In the case of multithreading, because multiple threads of the same process share the same piece of storage space, there is also a serious problem of access to the conflict at the same time that it brings convenience. The Java language provides specialized mechanisms to resolve such conflicts, effectively avoiding the same data object being interviewed by multiple threads at the same time.

In the same process, multiple threads can be created to share the same block of data space, and the Java language provides a special mechanism to effectively avoid the same data object being accessed by more than one thread at the same time.
Among them, wait and notify is an important part of the Java sy
Having read a book about concurrency, there is a conclusion that using Notifyall is a safer procedure. Take the message queue as an example, assuming that the action put into the element is put, taking the action of the element as the last sentence of Take,put may be
if (count = = 1) {Notempty_cond.notify_all ();}
If you change the Notify_all to notify (), there are cases where concurrency is not sufficient: assuming that the queue is empty for severa
First, thread communication (producer consumer issues):1, Thread communication: a thread to complete its own task, to notify another thread to complete another task.
2, the Classic question : producer and consumer issues.1 There is a thread safety problem: There may be a price disorder, so to lock, and here the product P object is unique, can be used as a lock.
Package sram.thread; Product class product{String name; Name double price; Price}//Pro
Wait (), notify (), Notifyall () are not part of the thread class, but belong to the object base class, which means that each pair has wait (), notify (), Notifyall ()function. Because all have a lock on the image, the lock is the basis of each pair of image, of course, the method of operation lock is the most basic.wait and notify are an important part of the Ja
In Java, you can use the Wait () method and the Notify () method or the Notifyall () method to invoke the object objects to enable communication between threads. Calling the Wait () method in the thread will block notifications waiting for other threads (other threads call the Notify () method or the Notifyall () method), call the Notify () method or the Notifyal
In Java, you can use the Wait () method and the Notify () method or the Notifyall () method to invoke the object objects to enable communication between threads.

First, two concepts: Lock pool and wait pool
Lock pool: Assume that thread a already has a lock on an object (note: Not a Class), while other threads want to invoke some synchronized method (or synchronized block) of the object. Because these threads must obtain the ownership of the lock on the object before entering the object's synchronized method, the lock for that object is currently owned by thread A, so these threads enter the lock pool of the object.
Wait pool: Assuming that
, so the thread that executes the yield () may be executed immediately after it enters the executable state.
Sleep () allows lower-priority threads to be executed, and, of course, can give the same priority and High-priority threads an opportunity to execute; yield () can only give the same priority thread the chance to execute.
When you call Wait (), the thread frees up its "lock flag" so that other synchronized data in the object where the thread is located can be used by another thread.

In the front we will have a lot of questions about synchronization, but in reality, there is a need for collaboration between threads. For example, the most classic producer-consumer model: When the queue is full, the producer needs to wait for the queue to have space to continue to put the goods inside, and during the waiting period, the producer must release the seizure rights to the critical resource (that is, the queue). Because producers do not release the use of critical resources, consume
Communication between Threads uses the Wait/notify method to implement inter-thread communication. Both of these methods are methods of the object class, meaning that all Java objects provide both methods. 1, wait and notify must match synchronized key (or sync Lock) use 2, wait method to release the lock (Wait), notify method does not release the lock (notificat
Java multithreaded design mode wait and notify mechanism summary:
The wait and notify methods must be written in the synchronized method, that is, before calling the wait and notify methods, you need to obtain the object lock;
call the Wait method to release the lock; After the wait method returns, you need to obtain the object lock to continue execu
memory lock is a mutually exclusive operation against the same object, and the static member belongs to the class proprietary, and its memory space is owned by all members of the class, which causes synchronized () to lock the static member, which is equivalent to lock the class, that is, to achieve mutual exclusion among all members of the class. At the same time, only one thread can access an instance of the class. Let's just say that the simple truth is that threads in Java now repel each ot
