The trend of stock prices has always been hard to understand. But on the day of Facebook's IPO, Twitter magically predicted every trend in its stock price change. The social media monitoring platform Datasift monitors FacebookTwitter sentiment on the day of the IPO. That is to say, people publish a lot of comments about Facebook's IPO on Twitter, which may includ

Fitbit upcoming IPO, this is a smart wearable company, the main products for health testing equipment, smart bracelet, smart watch. Let's take a look at some of Fitbit's data. According to its prospectus, Fitbit sold 10.9 million wearable devices in 2014, more than twice times in 2013. As of the first quarter of 2015, Fitbit sold 20.8 million devices from its inception. Its financial position in the past two years was also very good, with a turnover o

(jdk1.8 is metaspace), the permanent band is globally shared, so the static method lock is equivalent to a global lock of the class, locks all the threads that call the method; When synchronized acts on an object instance, it locks all blocks of code that are locked with that object. The realization of synchronizedimplementation as shown;It has multiple queues, and object monitor stores these threads in different containers when multiple threads are accessing an object monitor together

The effect of a biased lock is to completely eliminate the lock, even if the CAS operation is not done.Let's take a look at the state transitions in the synchronization block and out-of-sync blocks in a thread.When multiple threads request an object monitor at the same time, object monitor sets several states to differentiate the requested thread: Contention List: All threads that request a

". When synchronized is applied to the method, the lock is the object instance (this ); when used as a static method, the lock is the class instance corresponding to the object. Because the class data exists in the permanent band, the static method lock is equivalent to a global lock of the class; when synchronized acts on an object instance, the lock is the corresponding code block. In the hotspot In JVM implementation, the lock has a special name: Object monitor.1. thread status and State Conv

, the preference lock mode fails, the lock is revoked back to an unlocked or lightweight lock state. The function of the bias lock is to completely eliminate the lock, even the CAS operation is not done. Let's look at the transition of a thread into the synchronized block and the state of the synchronized block. When multiple threads request an object monitor at the same time, the object monitor sets several states to distinguish the requested thread: Contention list: All threads that request a

of the lock is obtained at the object header, and every time the thread enters the synchronization block, it does not need to be locked, assuming that once another thread acquires the lock, the bias lock mode fails, and the lock is withdrawn back to the unlocked or lightweight lock state. The effect of a bias lock is to completely eliminate the lock. Do not even CAS operations.Take a look at the state transitions that the thread is entering into the synchronization block and out of the synchron

real queue, but a virtual one, because Contentionlist is made up of node and its next pointer logic, and there is no data structure for a queue. Contentionlist is a last-in, first-out (LIFO) queue, each time a new node is added to the team head, the first node through the CAs to change the pointer to the new nodes, while setting the new node next point to the next node, and take action occurs at the end of the team. Obviously, the structure is actually a lock-free queue.Because only the owner t
