ReentrantLock线程锁 

1     public static void main(String[] args) {
2         Test tl = new Test();
3         Thread th = new Thread(tl);
4         Thread th1 = new Thread(tl);
5         th.start();
6         th1.start();
7     }

测试线程：

 1 class Test implements Runnable {
 2     static Lock lock = new ReentrantLock();
 3     @Override
 4     public void run() {
 5         lock.lock();//上锁
 6         Thread t = Thread.currentThread();
 7         
 8         for(int i=0;i<50;i++) {
 9             try {
10                 t.sleep(1000);
11             } catch (InterruptedException e) {
12                 // TODO Auto-generated catch block
13                 e.printStackTrace();
14             }
15             System.out.print(t.getName()+" :");
16             System.out.println("-");
17         }
18         lock.unlock();//解锁
19     }    
20 }
