Without storing the data stream, the random data of n equal probabilities is obtained from the input stream.

There is a large and large input stream, so large that no memory can be stored, and only input once, how to randomly get N records from this input stream. What method can we use to get the random data of n equal probabilities without the need to store the data stream? That's, If m The procedure is as follows: #include using namespace Std;void sample (int n,int* o

Functional Programming (13)-Infinite data stream-infinite stream

In the previous section, we mentioned that the main difference between stream and list is the lazy evaluation feature of stream. We also discussed that when dealing with large array datasets, the stream can move the data elements into memory one at a time and can be processed on an elemental basis. This makes me think of our common data-search reads: A large amou

What happens after I close the IO stream in the Java socket? (for example, to turn off the output stream)

Disclaimer: This post is illustrated with the example of closing the output stream in the socket.To facilitate the explanation, we put dataoutputstream dout = new DataOutputStream (New Bufferedoutputstream (Mysocket.getoutputstream ())); The dout in the socket output stream as the endorsement. Similarly, DIN is the endorsement of the input stream.Actions that can cause dout to be closed are:1, call Dout.clo

Java io stream learning and Java io stream

Java io stream learning and Java io stream I have carefully studied Java I/O streams in recent days. I was planning to watch videos and learn through videos. However, I found that videos are not easy to understand, so I learned the Java io stream through Baidu and api documentation. Io streams can be classified into two types: byte streams and byte streams, and

PHP input Stream php://input use sample (PHP send picture stream to server) _php instance

From the official website, Php://input is a read-only information flow, when the request mode is post, and enctype not equal to "multipart/form-data", you can use Php://input to obtain the original requested data. Look at a simple example. The client is a form, very simple. Copy Code code as follows: Name: Age: Submit the form to the server, and the server uses file_get_contents to get php://input content Copy Code code as follows: $content = file_get_co

"Buffer stream of Io stream for Java"

The Java Buffer stream itself does not have IO functionality, but adds buffering to other streams to improve efficiency, such as loading a wrapper over another stream. When the file or other target frequently read or write or operate inefficient, poor performance. This allows for more efficient reading and writing of information using buffered streams. Because the buffered

Java Stream (stream), file, and IO

Introduction to Java stream, file, and IOThe java.io package contains almost all the required classes for operation input and output. All of these flow classes represent the input source and output destination.The streams in the Java.io package support many formats, such as basic types, objects, localized character sets, and so on.A stream can be understood as a sequence of data. The input

Java IO byte stream and character stream-outputsteam and InputStream

The IO stream in Java is divided into byte stream and character stream, and each stream also divides the input stream and the output stream.Let's start with the input and output streams: the input and output are for program memory, so the input is to write data to the memory

The difference between byte stream and character stream in Java

BYTE streamIn the I/O class library, Java.io.InputStream and java.io.OutputStream represent byte input streams and byte output streams, which are abstract classes that cannot be instantiated, and the smallest unit in the data flow is bytes, so it is called a byte stream.The method of reading data in InputStream is as follows:1, int read ()Function: Reads a byte of data, and returns the read data, and if 1 is returned, it reads to the end of the input stream
