如何將元素一次添加到另一個隊列中？

Question

我有一個類，它啓動所有的線程。

BlockingQueue<MyClass> otherQueue1 = new ArrayBlockingQueue<MyClass>(length); 
BlockingQueue<MyClass> niceQueue = new ArrayBlockingQueue<MyClass>(length); 
service = Executors.newFixedThreadPool(length); 
for (int k = 0; k < length; k++) { 
    service.submit(new MyClass(otherQueue1, id)); 
} 

在這種for循環，我想將這個創建MyClass到niceQueue。怎麼做？

Answer 1

BlockingQueue<MyClass> otherQueue1 = new ArrayBlockingQueue<MyClass>(length); 
BlockingQueue<MyClass> niceQueue = new ArrayBlockingQueue<MyClass>(length); 
    service=Executors.newFixedThreadPool(length); 
    for(int k=0; k < length; k++){ 
     MyClass myClass = new MyClass(otherQueue1, id); #save reference in local variable 
     niceQueue.add(myClass);       #add saved reference to queue 
     service.submit(myClass);       #submit, same as in your example 
    } 
}
