newFixedThreadPool

public static java.util.concurrent.ExecutorService newFixedThreadPool(int poolSize,
                                                                      int queueSize,
                                                                      java.lang.String threadNamePrefix)

Create a new thread pool with fixed pool size, and max task queue size. When task queue is full, run task on current thread, this will block current thread, prevent from submitting more tasks. The Thread name are set as as pattern $threadNamePrefix-thread-$seq.

参数:

poolSize - fixed pool size

queueSize - max task queue size

threadNamePrefix - the thread name prefix

返回:

ThreadPool

newFixedThreadPool

public static java.util.concurrent.ExecutorService newFixedThreadPool(int poolSize,
                                                                      int queueSize,
                                                                      java.util.concurrent.ThreadFactory threadFactory)

Create a new thread pool with fixed pool size, and max task queue size. When task queue is full, run task on current thread, this will block current thread, prevent from submitting more tasks.

参数:

poolSize - fixed pool size

queueSize - max task queue size

threadFactory - for create thread

返回:

ThreadPool

newFixedThreadPool

public static java.util.concurrent.ExecutorService newFixedThreadPool(int poolSize,
                                                                      int queueSize,
                                                                      java.util.concurrent.ThreadFactory threadFactory,
                                                                      java.util.concurrent.RejectedExecutionHandler handler)

Create a new thread pool with fixed pool size, and max task queue size.

参数:

poolSize - fixed pool size

queueSize - max task queue size

threadFactory - for create thread

handler - handler when queue is full

返回:

ThreadPool

threadPoolBuilder

public static ThreadPoolBuilder threadPoolBuilder()

Return a new ThreadPoolBuilder

返回:

ThreadPoolBuilder

shutdownAndAwait

public static void shutdownAndAwait(java.util.concurrent.ExecutorService executor,
                                    java.time.Duration timeout)

Shutdown Executor and wait task finished.

Previously submitted tasks are executed, but no new tasks will be accepted. This method blocks until all tasks have completed execution after a shutdown request, or the timeout occurs, or the current thread is interrupted, whichever happens first. If thread is interrupted, or timeout occurred, will stop all executing tasks by interrupt thread, and cancel all waiting tasks.

参数:

executor - the executor to terminate

timeout - the timeout duration to wait tasks finished.

scheduleAt

public static java.util.concurrent.ScheduledFuture<?> scheduleAt(java.util.concurrent.ScheduledExecutorService executor,
                                                                 java.lang.Runnable runnable,
                                                                 java.time.Instant instant)

Schedule task at specific time. If the task's run time is already passed, schedule it right now.

scheduleAt

public static <T> java.util.concurrent.ScheduledFuture<T> scheduleAt(java.util.concurrent.ScheduledExecutorService executor,
                                                                     java.util.concurrent.Callable<T> callable,
                                                                     java.time.Instant instant)

Schedule task at specific time. If the task's run time is already passed, schedule it right now.
