developerWorks有一个 贴出来做个引子吧
public class WorkQueue
{
private final int nThreads;
private final PoolWorker[] threads;
private final LinkedList queue;
public WorkQueue(int nThreads)
{
this.nThreads = nThreads;
queue = new LinkedList();
threads = new PoolWorker[nThreads];
for (int i=0; i<nThreads; i++) {
threads[i] = new PoolWorker();
threads[i].start();
}
}
public void execute(Runnable r) {
synchronized(queue) {
queue.addLast(r);
queue.notify();
}
}
private class PoolWorker extends Thread {
public void run() {
Runnable r;
while (true) {
synchronized(queue) {
while (queue.isEmpty()) {
try
{
queue.wait();
}
catch (InterruptedException ignored)
{
}
}
r = (Runnable) queue.removeFirst();
}
// If we don't catch RuntimeException,
// the pool could leak threads
try {
r.run();
}
catch (RuntimeException e) {
// You might want to log something here
}
}
}
}

jdk1.5里的java.util.concurrent.ThreadPoolExecutor 非常好用。
