java学习笔记.03——线程同步

run()
{
synchronized(obj)
{
...
}
}

public synchronized method() {}

Lock lock = new ReentrantLock();   //同步锁
Condition condition = lock.newCondition(); //控制wait和notify的类
condition.await();   // = wait()
condition.signal();  // = notify()

//常用操作
Lock lock = new Reentrantlock();
Condition condition = lock.newCondition();
run()
{
lock.lock();

while( ... )
{
condition.await();
}

...

condition.signal();

lock.unlock();
}
