【多线程基础】- 多个线程顺序打印ABC

题目：3个线程名字分别是A，B，C 现在在console上连续打印10次 ABC 。

public class Test {

	public static void main(String[] args) {
		Thread a = new Thread(new Task("A",0));
		Thread b = new Thread(new Task("B",1));
		Thread c = new Thread(new Task("C",2));
		a.start();
		b.start();
		c.start();
	}
	
	static class Task implements Runnable{
		
		private String one;
		private int count;
		private static int num = 0;
		
		public Task(String one,int count){
			this.one = one;
			this.count = count;
		}
		
		@Override
		public void run() {
			
			int i = 0;
			while(i < 10){
				synchronized(Task.class){
					if(num % 3 == count){
						num++;
						System.out.println(one);
					}else{
						continue;
					}
				}
				i++;
			}
		}
	}
}
