I think that if you started learning code "a few mounths ago", you shouldn't even think to create what seem to be a such a big program. learn the basics first, start small with simple module and then only do the big stuff. Anyway, either you have people above you that knows the domain, and they are much more likely to find the solution, either you have programmers under you that also would be more qualified. I down vote because it is not the right SE site to as a recommendation question. Check here : softwarerecs.stackexchange.com — hl037_ 55 secs ago

Hmm... Few programmers take the time to look at what is in their object files. Consequentially, most programmers would not notice this result until the linker complains that the vtable is not found. So it might be reasonable to consider this a duplicate of Undefined reference to vtable. At least the highest-voted answer seems applicable. (I have an answer in there as well that is a bit more verbose, but it's further down the list.) By the way, the version of your compiler might be relevant. — JaMiT 55 secs ago

It would be great if you could explain WHY this works. Just providing free coding service to people, while it increases your "score", does very little to help teach people to be better programmers. — Graham 10 secs ago

Why is “Is it possible to…” a poorly worded question? — Andreas 36 secs ago

of course can (almost) always be improved in terms of performance, but it helps to state why you are trying to improve the performance of your code. There are countless bad reasons to try and optimize code, and often commenters here try to stop newer programmers from getting sucked down the rabbithole of trying to optimize in a way that is premature, or ultimately pointless. Your code is likely "fast enough" (again, explain why if you think it's not). If you are asking about curiosity of what is faster/slower in python, try to break it down into simpler, generally applicable components — Hymns For Disco 25 secs ago

We do use var and you'll see it alot in any codebase using LINQ extensively. Why? Because LINQ introduced many new things and programmers rejoice at not having to be explicit with method-scope variable types when dealing with LINQ. They go hand-in-hand. Which isn't surprising as both were introduced in .NET Framework 3.5 — MickyD 31 secs ago

Also note that the usage null != foo is sometimes preferred by seasoned C programmers, where it was easy to a accidentally write foo=null (an assignment) instead of foo==null (an comparison). There is no strict reason to do the same in java. — Gyro Gearless 22 secs ago

@mrEvgenX Are you asking who is going write the tests? The writing of tests will be done by several software engineers, which is why I am concerned with making it as intuitive and light on overhead as possible. — Andreas T 11 secs ago

But what if it runs on real device with higher java version, for example android 10 running higher java version than 1.8, Someone please throw more light, please. Thank you and upvoted as it helped me too. Google needs to change documenters first and programmers next. — Rushikant Pawar 22 secs ago

I think a fundamental problem with compiler writers' philosophy is that they assume that if a program receives inputs that would make it impossible to behave in useful fashion, all possible behaviors would be equally useless. Such a belief is not only dangerous, but also makes it necessary for programmers to write code in a way that prevents compilers from applying what would otherwise be useful optimizations. Preventing worse-than-useless behavior in useless cases should be easy and cheap, but it won't be if compilers can't recognize that some behaviors would be worse than useless. — supercat 52 secs ago

@Travis I did some PHP myself, and most of the thinking seems to overlap with ASP.Net. So I think it is the Web Programmers way of thinking. I could look at the ASP.Net Page Lifecycle, and instantly see the similarities in basic programm flow: docs.microsoft.com/en-us/previous-versions/ms178472(v=vs.140‌​) The biggest difference is that it is a whole lot easier to persist data between user inputs. — Christopher 42 secs ago

Actions that should be possible on all implementations shouldn't require non-portable constructs. If the Standard had a means of distinguishing loops that should, if endless, block any further actions, those that should block any observable behaviors that would depend upon values that will continuously change during repeated execution, and those which need not block anything, then it would be reasonable to say that programmers should use it. Since no such feature exists, however, it seems weird to suggest that programmers wanting optimization should be required to write their code... — supercat 17 secs ago

As you are seeing, some classes and methods enforce the application thread requirement, but not all strictly enforce it. It’s up to us as programmers to make sure the code executes in the correct thread. Of course, you are free to sprinkle your code with assert Platform.isFxApplicationThread() : "Not in JavaFX application thread!"; as much as you wish; it will incur no penalties. — VGR 12 secs ago

You can ask about homework here, but you can't just copy/paste the question and ask us to answer it; 3. Questions asking for homework help must include a summary of the work you've done so far to solve the problem, and a description of the difficulty you are having solving it. Please edit the question add this. Please, also read this Open letter to students with homework problems. So basically if you let us know where exactly you got stuck, we might be able to help you with that. — dbc 10 secs ago
