stack.java

接着上次传入一些Java学习中的实验

package commu;


class Stack{
	public synchronized int getPoint(){return point;}
	public synchronized String pop(){this.notifyAll();
	while(point==-1){
		System.out.println(Thread.currentThread().getName()+":wait");
		try{this.wait();}catch(InterruptedException e){throw new RuntimeException (e);}
		
	}
	String goods=buffer[point];
	buffer[point]=null;
	Thread.yield();
	point--;
	return goods;
	
	}
	public synchronized void push(String goods){this.notifyAll();
	while(point==buffer.length-1){System.out.println(Thread.currentThread().getName()+":wait");
	try{this.wait();
		}catch(InterruptedException e){throw new RuntimeException (e);}
	}
	point++;
	Thread.yield();
	buffer[point]=goods;
	}
}
