how many languages are there in Java?
------------------------------------
java is an enormously popular language - the language
that made programming accessible for non sadists- c and c++ and assembly types.
but to know java u need to know other extra tools besides the language
. some have steep learning curves even to the established java developer.

e.g java swing- java swing library is large-its philosophy is simple but swing is language 2 after core java.

> frameworks:
-------------
if u want to do java u might as well face the truth,in the real world after u close that textbook, java programming means- frameworks.
infact other programmers use framework names to intimidate juniors.
heard of Pojo,hibernate, heard of apache.org?

after sun.com,make apache.org ur next home

Ant - a build tool. it has its own language,

the problem with java is - it doesnt get easier as u climb higher?
i mean- there is always some new tool to use and put in ur classpath.
its not consistent in philosophy?

see.
u learn jsp,then servlets,then ur a web developer right?

if it were php u were learning - yes!

but in web development with java-u never write jsp's by hand.
u use a framework? so why all the jsp and servlet learning.
a mind shift to learn the framework-not java's - philosophy ensues
then u'r done.

ok.
u learn jdbc for persistence.
u roll up your sleeves to write jdbc code-drivers in place.
but no- u don't ever write jdbc direct.
why?
u use a framework?
and u have to learn that language-the frameworks syntax and philosophy- to get going.

and so on and so forth.
visit apache.org.
u'v got many frameworks to learn.

and many files to download.
yes java is popular but java is the most expensive language to use?

jdk download- many mb's.

eventually,u can't just use an editor-why?
many third party platform's expect u to use - an editor?

e.g google android expects u to use eclipse-nothing else will do.
so u roll up your sleeves and wait for eclipse download to complete
then u begin learning - anoda language- the editor language:eclipse

oh,
the other platform wants - not eclipse but netbeans-
so.
buy 20 hours on a slow internet connection and wait for eclipse to download , and pray the download completes - use a download manager.

then , get netbeans tutorial- um u thought netbeans download came with all the tutorials bundled with the download? ur dreaming- go online
if u want to learn this language-the editor language- netbeans.

now java is popular. but java programmers are always on their toes?

learning anoda new language and philosophy.

compare this with other - old school ,not too modern language,
the syntax is straightforward and consistent.
after u've learnt the main core syntax- nothing else is forced on you,
other frameworks and platforms are 3rd party stuff-u pick and chose.
e.g
c++ has no idea of an ide, u can settle for microsoft's c++ editor
or use open source stuff- nothing down ur throat.

c++ has no gui- u can settle for qt,or whatever u like that's ur cup a tea. no frameworks that u have to learn all month.
there's enough in core programming computer science to keep a developer busy all his life besides programming frameworks and learning
but with new hot shiny languages like jave ,its the reverse,
they are new hot toys and frameworks on apache to keep you busy all ur life-at the end of the day,the science of computer science would be long gone to you.then how do you sharpen your thinking edge?
throug - frameworks!! visit apache.org!
