csharpjava: There a four major programming paradigms, they are:

Object-Oriented: "C#, Java, C++, SmallTalk, Python"

Functional: "Lisp, Scheme, Haskell"

Imperative: "C, Ada, Perl"

Logic: "Prolog, Sql, HTML"

Your choice of programming language will depend on the paradigm that is best suited for the application you want to develop. The most popular paradigm today is Object-Oriented paradigm which is a representation of the real world around us, this is why we have so many C#, Java and C++ programmers.

Fayimora:
I definitely love the OO way of thinking. However, the FP way is even more fun. Bringing them together(Scala I love you) is BRILLIANT!

WhiZTiM:
@csharpjava, suggesting Mozart, it doesnt look bad... And quite frankly, for the past 5+years of programming, I am just knowing(as in, in detail) about that Language!!
Do you code in it?? ...reasons?

Fayimora:
What's the advantage in bringing those 4 paradigms into one language? Not really seeing any reasonable advantage. Sounds like an overkill to me...might be wrong though so enlighten me

I'd rather have 5 tools that each do their respective job properly than have 2 that try to accommodate for all 5.

EfeAriaroo: @Fayimora ... very cool. I just feel lisps should be used more. They force one to know more about programming. Example, through my time learning Java I never read about prefix notation, how code can be data, higher order functional programming, or closures, or macros or lazy programming etc I feel programmers need to know about these things.

Fayimora:
@kambo Lisp has its flaws but talking about things like "poor GUI frameworks" is quite pointless, no pun intended.

kambo:
Yeah right. looks and convenience dont also matter right?
java's great strength comes from among other things having a bundled gui framework, and networking library. tell me a programmer who got started on java wouldnt find it uncomfortable expressing himself with a faceless (guiless ) alternative where he has to juggle from a list of unstandardized infrequently maintained often shabbily documented alternatives with variable performances. Think of wat the c,c++,ruby programmer goes thru to fit a face to his apps and tell me gui and similar conveniences dont matter.

lordZOUGA:
developing GUIs with qt C++ is probably easier than developing with java.

Fayimora:
ME! I did not care about GUIs for a while and I impressed a lot of folks with my work. I guess I'm more interested in writing functional and efficient systems than making nice GUIs.


When selecting a language for a task, a good GUI framework is barely a requirement, it is just a desired feature of the language. If you are using C/C++ then I doubt you are planning on writing a GUI in the first place. If you are using Ruby, you are most likely writing a utility or a web app, in which case you still do not need a GUI framework.

My point is, use the right tool for the job. For example, assume you have a webapp to build for someone. Personally, if I know Rails will be easier and better due to lots relationships and blah blah, I hack it in Rails. Otherwise, I might just hack a backend in Scala or JavaScript(NodeJS) and write a front-end in HTML/CSS/JS. I might even go crazier and hack the backend as re-usable components in multiple languages(currently doing something of this nature).

So it's up to you to decide, should I use Java because it has swing? or will a web service with a front-end serve me right here? or will a set of re-usable components be a better? or will language X be better because it has good FP and Concurrency support?

Just as a side note, I now consider Java "not worth learning" lol
