function界面什么都不带，什么都不返回

JDK中是否有标准的function接口，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(); } 

Answer 1

Runnable怎么样：

 @FunctionalInterface 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 executing * thread. * 
 * The general contract of the method run is that it may * take any action whatsoever. * * @see java.lang.Thread#run() */ public abstract void run(); }
