Runnable接口和Thread线程类源码 Runnable是一个接口,接口内只声明了一个run()方法,声明如下: public interface Runnable { /** * When an object implementing interface Runnable is used * to create a thread, starting the thread causes the object's * run method to be called in that separately executin...

publicinterfaceRunnableFuture<V>extendsRunnable, Future<V>{/*** Sets this Future to the result of its computation * unless it has been cancelled.*/voidrun(); } 到目前为止我们可以发现,FutureTask构造器中可以接收一个Callable类型的对象,而FutureTask实现了Runnable,Future两个接口,所以当我们创建了一个Cal...
Runnable接口:public interfaceRunnable 明显可知两者:Thread类是Runnable接口的一个实现类,那么Runnable接口是何用? 文档解释: Runnable接口应该由那些打算通过某一线程执行其实例的类来实现。类必须定义一个称为run的无参数方法。 设计该接口的目的是为希望在活动时执行代码的对象提供一个公共协议。例如,Thread类实现了Ru...
然后Callable要怎么使用?为什么要设计出Callable?Runnable是不是有什么缺陷?ok,还是先看看Runnable的源码:可以看出Runable其实就是一个接口,同时使用了java的函数式函数@FunctionalInterface,所以是可以支持lambda表达式的,这是jdk8中的新特性 代码语言:javascript
