Executor 框架便是 Java 5 中引入的,其内部使用了线程池机制,它在 java.util.concurrent 包下,通过该框架来控制线程的启动、执行和关闭,可以简化并发编程的操作。因此,在 Java 5 之后,通过Executor 来启动线程比使用 Thread 的 start 方法更好,除了更易管理,效率更好(用线程池实现,节约开销)外,还有关键的一点:...
在java的多线程开发中Runnable一直以来都是多线程的核心,而Callable是java1.5添加进来的一个增强版本。 本文我们会详细探讨Runnable和Callable的区别。 运行机制 首先看下Runnable和Callable的接口定义: @FunctionalInterface public interface Runnable { /** * When an object implementing interface Runnable is used *...
