Java 5 Application of the original sub-operation class, Java 5 atomic type The java. util. concurrent. atomic package provides operations for basic data types, basic data types in arrays, and basic data types in classes. For more information, see API. The following example briefly introduces the use of the AtomicInteger class: 1 public class AtomicTest { 2 public static void main(String[] args) { 3

Array isArray (0 =>3,2 =>4,3 =>5,5 =>6)In the Json_encode array, the subscript discontinuous array is parsed into a JSON string such as {"0": "3", "2": "4", "3": "5", "5": 6}. Expect {["3", "4", "5", "6"]}. The

When creating a value type instance, we should try to implement it as constant and Atomic. The so-called constant, that is, the object will not be changed after it is created, similarProgramA constant defined in. Once a value type is created, it can be regarded as a constant state. In this way, it is thread-safe. Atomicity refers to some correlated fields in the value type, such as birthdate and age. Age is calculated based on birthdate. if the objec

Go back in the evening to review the original information, return to the codebook there is a "expand a nested Sequence" topic.Task description: The child in the sequence may be a sequence, the child of the subsequence may still be a sequence, and so on, the sequence nesting can reach any depth. You need to loop through a sequence and expand all of its subsequence into a single sequence with only the basic subkeys.For example, the shape is the following sequence a: a = [(123 (78)]" , 45, 69, 10

Otherwise, China may be able to successfully develop an atomic bomb in early 300, but it is clear that the power of the atomic bomb is beyond the control of humans at that time.Hey, I'm afraid it's not a blessing. At that time, all humans may be threatened. The big bang of the Wang Gong factory will make the Ming Dynasty's nuclear technology a torch, and the horse will fall out of service, maybe this expl

Atomic means that the setter/getter function is a primitive operation. If multiple threads call setter at the same time, there will be no execution of setter by another thread before executing all the setter statements, which is equivalent to adding a lock at the beginning and end of the function. Nonatomic does not guarantee the primitive line of setter/getter, so you may get incomplete things.For example, if you use nonatomic to change two member va

When the Linux kernel prints "bug:scheduling while Atomic" and "bad:scheduling from the Idle thread" error,It is usually called in the interrupt handler function that can sleep, such as semaphore,mutex,sleep, such as a dormant function,While the Linux kernel requires interrupt processing, the system is not allowed to dispatch, not allow preemption, wait until the completion of the interrupt processing to do other things.Therefore, to fully consider th

It was only today that C++11 supported atomic operations and also supported the thread class to create threads, which is really getting 6. Before doing the project, the creation thread is the POSIX standard pthread_create function, and the thread synchronization is generally used Pthread_mutex. Today get a new skill, you can use the thread class to create a thread, with the Atomic_flag implementation of spin lock for thread synchronization, do not say

synchronization, two threads may enter the IF statement block at the same time, causing each thread to get a different existingvalue, which is clearly not desirable.

What CentOS is. CentOS is a freely available source code enterprise-class Linux distribution based on Red Hat enterprise-class Linux. Each version of the CentOS will receive seven years of support (via a security update). The new version of the CentOS is released every two years, and each version of the CentOS is updated periodically (about every six months) to support new hardware. In this way, establish a secure, low maintenance, stable, high predictive, high repeatability of the Linux environ
