[code="java"]private Queue receivedData = new ArrayBlockingQueue(100);

public void receive(byte[] data, int length) {
    byte [] ldata = new byte[data.length+1];
    System.arraycopy(data, 0, ldata, 0, data.length);
    ldata[data.length]=(byte) length;
    this.receivedData.add(ldata);   

    synchronized(receivedData){                 
        this.receivedData.notify(); 
    }                       

}

private class HandlingThread implements Runnable{

    public void run() {     
        while(true){                
                if(!receivedData.isEmpty()){
                    byte[] data = receivedData.remove();                        
                    dealReceiveData(data);                  
                }                       
                else{
                    try {
                        synchronized(receivedData){
                            receivedData.wait();
                        }

                    } catch (InterruptedException e) {
                        e.printStackTrace();

                    }
                }

        }
    }

用的blockingqueue 但是我想当队列空的时候wait 怎么操作呢
这里回复都没解决问题

不需要处理，ArrayBlockingQueue自动阻塞

[quote]这是一个典型的“有界缓存区”，固定大小的数组在其中保持生产者插入的元素和使用者提取的元素。一旦创建了这样的缓存区，就不能再增加其容量。试图向已满队列中放入元素会导致放入操作受阻塞；试图从空队列中检索元素将导致类似阻塞。[/quote]
