Java有关多线程编程设计的类主要涉及两个包java.lang和java.util.concurrent两个包

java.lang包，主要是线程基础类

<1>Thread        <2>Runnable        <3>ThreadLocal

java.util包，主要是线程基础类和并发工具类

<1>基础线程类             Callable、Future、FutureTask        <2>容器类(线程安全)             ArrayBlockQueue             LinkedBlockQueue             SynchronousQueue             PriorityBlockingQueue             DelayQueue              ConcurrentHashMap              CopyOnWriteArrayList              CopyOnWriteArraySet         <3>锁类(java.util.concurrent.locks)            Condition             Lock                ReentrantLock, ReentrantReadWriteLock.ReadLock, ReentrantReadWriteLock.WriteLock            ReadWriteLock                ReentrantReadWriteLock        <4>原子类(java.util.concurrent.atomic)            AtomicBoolean             AtomicInteger             AtomicLong         <5>多线程控制类            线程池：（接口）Executor 、ExecutorService （类）ThreadPoolExecutor、 ScheduledThreadPoolExecutor             线程池工具类： Executors            并发控制器：Semaphore(信号量)、CountDownLatch(倒数闩)、CyclicBarrier(同步屏障)、Exchanger(交换机)
