Is Java pure Object-Oriented ????

hi friends,
wat do u feel, Is java a pure object oriented language??? then wat is object oriented pgming ???

On "purity" as a measure of object-orientedness:
However, this definition is problematic in that it implies that "purity" is a valid concept. Yet, there is no accepted definition of the term "pure OO language". Despite years of discussion and argument on the net, and in other circles, I have never seen anyone present a definition of a "pure OOPL" that met with general agreement by others.
-- Robert Martin, founder, CEO, and president of Object Mentor Inc., software industry leader.
On the value of using "purity" as a measure of a programming language:
I will not go into the discussion about ``purity'' beyond mentioning that I think that a general purpose programming language ought to and can support more than one programming style (``paradigm'').
-- Bjarne Stroustrup, designer and implementer of the C++ programming language, etc.

Java is 100% pure object oriented language or not?

PLS help me...?
I am get confussed.
Java is 100% pure object oriented language or not?

the only full OO programming language on thisplanet
is SmallTalk.On your planet maybe. On mine, at least Eiffel
also exists, probably more unknown others too. Some
count Ruby, but I never looked at it.Ruby is pure OO too, FYI.
the only full OO programming language on thisplanet
is SmallTalk.Care to explain it in some more detail? What
exactly is 100% OO, b.t.w.?No, I don't careWow, what an incredibly unhelpful response.
In essence, 100% OO implies that every type within the language is an object. Since Java has primitive types like int, boolean, float etc, it cannot count as 100% OO.

Java is pure object oriented programing language or not why?

please clear
java is pure object oriented programing language or not why?

And there is some concepts of object orientation that
Java not implements like: Operator
Overloading and Multiple Heritage. But, i think
that we can live without those features.
And the sucess of Java is a proof of this.I don't believe that operator overloading and multiple inheritance are required aspects of object programming.

Why java is called pure object oriented.

i know that java is called as pure object oriented language.
why it is called so even though it has primitive datatypes and also it doesnot support multiple inheritance completely. it only supports in the case of interfaces but not in the case of classes. then why it is called pure object oriented.

Its because you cannot write an executable java program without creating an object. Well, you can:
public class a
public static void main( String a[] )
}In contrary to C++, there can be no variables or functions in the wild (outside a class).
You can not create an executable java program without creating a class (but not forcibly its instance, an object.)
The "pure object oriented" wording in this sense has not really much importance, it is rather a marketing ploy.

Is java 100% pure object oriented?

I am very confuse is java 100% pure object oriented language.
bcoz
1)object oriented means everything should be in object but
primitive data type is not object.
2) java don't support multiple inheritances which is one of the oop 's
concept

I'd say that java is 100% java. No more, noless.
I'm gonna say it's about 99.4738383% java. For
no
reason other than to confuse idiotsSomeone's always bumping their heads against
some
arbitrary theoretical purity when they aremissing
what was, is and always has been most important:
functionality.Functionality matters virtually nothing to thepeople
that post these "questions". All that matters is
being able to say the right thing in interviews so
they can get a job and get carried through their
career by people who actually know what they're
doing. See it all the timeHehe, who carries you whilst you post here all day

Is Java 100% Object Oriented?

Is java 100% pure OOP?
I said no.. the reason is we can use primitive data types(which is not a
object)also....and also static method which can be accessed without
creating objects...Hope u understood my problem.
Can anyone give clear idea about this and mention if anything wrong with
my answer.........

Hi Guys,
No, Java is not a pure Object Oriented Language.
Many languages claim to be Object-Oriented. While the exact definition of the term is highly variable depending upon who you ask, there are several qualities thati feel an Object-Oriented language should have:
* Encapsulation/Information Hiding
* Inheritance
* Polymorphism/Dynamic Binding
* All pre-defined types are Objects
* All operations performed by sending messages to Objects
* All user-defined types are Objects
Java fails in the fourth condition because Java has primitive types viz; int ,float etc.....
And it also fails at the fifth condition because it fails to satisfy the fourth condition.
Only three languages are pure Object-Oriented
* Eiffel
* Smalltalk
* Ruby
For other details u can visit the blog created by me at http://noviceinjava.blogspot.com/
Though it has just started it will certainly grow as people get to know bout it

What is the strict criteria for a Pure Object Oriented Language ?

Can a fully object oriented language qualify as a pure Object Oriented Language.fF not what are the exact criteria for qualifying a language as Pure Object Oriented Language.Any examples of both would be greatly appreciated.
Thanks in Advance.

I guess you can check the link
http://forums.sun.com/thread.jspa?forumID=31&threadID=725662 for this.
I have no idea what point you're trying to make by posting a link to that thread.
Again,if someone thinks that something does not exist,what's the point debating on it.There is no point in debating this.
I don't care,Me neither.
tell me the definition,Like I already said many times: there exists no widely accepted definition of what a "pure OO language" is!
So, I ask you yet again: what is YOUR definition of such a thing? ANd don't go posting links to articles or other threads: just explain in your own wording of what YOU think a "pure OO language" is, and I'll answer your question by telling you if Java fits that definition.
search on google,why do you need that are not answers to my questions I see it has no use arguing with you: you don't seem to understand me.
,but more irrelevant questions on my simple question.I see a chain of irrelevant question, starting with your original post.

Is Java 100% Object oriented programming language?

Hi,
Is java 100% Object orinented programming language?
If not then what is the reason?
Thanks in advance

Object oriented paradigm of programming says that everything in a programming world should felt like object mean: - "Abstract and Encapsulated" The paradigm is not completely satisfied by Java. Some of the feature that makes such violation are 1. Existence of primitives, which are manipulated in ordinary style. 2. Existence of mathematical operator handled also not like objects. These two essential characteristics make Java somewhat what is the question. But here again Java is big winner to make presence of wrapper classes to wrap up this difficulty or adaption. Moreover in Java 1.5 you will feel more free because of auto-boxing feature that make auto conversion of object to primitive and primitive to object.

Is java purely object oriented??

Please don't shot me...
I'm having this doubt. because there are primitive datatypes in java which are not objects
and also a java program is not an object of any class.its started from main..

Is Java purely Object Oriented Language ?

Hi All,
Can any of you java masters tell me whether java is a purely OOL or not ?
and if yes then what are those factor that make a language OO , and if not then why ?

Hi All,

Only oracle object tables to create object oriented database

Can we use only oracle object tables for a database and if it can be done, can we create pure object oriented database with oracle. How it can be done?
help..
thank you..

PriyashanthaHP wrote:
I have no my own definitions for OODB. There are lot in the internet. I'm asking, can't we use that OODB concept with oracle. And gave you an example with 'employee' and 'department' tables. I asked that can we create object tables for these two tables keeping their relationship
thank you..
There is no way to answer that without knowing what YOU mean by OODB.
See the database concepts doc
http://docs.oracle.com/cd/B28359_01/server.111/b28318/schema.htm
Nested Tables
You can create a table with a column whose datatype is another table. That is, tables can be nested within other tables as values in a column. The Oracle database server stores nested table data out of line from the rows of the parent table, using a store table that is associated with the nested table column. The parent row contains a unique set identifier value associated with a nested table instance.

Can I develop a 100% Object Oriented DB with Oracle 10g?

Hello!
I need to know if I can develop a pure Object Oriented Data Base? because I have been looking for this information, and I just found Oracle's arquitecture is oriented to relational object model.
Thanks!

Dear "925803",
1) You're asking this question in the Oracle Application Express discussion forum - not really related to generic Database questions. This Database forum may be more suited: General Database Discussions
2) The Oracle database is not an object-oriented database.

Why java is called as true object oriented language?

HI Friends,
Though few oops concepts is not supported , why java is called as truly object oriented language and C++ as not a purely object oriented language???? Please, if any one know , give me the answer.
Thanks to all.

few oops concepts is not supportedwhich concepts?
as far as i know...to be OO, you must supports
encapsulation, abstraction, inheritancxe, composition (aggretration, et all) and polymorphism. Java supports all those comcept..now..Java is a hybrid due to what Jverd has pointed out.
the only pure OO language that i know of is SmallTalk. they have Meta class that can create Class object. and all their primitaives are object.
C# comes close, but their Class are not object.

IS Java Is puer Object Oriented Language

Pls I don't agree that java is puer OO.
This is the example..
I have 2 classes
class One {
public void main( Strin...) {
Two t = t new Two();
t.print();
class Two {
public void print ( ) {
S.o.p(" Not a object Oriented");
Now if i compil the both the class ane run the
first classs java One
it prints the msg... is fine
buu now i change the access modifier of the class Tow of the method print() and private ..
and compile the class Two not the One...
then i run the class One..
still it prints the msg..
It does't give any error... untile i recompile the one.java with the Two.class the it says print() can not be accsed..
can u say now it violate.. the OOPs concept..

You have discovered a part of Java that when you think OO does not do what you would expect. The system itself does not act in an OO way, but this does not mean that the language is not. It may not yet be Component friendly in a way that allows you to write components and then dynamically deploy them while thinking of the deployed components as objects that are instances of the component ?class?.
It took me a long time to accept that every single person has a different concept of what OO means. I had someone at Sun (during an interview) tell me that for pure OO an accessor or mutater should do nothing more than return a member or replace the value of that member with the exact value in the parameter. (Needless to say I didn't want or receive that position although I still wouldn?t mind working for Sun :)
I always thought that a ~pure~ OO language had to be completely type safe. (or as close as you can get) There could be no run time type errors. Well, this counts out not only Java, but also Smalltalk.
I am also of the opinion that there should be no "base types" (no mater how they are handled under the covers) C# does this nicely.
Then there is Parametric Polymorphism, which can be done nicely by generic typing and will be available in Java soon. This addition to a language is invaluable in allowing the developer to think in an OO way.
Invariants are another language feature that some would require for OO.
The point is that everyone has a different set of opinions about all of these things. I am absolutely certain that my opinions are the correct ones, as is anyone who is passionate about OO.
In my opinion Generics and Accretions have really made Java come of age. It is finally a language that I will think of as OO enoug.
Hopefully some day we will also get asynchronous methods (instead of threads) a better defined contract specification, and do away (at least on the surface) with base types. Then it would be a real OO system.
Wait, wait, we could add orthogonal persistence, or at least a typed persistence. We could outlaw public member feilds, We could fix the typeing issues with interfaces, we could...
sigh At least Java is moving forward. It may be dog slow, but as someone recently told me, there are actualy people out there building real systems with Java and they need it to move slow enough to get their work done, so they can make money, so they can pay people to develop.
You got to make sure that while you are reaching for that pie in the sky, it doesn't fall on your face. But then I like a bit of slapstick.
