2016-2017-2 "Java Programming" X-week study summary# #认识NIOIn Java, input and output, basically the low-level processing in bytes, in fact, most of the byte array in the entire chunk processing, for the dump () method, must handle byte[], must specify the starting point and the number of bytes written out of byte[]. For exampleJava.. There are some decorative classes in the IO suite, such as Datainputstream,dataoutputstream,bufferedreader and BufferedWriter, if you want to tag a chunk of data th

Let's look at how to implement a custom iterator and then begin to understand how the iterator works internally. Let's take a look at an official example:program run output:String "Myiterator::rewind" string (myiterator::valid) "Myiterator::current" string (15) " Myiterator::key "Output key value: Int (0) string (" First_element "string ()" Myiterator::next "string (" Myiterator::valid ") String ("Myiterator::current" string "Myiterator::key" Output k

written to the end or error., use the feof function.For ASCII files, it is possible to infer by =eofFor binary files, you need to use feof to infer whether the end is complete and return 1. otherwise 0.The Ferror function infers if there is an error and returns 0 without errors.File stream PositioningThe Ftell () function returns the current read and write location of the stream, the number of bytes from the beginning of the fileFseek () function changes the current read and write locationThe

This example is relatively well understood, so just give the code.

Brief introduction SPL is all called (Standard PHP library,php Standard library), from the official document, SPL mainly contains the following blocks:InterfaceDataIteratorsAbnormalfunction enhancementArrayobjectSqlfileinfoOne, interface Interfaces provide constraints on classes, and in a well-formed class library there are usually very well designed interface definitions, which include abstractions that are abstract to interfaces and avoid misuse of interfaces. In SPL, the main interface has

the contents of the file cannot be read at all. This is because we use the "rb+" way to open the file, the data is written in binary form, generally unreadable. After the data is written, the position pointer is at the end of the file, and to read the data, the file pointer must be moved to the beginning of the file, which is the role of Rewind (FP).

current position. Seek_set-Set position equals file start. (default value) Seek_end-The set position is the end of the file. Rewind ()--Returns the position of the file pointer, which is where the file pointer moves to the beginning of the file. Syntax structure: Rewind (file pointer) Note: If you open the file in additional ("a" or "A +") mode, any data written to the file will always be appended, regar

corresponding changes occur in the storage structure:"*: This place to think carefully, after the flip operation, in a logical sense, the buffer is indeed reversed, because this time the Channel class (Channel) read the buffer from the position place to continue reading, there will be no read exception. It's not so much."Reverse", it's better to say"Reset", just Here's"Reset"The data in the buffer is not emptied, justresets the limit and position properties of the buffer, and really call the Re

Strictly speaking, the VOD based on HTTP is not really streaming media, English is called "progressive downloading" or "pseudo streaming", why so? Because HTTP lacks streaming media basic flow control, it is very difficult to realize the fast forward of the media playback, fast rewind and pause based on HTTP protocol. So how does a typical Media player use HTTP to do this? As we all know, regardless of the size of the media file, HTTP is only to see

We often say that the design should be crisp and concise, at a glance. Recently we have seen fashionable design trends towards the plane, and today we want to share the design of this kind of page-pricing page design. Many times when you jump from the homepage to the pricing page feel to another site, and the importance of pricing pages is self-evident, want a higher conversion rate may wish to work more on this.

Plainly, the application of the icon is part of the product, is the shape and entrance of the product, in the application design, the application of the image of the icon has become a way to improve product recognition. Users have the habit of classifying the application, imagine if the music folder is a bunch of different color

Sharing is an important part of SoundCloud user culture and music exploration. For now, forwarding may be the most common and effective feature that allows you to share a song with your friends and fans. I like forwarding, but I think SoundCloud will benefit a lot if you pay more attention to private sharing and DMS. More site sharing means more time spent on the site and more exposure to recommended content (Spotify is doing quite well). Also, use

completely different concepts. Let's see why this is. The use of the Internet on the mobile side has become a trend of steady growth. Users are increasingly used to searching and browsing Web pages on their smartphones. To cater to this demand, organizations are paying to hire Web engineers to boost users ' online experience on mobile devices. You may have seen this distinction, such as Amazon on your smartphone and desktop computers. Image: The same Web site, when viewed on diffe
