Java Concurrency Programming-the 2nd chapter-Thread Safety2. Thread Safety2.1 What is thread safetyThread-Safe classes: When a class is accessed by multiple threads, how these threads are executed alternately, regardless of how they are dispatched in the running environment, does not require the amount of synchronization or synergy in the code portion of the call

way to impose constraints on multiple parameters is to check all the parameters that a constraint must hold with multiple setter methods. Once an invalid argument is passed, the constraint fails immediately, rather than waiting for the build method to be called. The slight advantage of builder compared to constructors is that builder can have multiple mutable parameters. Constructors, like methods, can have only one mutable parameter.The traditional abstract factory implementation in

read operations, or by a write operation, but both cannot be performed concurrently. Read-write locks are a performance optimization measure that enables higher concurrency in certain situations. In practice, read-write locks can improve performance for data structures that are frequently read on multiprocessor systems. In other cases, the performance of the read-write lock is slightly worse than the perfo

(finalizer chaining)" is not automatically executed. If the class (not object) has an finalization method, and the subclass overrides the finalization method, the child class's finalization method must call the superclass's finalization method manually. The subclass is terminated in a try block, and the end method of the superclass is called in the corresponding finally block. Guarantees that the superclass's finalization method will be executed even if the subclass's finalization process throw

you to find the most compiled code by executing the counter, and then notify the JIT compiler to compile it in a method-by-unit way. If a method is called frequently, or the number of effective loops in the method is large, the standard compilation and OSR (stack substitution) compilation actions are triggered respectively. 1.4.6 Apache harmony/google Android Dalvik VMDalvik VM is not a Java virtual machine, it does not follow the

The compiler generates a public, parameterless default constructor only if the class does not contain an explicit constructor. This class cannot be instantiated as long as a class contains a private constructor. Example:1 //Tool Class2 Public classUtilityclass {3 //Private Constructors4 PrivateUtilityclass {5 Throw Newassertionerror ();6 }7 8 //Other operations ...9}　　Assertionerror avoid invoking the constructor inside the class to ensure that the class is not inst

up when a new entry is added to the cache. The Linkedhashmap class can implement the latter through its Removeeldestentry method. For more complex caches, you must use Java.lang.ref directly.A third common source of memory leaks is listeners and other callbacks.If the client registers callbacks in its own implementation of the API, but does not explicitly unregister, they will accumulate unless some action is taken. The best way to ensure that callbacks are immediately treated as garbage collec

only need to write some packages that can achieve our goal, we will adjust it based on our specific needs ". However, it is often because you have quickly extended the compiled simple tool and tried to add more features until you compile a complete infrastructure service. At this point, you usually stick to the program you write, whether it is good or bad. You have already paid all the cost for building your own program, so in addition to the actual migration cost invested by the general implem

Ownership of the stateThe object encapsulates its state, owning the state ownership, which is the ability to change the state, and if the object's reference is published, it is not the ownership of the object's exclusive state, but the ownership of the shared state with the other;2. Instance closure　　Object A is enclosed in another object B, and the path to access object A is known to facilitate thread safety, and if the data is enclosed in an object, access to the data is done through methods,

. volatilevariables are not cached in registers or in places that are not visible to other processors, so the volatile most recently written value is always returned when a variable of type is read.volatileYou should use variables only if they simplify the implementation of your code and validate your synchronization policies. If you need to make complex judgments about visibility when validating correctness, do not use volatile variables. volatilethe correct use of variables includes:
