Lock 框架
示例
通过使用显式锁，我们可以更加灵活的来处理线程同步。同时使用显式锁可以实现 synchronized 所没有的功能，下面是使用显式锁的一个示例：
import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;
/**

public class ReentrantLockTest {
private static int count = 1;
private static Lock lock = new ReentrantLock();
static class CustomThread implements Runnable {
@Override
public void run() {
lock.lock();
try {
count++;
Thread.sleep(1000);
System.out.println(Thread.currentThread().toString() + ": " + count);
} catch (InterruptedException e) {
e.printStackTrace();
} finally {
lock.unlock();
}
}
}
public static void main(String[] args) {
Thread thread = new Thread(new CustomThread());
Thread thread2 = new Thread(new CustomThread());
thread.start();
thread2.start();
}
}
