请教一个java中的同步问题

[haitingpu]

如果有三块内存a b c,一个线程writer循环有次序的往这三块内存中些数据，a->b->c->a->b->c...,然后还有一个线程reader也是有次序地从这三块内存中取数据，这个怎么实现？

package XueLer;

public class TestThreadABC  implements Runnable{
	
	public static SynchronzedLock lock = new SynchronzedLock();
	public static char mark ='A';
	public char name;
	
	public TestThreadABC(char name){
		this.name = name;
	}
	
	public char getName(){
		return name;
	}

	public void run() {
		while(SynchronzedLock.count < SynchronzedLock.total){
			synchronized (lock){
				if(this.getName() == mark){
					SynchronzedLock.count ++;
					System.out.println(this.toString());
					mark = (char)(((mark-'A')+1)%3+'A');
				}
			}
		}
	}
	
	public String toString(){
		return "Name : " + name +"    count : " + SynchronzedLock.count;
	}
	
	public static void main(String [] args) throws InterruptedException{
		Thread thread1 , thread2 , thread3;
		thread1 = new Thread(new TestThreadABC('A'));
		thread2 = new Thread(new TestThreadABC('B'));
		thread3 = new Thread(new TestThreadABC('C'));
		
		thread1.start();
		thread2.start();
		thread3.start();
	}
	

}


class SynchronzedLock{

	public static final int total = 100;
	public static int count = 0;
	
}

Synchronze
楼上方法楼主试了没

[haitingpu]

还有没有其他的实现方法，2楼的代码没有看明白

[bobo415]

将写跟读的方法都做同步处理下

[haitingpu]

还能写下具体的代码？
