处理多线程同步问题

public class BusinessFor {
	private boolean bShouldSub = true;

	public synchronized void sub(int j) {
		//如果我不能执行,我将被设置为等待
		while (!bShouldSub) { 
			try {
				this.wait();
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
		
		for (int i = 1; i <= 10; i++) {
			System.out.println("sub: " + i + ",loop: " + j);
		}
		
		bShouldSub = false;
		this.notify();//唤醒
	}

	public synchronized void zhu(int j) {
		while (bShouldSub) {
			try {
				this.wait();
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
		
		for (int i = 1; i <= 100; i++) {
			System.out.println("main: " + i + ",loop: " + j);
		}
		
		bShouldSub = true;
		this.notify();//唤醒
	}

}

   这是一种多线程设计的一种思想,将线程同步的信息放在可syn同步的类中 。

   以下是启动线程测试

public class ThreadTongBu {
	
	public static void main(String[] args) {
		final BusinessFor businessFor = new BusinessFor();
		
		new Thread(new Runnable() {
			public void run() {
				for(int i=1;i<=50;i++){
					businessFor.sub(i);
				}
			}
		}).start();
		
		for(int i=1;i<=50;i++){
			businessFor.zhu(i);
		}
		
	}
	
}
