public static void main(String[] args) {
BlockingQueue queue = new LinkedBlockingQueue();
ThreadPoolExecutor executor = new ThreadPoolExecutor(3, 6, 1, TimeUnit.DAYS, queue);

for (int i = 0; i < 20; i++) {
executor.execute(new Runnable() {

public void run() {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println(String.format("thread %d finished", this.hashCode()));
}
});
}
executor.shutdown();
}
