写一个java线程池代码

Java线程池代码的例子如下：import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;public class ThreadPoolExample {
public static void main(String[] args) {
ExecutorService executor = Executors.newFixedThreadPool(5); for (int i = 0; i < 10; i++) {
Runnable worker = new WorkerThread("" + i);
executor.execute(worker);
}
executor.shutdown();
while (!executor.isTerminated()) {
}
System.out.println("Finished all threads");
}
}
