lock vector

First, Introduction Before we explain these lock concepts, we need to be clear that these locks are not equivalent to Reentratlock locks in the Java API, which are conceptually, the locking mechanisms that are created in JDK1.6 to optimize the

ArrayList is an array-based implementation, with no capacity constraints.When you delete an element, it does not reduce the size of the array, and you can call ArrayList's trimetosize () to reduce the capacity of the

Summary This series is based on the gold course, in order to better study, do a series of records. This article mainly introduces: 1. The idea and method of lock optimization 2. Lock optimization within a virtual machine 3. Case of an error using

Thread Safety and lock optimization Thread Safety Thread safety in the Java language Not variable Relative Thread safety Absolute thread Safety Thread compatible

1. PrefaceThe previous article recorded the relationship between Java's memory model and thread, which has been addressed by the memory model to the problem of thread safety. This article will be a specific description of thread safety, the

With the development of the Internet, more and more Internet enterprises are confronted with the concurrency security problems caused by the expansion of user volume. This paper mainly introduces several kinds of locking mechanisms common in Java

Linear tables, linked lists, and hash tables are common data structures. During Java Development, JDK provides a series of corresponding classes for us to implement basic data structures. These classes are in the Java. util package. This article

With the development of Internet, more and more Internet enterprises are confronted with the problem of concurrent security caused by the expansion of user volume. This paper mainly introduces several kinds of lock mechanisms which are common in

Thread Safety When multiple threads access an object, the This object is thread-safe if it does not take into account the scheduling and alternating execution of these threads in the context of execution, the need for additional synchronization, or

Recently learned some about three-dimensional space rotation related knowledge, to comb the memo.The rotation of the three-dimensional space (3D Rotation) is a very magical thing: if a rigid body in three-dimensional space for any rotation, as long
