JAVA 数据结构之Queue处理实例代码

java queue处理

实例代码：

import java.util.linkedlist;
import java.util.queue;
private static queue<framestruct> framequeue = new linkedlist<framestruct>();
private static lock lock = new reentrantlock();
private playerthread p = new playerthread();

从队列取数据进行处理：

private class playerthread extends thread {

    @override
    public void run() {
      framestruct frame;
      while(bplayrun)
      {
        if(bcanflush)
        {
          lock.lock();
          while((frame=framequeue.poll())!=null)
          {
            onframe(frame.buf, 0, frame.len);
            try {
              thread.sleep(30);
            } catch (interruptedexception e) {

            }
          }
          lock.unlock();
        }
      }
    }
  }

另一线程将数据放入队列：

framestruct frame = new framestruct();
frame.buf = new byte[bytecount];
frame.len = bytecount;
system.arraycopy(framedata, 0, frame.buf, 0, bytecount);
lock.lock();
framequeue.offer(frame);
lock.unlock();
