testthreadsyn.java

这是理解java线程同步的一个小例子

public class TestThreadSyn {
	public static void main(String[] args) {
		T a = new T();
		Thread r1 = new Thread(a,"A");
		Thread r2 = new Thread(a,"B");
		r1.start();
		r2.start();
		
	}
}

class T implements Runnable {
	public synchronized void run() {
		for(int i=0;i<5;i++) {
			System.out.println(Thread.currentThread().getName()+"is synchronize!!");
		}
	}
}
