1.概述
由于上一个文章《Java OOD 线程》中的线程是父类主动监听childe,比较耗资源,现改进为childe类醒来后主动联系父类
2.代码
Test.java
class Child implements Runnable { private Dad dad; public Child(Dad dad) { this.dad = dad; } public void wakeUp(){ dad.feed(this); } @Override public void run() { try { Thread.sleep(3000); } catch (Exception e) { e.printStackTrace(); } wakeUp(); } } class Dad { void feed(Child c) { System.out.println("feed child"); } } public class Test { public static void main(String[] args) { Dad d = new Dad(); Child c = new Child(d); new Thread(c).start(); } }
3.运行结果
