RoundRobin 方法中的线程
这是一个示例代码，如果线程大小为 3 则表示可以。我可以在哪里管理内存。如果线程大小为 50，则问题所在。我需要将线程大小设置为 5。完成的线程应该由其他人重用
Thread[] TCreate = new Thread[iThreadSize];
for (int i = 0; i< TCreate.length; i++) {
TCreate[i] = new Thread(new Runnable() {
public void run() {
lst.Add(this.getResult(url));
}
});
TCreate[i].setName("URL"+i);
TCreate[i].start(); }
for (int j = 0; j < TCreate.length; j++)
while (TCreate[j].isAlive())
Thread.sleep(10);
，任何人都可以帮助 setDaemon() 方法的用途。守护进程的目的是什么 请帮助我..提前谢谢
Here is a sample code if the thread size is 3 means its ok. where i can manage the memory. if the thread size is 50 there the problem lies. i need to set threadsize as 5. finished thread should be reuse the by other
Thread[] TCreate = new Thread[iThreadSize];
for (int i = 0; i< TCreate.length; i++) {
TCreate[i] = new Thread(new Runnable() {
public void run() {
lst.Add(this.getResult(url));
}
});
TCreate[i].setName("URL"+i);
TCreate[i].start(); }
for (int j = 0; j < TCreate.length; j++)
while (TCreate[j].isAlive())
Thread.sleep(10);
Can any one help what is use of setDaemon() method. what is purpose of Daemon
Please Help me.. Advance thanks

setDaemon控制线程是否为守护线程。如果程序到达 main 方法末尾时守护线程仍在运行，则不会阻止程序退出。非守护线程（用户线程）确实可以防止程序退出。setDaemoncontrols whether a thread is a daemon thread or not. If daemon threads are still running when the program reaches the end of the main method, it does not keep the program from quitting. Non-daemon threads (user threads) do keep the program from quitting.Java 已经包含了管理线程池的方法。
调用 Executors.newFixedThreadPool(5) 将为您生成一个包含 5 个工作线程的线程池。
之后，您可以分配将由池中的线程执行的 Runnables。
另请参阅：
Java already includes methods for managing Thread pools.
calling
Executors.newFixedThreadPool(5)will generate a thread pool with 5 worker threads for you.Afterwards you can just assign Runnables that will be executed by on of the Threads in the pool.
