The Future’s get() method will return null upon successful completion. Future submit(Runnable task) – submits a runnable task for execution and returns a Future representing that task.void execute(Runnable task) – executes the given command at some time in the future.We can execute runnables using the following methods : Generally, tasks are created by implementing either Runnable or Callable interface. ExecutorService executorService = new ThreadPoolExecutor(10, 100, 5L, TimeUnit.MILLISECONDS, The below statement creates a thread pool executor with a minimum thread count 10, maximum threads count 100 and 5 milliseconds keep alive time and a blocking queue to watch for tasks in future. We can choose an implementation class of ExecutorService interface and create its instance directly. Internally manages thread pool of 10 threads to run scheduled tasksĮxecutorService es = Executors.newScheduledThreadPool(10) 2.2. Internally manages thread pool of 2 threadsĮxecutorService es = Executors.newFixedThreadPool(2)

Executes only one threadĮxecutorService es = Executors.newSingleThreadExecutor() Using ExecutorsĮxecutors is a utility class that provides factory methods for creating the implementations of the interface. We can create an instance of ExecutorService in following ways: 2.1. Note that invoking the run() method of a Runnable interface in a synchronous way is simply calling a method. We can use this object to query the status of the thread and the result of the Callable object.ĮxecutorService is an interface and its implementations can execute a Runnable or Callable class in an asynchronous way. When we send a Callable object to an executor, we get a Future object’s reference.It’s call() method returns a result after the thread execution is complete.It’s similar to the Runnable interface with two benefits: Executor is responsible for executing the tasks, and running them with the necessary threads from the pool.Īnother important advantage of the Executor framework is the use of the Callable interface.Executor internally maintains a (configurable) thread pool to improve application performance by avoiding the continuous spawning of threads.With an executor, we have to create tasks that implement either Runnable or Callable interface and send them to the executor.

Task creation is mainly boilerplate code and is easily replaceable.

The framework mainly separates task creation and execution.

The framework consists of three main interfaces (and lots of child interfaces): If we have to develop a program that runs a lot of concurrent tasks, this approach will present many disadvantages such as lots of boilerplate code (create and manage threads), executing threads manually and keeping track of thread execution results.Įxecutor framework (since Java 1.5) solved this problem. In simple Java applications, we do not face many challenges while working with a small number of threads.
