java 多线程打印ABC

方法千千中，开始看到这个，我立马想到了cyclicBarrier，能让ABC在打印在一组，可是控制不了ABC打印的顺序

 

后来自己用了一个最简单的synchronize的循环实现了，可以感觉没什么成就感

 

最后看了网上一个例子，思路很有意思，但是也不是我想要的，代码还是分享一下，请高手一眼扫过：

 

 

package dirk.zhang;

public class PrintABC {
	
	public static void main(String[] arg)
	{
		Data d = new Data();
		Threadp p1 = new Threadp("a","b",d);
		Threadp p2 = new Threadp("b","c",d);
		Threadp p3 = new Threadp("c","a",d);
		p1.start();
		p2.start();
		p3.start();
		
	}
}

class Threadp extends Thread
{
	private final  String name;
	private final  String next;
	private final  Data d;
	private int count = 10;
	
	Threadp(String name,String next,Data d)
	{
		this.name = name;
		this.next = next;
		this.d = d;
	}
	
	@Override
	public void run()
	{
		while(count>0)
		{
			if(d.flagName.equals(name))
				synchronized (d) {
				System.out.print(name);
				d.flagName = next;
				count--;
				}
		}
		
	}
	
	private void printname()
	{
		System.out.println(name);
	}
	
}

class Data
{
	public String flagName;
	public Data()
	{
		flagName = "a";
	}
	
}

 

怎么样，看完之后感觉也很平平淡淡，谁有什么更好的方法来showshow
