This is a link only answer. Remember that Stack Overflow's goal is to provide a repository of answers to questions that can be of use to future programmers and that links can rot, rendering the question unable to fulfill SO's goal. You can salvage it by summarizing the content of the link and explaining how it would solve the asker's problem. — user4581301 37 secs ago

Also, please read Open Letter to Students with Homework Problems. You can't just dump your problem statement here and expect us to do it for you. It's also a good idea to take the tour, read about what's on-topic in the help center, and How to Ask. — Chris 43 secs ago

You seem to have failed to grasp the basic concepts of this site, which is that it is a site for questions related to programming (code) or use of programmers tools (IDEs, compilers, etc.). You may find it helpful to review the help center guidelines to refresh your understanding of what is (and is not) appropriate to ask here. — Ken White 9 secs ago

Welcome to Stack Overflow. SO is a question and answer page for professional and enthusiastic programmers. Add your own code to your question. You are expected to show at least the amount of research you have put into solving this question yourself. — Cyrus 14 secs ago

Not familiar with the topic, but looks like you could use WebRTC: Can I implement a video chat in an app without any third party SDK? and Real time video communication functionality in android without 3rd party services. (I just searched for "make video call in Android App without using any Third Party SDK" and found those immediately.) — Markus Kauppinen 37 secs ago

@AshleyMills, if Apple provided API for everything, what would we do? Aren't we programmers? =^) — Asperi 19 secs ago

As it is, this question and its answer are unlikely to help anyone else, unless they're solving the same assignment posed around cows and milk. A better question would focus around the software engineering problem, not the assignment it was encountered in. — Charles Duffy 6 secs ago

MAybe you want to post this in software engineer. StackOverflow is more for code-specific questions so if you have a problem with your code implementing this, post it here — Tomerikoo 21 secs ago

@Carsi Please see: Why is “Is it possible to…” a poorly worded question?. — Progman 1 min ago

@markspace No. There's a SecurityManager that filters out configurations to DAOs previously approved by programmers. — DGoiko just now

I'm sure I speak on behalf of A LOT of programmers when I say how much I appreciate people like you and those working on H3. None of what I do would be possible without you and them, so MANY THANKS! — hgale 9 secs ago

and for those cases I decided to enable the requested dangerous function. Most poeple will never use it, in my case I'm providing my test subjects with functions already baked that hide those complex thought from them, so they can just define what they want to do with the text they're processing. On the other side, if this is actually used by programmers, there are some Reflection based functions that would allow them to do virtually anything, as they're assumed to be trusted parts (they could put malicious code into the companies code anyway without this). — DGoiko just now

So all this trouble comes because in Alpha, during one of the tests for those functions, the thing was not able to infer passing ArrayList to foo(List) was actually legal, and marked it as non-compilable, so I wanted to give programmers the closest experience than when directly using Java, — DGoiko 44 secs ago
