JAVA concurrent programming J. U. C learning summary, java concurrent programming j. u. cPreface After learning J. U. C for a while, I plan to make a summary. I personally feel that the summary is very important. Otherwise, I always feel that the knowledge is scattered. If you have any mistakes, please correct them and

[JAVA concurrent programming practices] 6. Interrupt and java concurrent programming practices The so-called interrupt operation: it does not actually interrupt a running thread, but only sends an interrupt request, and then the thread interrupts itself at the next appropriate time. Call an interrupt to interrupt the

Java concurrent programming instance (synchronized) and java concurrent programming instance Here, we use a small program to illustrate that the logic is a counter (int I). The main logic function is that if resource I is monitored synchronously, no I value is output, however, if the keyword synchronized is not added,

[Java concurrent programming] 8. Various lock concepts, java concurrent programming Updating... Shared lock (S lock ):If transaction T adds A shared lock to data A, other transactions can only add A shared lock to data A, but cannot apply an exclusive lock until all shared locks are released. Transactions authorized

Java concurrent programming Summary 5 -- ThreadPoolExecutor, java concurrent programming practices I. Introduction to ThreadPoolExecutor In jdk1.8, there are four constructors. To ThreadPoolExecutor (int corePoolSize, int maximumPoolSize, long keepAliveTime, TimeUnit unit, BlockingQueue 1,CorePoolSize: Core thread poo

Concurrent Programming-object combination and concurrent programmingObject combination 1. Design thread-safe classes 1. In the process of designing the thread security class, it should include the following three basic elements: 1) Find all the variables that constitute the object state 2) Find Out immutable conditions for variable Constraints 3) Establish

Preliminary Research on concurrent programming-object sharing and concurrent programmingObject sharing 1. Visibility In the absence of synchronization, the compiler and runtime may make some unexpected adjustments to the execution sequence of the operations. In the absence of a multi-threaded program with sufficient synchronization, to determine the execution seq

IOS Address Book programming, listening for system address book changes, and ios address book Listen for address book changes The client code must be implemented as follows: /* Remove the registration function */-(void) dealloc {ABAddressBookUnregisterExternalChangeCallback

The previously mentioned synchronized mutexes and Reentrantlock are exclusive locks that can only be accessed by one thread at a time. While read-write locks allow multiple read threads to be accessed at the same time, all read threads and all other write threads will block when there is a write thread. Read-write locks maintain a pair of locks, a read lock, and a write lock, which increases concurrency because reading threads are blocked when using exclusive locks, which in contrast does improv

threads that want to acquire the resource need to block waiting.Its core function is to ensure thread synchronization through reentrant lock Reentrantlock. Include put (), offer (), take (), poll (), etc. At the same time, there are two conditions Condition (Notempty, Notfull), the join element is, if the queue is full, you must wait, when the element is taken out, if the queue is empty, you must wait.SummaryConcurrent containers are designed for concurrent
