Java in a Nutshell, 5th Edition

Name

Executor

Synopsis

This interface defines a mechanism for executing Runnable tasks. A variety of implementations are possible for the execute( ) method. An implementation might simply synchronously invoke the run( ) method of the specified Runnable. Another implementation might create and start a new thread for each Runnable object it is passed. Another might select an existing thread from a thread pool to run the Runnable or queue the Runnable for future execution when a thread becomes available.

ExecutorService extends this interface with methods to execute Callable tasks and methods for canceling tasks. ThreadPoolExecutor is an ExecutorService implementation that creates a configurable thread pool. Finally, the Executors class defines a number of factory methods for easily obtaining ExecutorService instances.

public interface Executor {
// Public Instance Methods
     void execute(Runnable command);  
}
