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 代码运行次数:0 运行 AI代码解释 @FunctionalInterfacepublicinterfaceRunnable{/** * When an object implementing interface Runnable is...

Callable位于java.util.concurrent包下,它也是一个接口,在它里面也只声明了一个方法,只不过这个方法叫做call():1 2 3 4 5 6 7 8 9 public interface Callable<V> { /** * Computes a result, or throws an exception if unable to do so. * * @return computed result * @throws Exception if ...
