java-并发-Callable、Future和FutureTask

创建线程的2种方式，一种是直接继承Thread，另外一种就是实现Runnable接口区别：接口可以实现多继承缺陷就是：在执行完任务之后无法获取执行结果 Callable与Runnable java.lang.Runnable public interface Runnable { public ...

java多线程并发问题求解

父类中定义了几个成员变量String类型 a，b，c，这个父类被几个子类共同继承了，各个子类中在构造器内初始化了a,b,c变量，问多线程调用每一个子类时会产生并发问题吗？

Java序列化的并发问题

Java 实现了Serializable接口后，那么并发问题Java源码帮我们解决了吗？

聊聊并发-Java中的CopyOnWrite容器

Copy-On-Write简称COW，是一种用于程序设计中的优化策略。其基本思路是，从一开始大家都在共享同一个内容，当某个人想要修改这个内容的时候，才会真正把内容Copy出去形成一个新的内容然后再改，这是一种延时懒惰策略。从JDK1.5开始Java并发包里提供了两个使用CopyOnWrite机制实现...

从JDK源码角度看java并发线程的中断

线程的定义给我们提供了并发执行多个任务的方式，大多数情况下我们会让每个任务都自行执行结束，这样能保证事务的一致性，但是有时我们希望在任务执行中取消任务，使线程停止。在java中要让线程安全、快速、可靠地停下来并不是一件容易的事，java也没有提...

java 并发竞态条件（1）

竞态条件，说得通俗一点，就是线程A 需要判断一个变量的状态，然后根据这个变量的状态来执行某个操作。在执行这个操作之前，这个变量的状态可能会被其他线程修改。看一个例子 Java代码 import java.util.concurrent.atomic.Atomic...

从JDK源码角度看java并发的原子性如何保证

JDK源码中，在研究AQS框架时，会发现很多地方都使用了CAS操作，在并发实现中CAS操作必须具备原子性，而且是硬件级别的原子性，java被隔离在硬件之上，明显力不从心，这时为了能直接操作操作系统层面，肯定要通过用C++编写的native本地方...

Java并发——各类互斥技术的效率比较

既然Java包括老式的synchronized关键字和Java SE5中心的Lock和Atomic类，那么比较这些不同的方式，更多的理解他们各自的价值和适用范围，就会显得很有意义。比较天真的方式是在针对每种方式都执行一个简...
