Queue implementation

[MaximilianHeinrich]

Please implement the Queue interface. We are required by our teacher to use your tool for CS exams. Our current topic is Data Structure, and it's a little bit awkward and disruptive to create a workaround with Lists and LinkedLists just because there are no JDK 8 features included.

You can find the requests reference and usage

According to Javadoc these are the jdk-classes which implement Queue:

AbstractQueue, ArrayBlockingQueue, ArrayDeque, ConcurrentLinkedDeque, 
ConcurrentLinkedQueue, DelayQueue, LinkedBlockingDeque, 
LinkedBlockingQueue, LinkedList, LinkedTransferQueue, PriorityBlockingQueue, 
PriorityQueue, SynchronousQueue

Many of them (like LinkedList) implement Deque which extends Queue.

Which one would you prefer?

Honestly, I'm afraid I'm misunderstanding your question. Maybe you're missing a method of interface Queue?

Do you use the current version of the Online-IDE (https://www.online-ide.de) or the beta-version of the new one (https://new.online-ide.de)?

We were trying using the new beta-version of the Online-IDE.
We are missing the offer(e) method which is preferable to add(e) as highlighted in the javadoc.
I tried the example @MaximilianHeinrich provided and could solve the errors by using add(e) but it would be nice to use offer(e) especially if you need to use it with capacity-restricted queues.

I added offer(e) in https://new.online-ide.de and i'll upload it to www.learnj.de this evening.

Since the online IDE runs in the browser, both its compiler and its runtime library are coded in Javascript (more precisely: Typescript).
The Java standard library is very extensive, so unfortunately I can't implement it completely in typescript.
But if individual classes/methods are needed, I'd be happy to add them.

If you are interested in the details you can find the sourcecode of the new online-ide compiler on github.
