Java队列实现(Java Queue Implementation)

 我是Java新手并尝试使用： 
 
public static ArrayBlockingQueue<String> qu=new ArrayBlockingQueue<>(900);
...
qu.enqueue(MyString);
 
 要么 
 
public static Queue<String> qu=new Queue<>(900);
...
qu.enqueue(MyString);
 
 队列尖叫，声称它只是一个界面。 ArrayBlockingQueue不接受入队。 我觉得我犯了一些基本错误。 我的问题是：每次使用它时，我是否必须编写自己的Queue来实现接口，或者是否有就绪函数？ 如果是的话，我做错了什么？ 我的第二个问题是：什么是标准队列大小？ 根据我读过的规格，我认为它必须是我可能使用的最大值，但对于小型应用来说，900不是一个很大的空间接受者吗？ 

I am new to Java and trying to use:
 
public static ArrayBlockingQueue<String> qu=new ArrayBlockingQueue<>(900);
...
qu.enqueue(MyString);
 
or
 
public static Queue<String> qu=new Queue<>(900);
...
qu.enqueue(MyString);
 
Queue screams,claiming it's only an interface. ArrayBlockingQueue does not accept enqueue. I feel I'm making some basic mistake. My question is: do I have to write my own Queue implementing the interface every time I use it or is there a ready function? If yes, what am I doing wrong? My second question is: what is a standard queue size? From the specifications I've read I assumed it must be the maximum I may use but isn't 900 a bit big space-taker for a small application?
