Androidology - Part 2 of 3 - Application Lifecycle

@mlanovoy- Though I do agree that Java is superior to C++ in some ways, you are just proving to them why they should develop in C++. When dealing with limited memory and processor power of a cell phone, you want speed and low level languages such as C / C++ can achieve such a goal

@zenhemmo Java is by far better than C++ as language. Altho, Java is inferior to such languages as C#, Scala, Nemerle, F#, Python, Ruby ect

mlanovoy,
are you joking? C++ is a compiled language, Java is an interpreted one. By its nature, C++ exceeds Java in performance many times. Why do you think system programming is done in C++, never in Java? And comparing languages like you do is meaningless, because every language has its own place.

@zenhemmo Well, you need to get some clue regarding "compiled" "interpreted" next time before you make any judgements.
Java is NOT interpreted language. Java programs are compiled into intermediate form - bytecode - which is then compiled (!) into machine codes, machine codes being executed just like for any unmanaged program - by CPU and NOT by interpreter as you seem to think in your delusion.

mlanovoy,
you are correct about Java code being bytecode, I meant to say that Python is a interpreted one (as you mentioned it on your list). The speed difference can be clearly seen in algorithms - C/C++ compilers generate way more efficient code than Java ever does. Not to mention that C++ allows low level access and direct memory access (Java has a garbage collector).

@zenhemmo There is different measures of efficiency. Very few situations where C++ code will really be "way more efficient". Java programs for example are more efficient than C++ because they consume much less storage (I'm speaking about their size). For such devices as phones with limited size of ROM it may be more critical than insignificant 10% difference in speed of computation (0.09 instead of 0.1 seconds for example for some rarely called but heavy function).

@zenhemmo As for perfomance Java in fact MAY be slower but not more then 200-300%. It may be noticable for very few tasks. Usually it's CPU heavy computations such as math/cryptography/games for majority of other apps the difference is insignificant.
In fact on certain tasks Java may even outperform C++.

@zenhemmo As of system programing - I personally KNOW unlike you why it's done in C (and not C++ as you think, btw) - it's NOT because of performance its because C is very low level language where you can directly work with system heaps/stacks, access IO ports ect, which is impossible (almost) for managed environments.

And, btw, if you think that system programming may not be done in managed, go check Singularity.

@zenhemmo Anyways, I was comparing LANGUAGES not execution environment and not the compiled code. As *language* C++ is fugly. Even new C++0x standard for which is still in development is too an ugly language. And by language I mean language syntaxis.

@RedClownKnight C++ as language is indeed crap. Altho, it's only really viable (a long with pure old C) language to develope on a system low level; and performance critical application.
