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;
}
}
