Java线程新特征之线程池

【线程池】

1、固定大小线程池

　　import java.util.concurrent.Executors;
　　import java.util.concurrent.ExecutorService;

　　ExecutorService pool = Executors.newFixedThreadPool(2);

　　pool.execute(t1);

　　pool.shutdown();

2、单任务线程池

　　ExecutorService pool = Executors.newSingleThreadExecutor();

3、可变尺寸线程池

　　ExecutorService pool = Executors.newCachedThreadPool();

4、延迟连接池

　　import java.util.concurrent.Executors;
　　import java.util.concurrent.ScheduledExecutorService;
　　import java.util.concurrent.TimeUnit;

　　ScheduledExecutorService pool = Executors.newScheduledThreadPool(2);

　　pool.schedule(t4, 10, TimeUnit.MILLISECONDS);

5、单任务延迟连接池

　　ScheduledExecutorService pool = Executors.newSingleThreadScheduledExecutor();
