要求:

子线程先循环10次,然后主线程循环100次,然后子线程循环10次,接着主线程循环100次......如此往复50次。

代码:

package cn.javaious.concurrence;

public class TraditionalThreadCommunication {
	
	public static void main(String[] args) {
		
		final Business business = new Business();
		new Thread(new Runnable() {
			
			@Override
			public void run() {
				// TODO Auto-generated method stub
				for(int j=1;j<=50;j++) {
					business.sub(j);
				}
			} 
		}).start();
		
		for(int j=1;j<=50;j++) {
			business.main(j);
		}
	}
	
}

/**
 * 高内聚
 * @author springtool suite
 *
 */
class Business {
	private boolean bShouldSub = true;
	public synchronized void sub(int j) {
		while(!bShouldSub) {
			try {
				this.wait();
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
		for(int i=1;i<=10;i++) {
			System.out.println("sub thread sequence of "+i+",loop of "+ j);
		}
		bShouldSub = false;
	}
	public synchronized void main(int j) {
		while(bShouldSub) {
			try {
				this.wait();
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
		for(int i=1;i<=100;i++) {
			System.out.println("main thread sequence of "+i+",loop of "+ j);
		}
		bShouldSub = true;
	}
}
