多线程之间按顺序调用，实现A->B->C 三个线程启动，要求如下：
AA打印5次，BB打印10次，CC打印15次   接着 AA打印5次，BB打印10次，CC打印15次    。来10轮  

public class ThreadOrderAccess
{
	public static void main(String[] args)
	{
		ShareResource sr = new ShareResource();
		
		new Thread(() -> {
			for (int i = 1; i <=10; i++) 
			{
				sr.print5(i);
			}
		}, "AA").start();
		
		new Thread(() -> {
			for (int i = 1; i <=10; i++) 
			{
				sr.print10(i);
			}
		}, "BB").start();		
		
		new Thread(() -> {
			for (int i = 1; i <=10; i++) 
			{
				sr.print15(i);
			}
		}, "CC").start();		
		
	}
}
