Java object serialization learning notes

Document directory Serialization mechanism: Process object stream: Custom serialization process: Fully customized serialization process: Currently, there are many articles on Object serialization on the network, but I found that there are too few articles describing the usage and principles in detail. I have contributed the learning notes I have written after my experience summary and practical use. I hope to do something for the prosperity of the entire Java Community. The serialization p

Java io system details

Java stream processing is divided into two types: byte stream and word throttling. The byte stream processing unit is two bytes of Unicode characters, operating characters, character arrays or strings respectively, while the byte stream processing unit is one byte, operating byte and byte array. In Java, Unicode encoding is used to store characters. The character stream processing class is used to convert external encoded character streams and java Un

Java IO stream learning summary and javaio stream Summary Classes or interfaces related to Java stream operations: Java stream class diagram structure: Concept and function of stream A stream is a set of sequential bytes with a starting point and an ending point. It is a general term or abstraction for data transmission. That is to say, data transmission between two devices is called a stream,The essence of a stream is data transmission. The stream is abstracted into various types based on t

Differences and relationships between JAVA serialization and persistence, java serialization

things, the difference is that persistence is to save it permanently and get it when needed. serialization is concerned with how to change an object to a byte stream. In essence, from a practical perspective, the two have a large degree of mutual coverage. The serialization mechanism is to convert the class value into a general (that is, continuous) byte stream, the process of writing the stream to a disk file or any other streaming target is also known as persistence. Of course, the so-called

A deep understanding of javascript advanced timers

mainstream frameworks is usually used in this way to achieve repeated timing. Function throttling The timer is not only used for timing, but also can be used to relieve the pressure on the browser. Some computing and processing operations in a browser are much more expensive than others. For example, DOM operations require more memory and CPU time. continuous use of too many DOM operations may cause browser suspension, even crash.Function throttling

Summary of parameters related to Linux TCP queue

-delayproduct, bandwidth delay product) is the bandwidth of the network and the product of the RTT (roundtrip time), which means the maximum amount of data that is unacknowledged at any moment in transit. RTT can be easily obtained using the ping command. To achieve maximum throughput, the Recvbuffer setting should be greater than the BDP, which is recvbuffer >= bandwidth * RTT. Assuming that the bandwidth is 100mbps,rtt is 100ms, then the BDP is calculated as follows:BDP = 100Mbps * 100ms = (10

Summary of parameters related to Linux TCP queue

after 2.6.17, the actual size of Recvbuffer will automatically float between the minimum and maximum value, in order to find the balance point of performance and resources, so it is not recommended to set Recvbuffer manually to fixed value in most cases.When Net.ipv4.tcp_moderate_rcvbuf is set to 1 o'clock, the automatic throttling mechanism takes effect, and the recvbuffer of each TCP connection is specified by the following 3-tuple array:Net.ipv4.t

JavaScript Advanced tips Sharing

), then it is executed immediately. Otherwise, this function will be executed after the transaction of the queue has been processed. Therefore, using settimeout or setinterval is not an accurate control time. And one thing to note is that using settimeout to simulate sEtinterval can accurately control the minimum execution time interval. nbsp; nbsp; 6, use timer fixed time to execute method. If a method is executed for a long time, which may cause the browser to not respond for a short period, y

Streams in Java (concepts and examples)

first of all, what the stream is. The flow is an abstract concept, is the abstraction of the input, in the Java program, the data input/output operation is in the "Flow" way. Devices can be files, networks, memory, and so on. Flow has directionality, as for the input stream or output stream is a relative concept, generally with the program as a reference, if the flow of data to the device, we become the output stream, and vice versa we call the input stream. The flow can be imagined as a "flo

Why TCP transmission is reliable

TCP provides a reliable, connection-oriented, byte-throttling service. Connection-oriented: means that two applications that use TCP (typically a client and a server) must establish a TCP connection before exchanging data with each other. In a TCP connection, only two parties communicate with each other. Broadcast and multicast cannot be used for TCP. TCP provides reliability in the following ways: 1. The application data is segmented into a bloc

code into the queue after a certain time has passed. (1) Repetitive timer There are two problems: 1. Some intervals are skipped; 2. The interval between code execution for multiple timers may be smaller than expected. To avoid the two disadvantages of repeating timers for setinterval (), you can use chained settimeout () calls. (2) Yielding processes JavaScript that runs in the browser is assigned a certain amount of resources, one of which is the restriction of long-running scripts, and does n

Structured data processing implemented in Python Now the question is: would it be possible to use Python to achieve this structured data processing as easily? That is, the need to implement the following functions: To access the data segment by variable name, do not need to manually calculate the offset to handle the bit-level data section can easily form a serial c

Java I/O Streams

Byte Streams The program uses byte streams to input and output bytes (8-bit), all of which are inherited from InputStream and OutputStream. The Java platform defines a lot of bytes for us, and we focus on the file byte stream, so we can better demonstrate that the other byte streams are not as different as they used to be, except for the constructors. We have a case to start exploring the word throttling bar. Import Java.io.FileInputStream; Import Ja

Analysis of java.io input-output stream filter stream buffer stream and data stream _java

java.io uses design patterns such as adapter pattern decoration mode to solve the socket and input-output problems of character streams. A byte stream can only be processed at a time, in order to more easily manipulate the data, it adds a socket flow. Problem Introduction: Why is the buffer stream more efficient than ordinary file-byte throttling? An operation without buffering, which writes a byte every time a byte is read. Because disk-related

Origins story of 12 programming languages

"elegant", "clear", "simple". The Python Developer's philosophy is "in one way, it's best to have only one way to do something." When designing the Python language, Python developers tend to reject the fancy syntax when faced with a variety of choices, and choose a syntax that is unambiguous or rarely ambiguous. These guidelines are called "Python maxims."9, the origin of GoGo, also known as Golang, is a programming language developed by Google that is statically strong-typed, compiled, and hai
