可以通过调用Executors类的static newScheduledThreadPool()方法获得一个调度的线程池。
语法
ExecutorService executor = Executors.newScheduledThreadPool(1)
示例
以下TestThread程序显示了基于线程的环境中newScheduledThreadPool()方法的使用。
import java.util.concurrent.Executors
import java.util.concurrent.ScheduledExecutorService
import java.util.concurrent.ScheduledFuture
import java.util.concurrent.TimeUnit
public class TestThread {
public static void main(final String[] arguments) throws InterruptedException {
final ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(1)
final ScheduledFuture<?> beepHandler =
scheduler.scheduleAtFixedRate(new BeepTask(), 2, 2, TimeUnit.SECONDS)
scheduler.schedule(new Runnable() {
@Override
public void run() {
beepHandler.cancel(true)&apos
scheduler.shutdown()
}
}, 10, TimeUnit.SECONDS)
}
static class BeepTask implements Runnable {
public void run() {
System.out.println("beep")
}
}
}
这将产生以下结果 -
beep
beep
beep
beep
beep
