Because the program often has a lot of input and output operations on files, it often forms the main part of the program, so the C language provides a lot of input and output functions, they are used for two types of file input and output systems:

Example 1 is an example of using fileinputstream and fileoutputstream. the program can copy the file. It will first read data from the source file to a byte array, and then write data from the byte array to the target file. example 1: filestreamdemo.

C/C ++Input and output stream Summary  When I wrote my c ++ internship assignment two days ago, I suddenly found that I/O was so strange that I/O files were not opened for a long time. Today, I finally decided to find a book, sort it out and share

Notification wait mode The waiting party follows the following guidelines. 1) Gets the lock of the object. 2) If the condition is not satisfied, then the wait () method of the calling object is notified and the condition is still checked. 3)

The socket is one end of two-way communication between two programs running on the network, it can accept the request, also can send the request, can use it to write the data on the network more conveniently. In Java, there is a special socket class

Principle Analysis In the development, "the breakpoint continues to pass" this kind of function is very practical and is common, sounds also has "the force lattice" the feeling. So usually we are interested in studying how this function is achieved?
