functional interface that takes nothing and returns nothing
提问by deamon
Is there a standard functional interface in the JDK that takes nothing and returns nothing? I cannot find one. Something like the following:
JDK 中是否有一个标准的函数式接口，它什么都不带，什么都不返回？我找不到一个。类似于以下内容：
@FunctionalInterface
interface Action {
void execute();
}
采纳答案by Eran
How about Runnable :
Runnable 怎么样：
@FunctionalInterface
public interface Runnable {
/**
* When an object implementing interface <code>Runnable</code> is used
* to create a thread, starting the thread causes the object's
* <code>run</code> method to be called in that separately executing
* thread.
* <p>
* The general contract of the method <code>run</code> is that it may
* take any action whatsoever.
*
* @see java.lang.Thread#run()
*/
public abstract void run();
}
