Java also provides a thread pool that can return a value, as shown in the following example: Import java.util.concurrent.Callable; Import java.util.concurrent.ExecutionException; Import Java.util.concurrent.ExecutorService; Import java.util.concurrent.Executors; Import Java.util.concurrent.Future; public class Callableandfuture { /** * @param args * /public static void main (string[] args) { Executorservice ThreadPool = Executors.newsinglethreadexecutor ();

of the runnable interface, so the callable object cannot be used directly as target for the thread class. The callable method also has a return value--call () method, which cannot be invoked directly, but is invoked as a thread execution body. In the tool development package, Java 5 provides a future interface to represent the return value of the call () method in the callable interface, and provides a Futuretask implementation class for the
