Thinking in Java学习笔记Daemon线程和ThreadFactory接口

Daemon线程在主线程执行完毕后就会自动结束，设置Daemon线程setDaemon方法需要在run之前

ThreadFactory接口只有一个newThread方法，接受一个Runnable的实例对象，用以实现自定义的线程

package com.test.concurrent;

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.ThreadFactory;
import java.util.concurrent.TimeUnit;

public class DaemonFromFactory implements Runnable {

	@Override
	public void run() {
		// TODO Auto-generated method stub
		while(true){
			try {
				TimeUnit.MILLISECONDS.sleep(100);
				System.out.println(this+"     "+Thread.currentThread());
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
	}

	public static void main(String[] args) throws InterruptedException {
		// TODO Auto-generated method stub
		ExecutorService exec=Executors.newCachedThreadPool(new DaemonThreadFactory());
		for(int i=0;i<10;i++){
			exec.execute(new DaemonFromFactory());
		}
		System.out.println("All threads started!!!!!!!!!!!");
		TimeUnit.MILLISECONDS.sleep(500);
	}

}

class DaemonThreadFactory implements ThreadFactory{
	@Override
	public Thread newThread(Runnable runnable){
		Thread t=new Thread(runnable);
		t.setDaemon(true);
		return t;
	}
}
