java thread如何理解

[lilinew]

下面的thread如何理解，

这里
/**For each delay we have a DelayedWriter */
private List<DelayedWriter> _delayedSubscriptionLst = new ArrayList<DelayedWriter>();


调用的类来自
public class DelayedWriter extends Thread(.....)

[asdujiayong]

集合：泛型，集合_delayedSubscriptionLst里存放的只能是DelayedWriter线程类

[lilinew]

线程类在java有什么特点　？

[asdujiayong]

有了线程类，就可以开启多线程，可以看下java

[gerryliu]

想要了解线程的话还是先找点资料看看吧

[wmg494005678]

找相关资料看看把，一两句话说不清楚，java的线程挺乱的。。。有点晦涩

[lilinew]

举个例子
public class DelayedDBWriter extends Thread
------------


//start DelayedDBWriters--from DelayedDBWriter (all, except DELAY_0)
for(int i = 0; i < _delayedSubscriptionLst.size(); i++) {
_delayedSubscriptionLst.get(i).start();
}
