Where else but in the Overstocked Haberdasherywill you find code like:
除了在Overstocked Haberdashery 之外的其他地方，您还能找到以下代码：
public class ThreadCreationTest {
public static void main(String[] args) throws InterruptedException {
final AtomicInteger threads_created = new AtomicInteger(0);
while (true) {
final CountDownLatch latch = new CountDownLatch(1);
new Thread() {
{ start(); }
public void run() {
latch.countDown();
synchronized (this) {
System.out.println("threads created: " +
threads_created.incrementAndGet());
try {
wait();
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
}
}
}
};
latch.await();
}
}
}
where he not only uses a CountDownLatchandan AtomicIntegerandsynchronized(this)andhandles an InterruptedExceptionapropriately, he even uses a double brace initialiserto start the thread!! Now if that is not epic javawhat is?
在那里，他不仅采用了CountDownLatch和一AtomicInteger和synchronized(this)和手柄的InterruptedExceptionapropriately，他甚至使用了double brace initialiser启动线程！现在，如果那不是史诗般的 java是什么？

Doug Lea's Concurrent Doubly Linked Listis an excellent example of Lock Freecoding.
Doug Lea 的并发双向链表是一个很好的Lock Free编码示例。
