First, overview:This is the first to read the original English professional books, in general, because they have some foundation, reading is not very laborious.The first half of the main is to introduce the Java related syntax, just by this opportunity to consolidate the ability of their code, basically the bookThe code is played again, the front part is mainly used by the notepad++ to write, notepad++ also

The second week of object-oriented programming (Java) Learning Summary The direct study sister learns the younger brothers good! The amount ... Don't ask me why I put my sister in front, I do not know! I'm just one of your amiable seniors. Do not ask why the second week study summary instead of the first week, because the first week seniors are eating watermelon blowing air conditioning. All right, gossip

The modifier private provides the highest protection and lowest visibility: The private decorated domain, method, and nested type, which can only be accessed in its definition class.6.3.1 PrivateThere will be some procedural restrictions in the various books, such as:★ Modify all member variables with private (make all Member Variables private.).★ Modify any helper method with private. (Make any helper methods private).These heuristic rules are a self

Suggestions for Java concurrent programming using immutable objects whenever possible In a concurrent application environment, immutable objects have the following advantages: (1) Immutable objects, once created, cannot be modified by any threaded process, so there is no need to use a synchronization mechanism to protect their properties. (2) There is no data consistency problem with immutable objects.

Nonsense opening Today, I started to learn Java concurrent programming practices, which many experts have recommended. So in order to leave some books on the road of concurrent programming, I also have this blog post. Today, I am mainly studying the task execution section, which mainly describes the task execution defi

implementation of the lock introduced a number of optimizations, starting with jdk1.6, such as Lock coarsening (lock coarsening), lock cancellation (lock elimination), lightweight lock (lightweight Locking), Techniques such as biased locking (biased Locking), adaptive Spin (Adaptive Spinning) reduce the overhead of locking operations. The principle of spin-lock, which is similar to CAS spin, is even more optimized than CAS spin. For details, refer to the deep JVM lock mechanism 1-synchronized.P

?? Volatile is a familiar keyword in Java concurrency programming. Even if you have never used it, you will occasionally see it in technical books or blogs. The explanation of the volatile keyword is often taken over: the modified variable has visibility, but it does not guarantee atomicity. But exactly how to ensure visibility, what visibility is ... Such proble
