the following example:1 while (true) {2 Socketchannel Socketchannel =3 serversocketchannel.accept (); 4 5 // Do something with Socketchannel ... 6 }Of course, you can also use exit criteria other than true in the while loop.3. Non-blocking modeServersocketchannel can be set to non-blocking mode. In nonblockin

connection is established. In order to determine whether a connection is established, you can call the Finishconnect () method. Like this:Socketchannel.configureblocking (false); Socketchannel.connect (new inetsocketaddress (" Http://jenkov.com ", ()); while (! Socketchannel.finishconnect ()) { //Wait, or do something else ...}(2) write ()In non-blocking mode, the write () method may return if nothing has been written. So you need to call write () in the loop. There are already examples, an

[Django] data export excel enhanced version (very powerful !), Django data export Not to mention, the principle is to use xlwt to export excel files. The so-called forced version refers to the implementation of selecting certain conditions on the webpage to export the corresponding data. I have published such articles in my blog post before, but I only want to export data. This time, I thought about it and added the online search to finally find out h

C # web crawler-multi-thread processing enhanced edition, The last time I made a web crawler for my company's sister, it was not very delicate. I used it in this company project. So I made some changes and added the web site image collection and downloading functions, download images from the web page of the thread processing interface. Let's talk about the train of thought: the Prime Minister obtains all the content of the initial website, collects i

Practical notes for learning using LinQ (2) C # enhanced features, C # added many language features for the support of LINQ: Implicit local variables Object initializer Lambda expressions Extension Method Anonymous type Understanding these new features is an important prerequisite for a comprehensive understanding of LINQ, so do not ignore them. (1) Implicit local variables The highlight of processData is {get; set;}, which is a new feature.

It is necessary to clarify a general misunderstanding before continuing the explanation. Because Java is used to create web pages, Beginners sometimes confuse Java with Hypertext Markup Language (HTML), or think that Java is only a few improvements to HTML. Fortunately, this is just a misunderstanding. In essence, HT
