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

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
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
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

-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
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
), 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
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
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
, initialize, and unload is OK, the class loading process must begin in this order, and the parsing phase is not necessarily, in order to support runtime binding of the Java language, the parsing action is placed after class initialization. the whole process of class loading Loading
In the load phase, the virtual machine needs to do the following 3 things: 1 to obtain a binary byte stream that defines this class through the fully qualified name of a class. 2) Converts the static storage struc
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

2. 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

Debugging four-wheeled smart vehicles, cricket control systems, two-wheeled upright vehicles, steering gear control, these control systems use PID control, although I already have many ways to improve, however, it is still difficult to break through the limitations of the traditional PID, and the adjustment speed and superadjustment must exist at the same time. To achieve better control effects, we need to know the precise system model
