Programming Tips - Java: Best way to enumerate a LinkedBlockingQueue

Date: 2012may14 Update: 2025sep22 Language: Java Level: novice Q. Java: Best way to enumerate a LinkedBlockingQueue A. Here is a full example:
import java.util.concurrent.LinkedBlockingQueue; class Demo { static LinkedBlockingQueue<String> gQueue = new LinkedBlockingQueue<String>(); public static final void main(String []args) throws Exception { gQueue.put("one"); gQueue.put("two"); gQueue.put("three"); for (String item : gQueue) { System.out.println("item=" + item); } } }
Output:
item=one item=two item=three
What if the queue is changed during your loop? That seems to be taken care of my the LinkedBlockingQueue. Or you could make a lock to protect the entire loop.
