java----------线程学习同步锁

在复习java的过程中，吧学到的代码和大家分享，共同学习。

public class ThreadSynchronize implements Runnable
{
Timer timer = new Timer();
public static void main(String args[])
{

ThreadSynchronize threadSynchronize = new ThreadSynchronize();
Thread thread1 = new Thread( threadSynchronize);
Thread thread2 = new Thread( threadSynchronize);
thread1.setName("t1");
thread2.setName("t2");
thread1.start();
thread2.start();
}

@Override
public void run()
{

timer.add(Thread.currentThread().getName());
}
}

class Timer{

private static int num = 0;

public synchronized void add(String name){//执行当前方法过程中锁定当前对象

num++;
try
{
Thread.sleep(1);
} catch (InterruptedException e)
{
System.out.print(name+"你是第几个" + num+"使用线程");
}
}
}
