Message1. Can't stand oop
Posted by: exxfile 2009-10-01 07:02:12
Hi All

I am a pretty green programmer  but I want to talk a little bit about my
history with learning so far .

I started with  java because I  accessed one forum  that talked about computer
programming and stated  that  java was the best programming language for
networking applications. So I started to  learn java  and I tried as  hard as I could to understand the  structure of object oriented programming ,  but the harder I tried the more obscure things got . Finally I got  fed up and threw  my java book away and said nuts to the whole thing .

Afew months later I couldnt stay away so I decided I would go back and  analyse the situation again .
I found a book called How to think like a computer scientist which is a must for anyone that is a beginner . ( Take it from a guy that is stupid enough to kick himself in the face a hundred times before getting something right ).

This  book cleared up  afew  mysteries that about programming , for instance putting a word to the good old fashioned way of doing things called procedural.

Why it was  so hard to learn .
Things  all the  dam books I read ( all supposed to be for complete noobs )  never explained .

That functions even existed ,  and  how arguments are  encoded into  functions. 
Everything I read was all about methods. ( Still  didn't make sense) the way they explained things .
Classes  contained both data attributes and  methods , meaning that I cannot use my own names for variables. Gee that makes a whole lot of sense ,  alot more of someone else code to  cipher . Encapsulation is what they  should have done to the inventor of oop .
Data hiding , nice !
polymorphism and inheritance ... how about  change the name and copy paste !
These books argued that oop was a better way to create modular coding by explaining how things were in the early  old days using goto statements.
Berrer known as spagetti code .
This is pure bs , procedural programming as everyone here  knows is  completely modular and structured and reusible . So what are these oop guys talking  about ?
I just hate oop and my attitude towards it is don't  fix what aint broke .
So now they say that python is one of the easiest languages to learn ,  but  what they don't tell you is that it's actually 2 languages now and they are  completely integrated with each other. oop python and procedural python , yummy .]
Go figure out the library with shitty documentation and 2  coding conventions to deal with , nice and easy right. For a beginner   NOT !
I am here and no one is going to tear me away from  classic REXX   except the mods and then  I ll sneak back in using a different account name HAHA !@

So someone just tell me I am not  so stupid for fealing the way I do even if you think I am a complete dud  just to make me feel better .
Rexx  noob

I have to agree. A guy here tried to explain why OOP was the way to go. If I boil it down to its simplest form (and what I understood), then classes are the same as "generalize subroutines". And ....

Ah - but with a class, you can drop it onto a printer, and it "knows" that it should print something. Yeah - and if I write a generalize subroutine that takes different argumets, one could be "print", one could be "open" etc etc. Oh, and did I forget to mention - if you write your code in a structered manner, it might look something like

ARG whatever
  WHEN whatever = 'PRINT'
    rc = print_routine.rex()
  WHEN whatever = 'OPEN'
    rc = open_routine.rex()
  etc etc 
and guess what. Yepp - the print_routine.rex routine can be called from any other rexx script.

Remind me again - what does oop do that's SO revolutionary ?

I don't use OOP very often, and if: only Reginald's basic implementation of it. 
Nonetheless the OOP criticism seems a bit excessive; there is some beauty in it.
Of course it’s not really new, technically you can achieve OOP behavior with many conventional programming languages and it has been certainly used in that way.
My possibly incorrect distinction of procedural coding and OOP is:
-    Procedural coding separates data (definition) from functions (coding) using and manipulating the data.
o    You may have data structures (copy books) in each using program
o    You may have access methods defined in each using program
-    OOP   keeps both units together.  There are some benefits in this proposal:
o    The program does not need to know how to access the data, even reading/writing of complex data structures are a black box. All you get is a logical record.
o    Changing/Enhancing the data structure is easy it is in one place
o    Improving/changing the access method is also simpler, the code is a centralized
o    Functions are centralized, duplicate coding is minimized, this again is a maintenance benefit    
o    You can have several instances of a method loaded and work in parallel on it. This is difficult to achieve with conventional languages.
All these OOP benefits can of course be achieved by modular design that separates data access, federates functions, etc. Therefore it’s quite true to say methods of OOP have been used for decades in the IT business, and it is of course nonsense to say conventional (procedural) coding must be spaghetti code.  Some experts say OOP is for IT as inventing the wheel. Usually I reply I rode bicycle long time before you have been planned.
