This chapter begins with the introduction of another important system in Java IO, the character stream. The byte is to the computer to see, the character characters is the person to be able to realize, can imagine the character stream importance. The root of the character stream system is the abstraction of the parent
Speed PDF Reader, is a small series has been used in one of the PDF reader, from the Speed PDF Reader Open PDF file, basically most of the text can be copied, very convenient. If you don't know how to copy the Speed PDF reader, look at the following tutorial!

After that, CTRL + a copies the contents of the text and then paste it into Word OK.
In some cases, the PDF file is encrypted, you cannot view the file in text mode, you can check file security to see if it is not allowed, sele
characteristics of UDP data transmission, its unreliability also brings us trouble in the development process, for such problems, the following solutions are proposed:The server and client can establish a set of their own calibration scheme (many scenarios such as XML, checksum, etc.), if the data packet loss caused by incomplete data, the replacement of the form to complete, of course, this scheme is similar to the TCP handshake connection.In the development process there are a lot of details,

Set three mutex semaphores:
Rwmutex is used to access Shared data that is mutually exclusive to other readers/writers.
Rmutex is used to access the reader counter readcount that is mutually exclusive to the reader.
Wmutex is used by the writer to wait for the reader to exit.

MF RC522 RF Card Reader based on ARM and linux, mfrc522
Abstract: In this design, the embedded technology of ARM and linux is combined with RFID technology, which is of special significance for realizing low power consumption, portable and networking of mobile payment terminals. The first is to use the MF RC522 chip to design and create a reader to read and write the Mifare card. The second is to use the S
The read () method of the InputStream class is to take a byte out of the stream, his function prototype is int read () , and the Read () method of the reader class is to remove a character (a char) from the stream. His function prototype is also int read (); .We all know that Java is using the Unicode character set, in Java characters and strings are used UTF-16BE encoding, that is, a character of two bytes, in memory high in low-byte, this is the o
design of reader and writer character streams:FileReader is a subclass of InputStreamReader, and InputStreamReader is a subclass of reader; FileWriter is a subclass of OutputStreamWriter, And OutputStreamWriter is the subclass of writer. The difference between a character stream and a byte stream is that the character stream operation object is an array of characters and characters, and the byte-stream oper
