Answer / §ẳȗ&am

Java is not pure object oriented. Because in java there are some concepts of wrapper classes like Integer, Float, Long etc. We cannot create the objects of these classes so this is violating the concept of OOPS that in OOPS everything must be in the form of objects and classes.

Answer / raktim mukherjee(con.begrip )

Hi Friend,

Java is not a fully object oriented language because of the
following reasons:

1)It uses primitive data type like int,float which are not
object

2)It does not support operator overloading multiple inheritance.

3)It allows static methods to call without creating the
instance.

Thanks n enjoy java.....

Answer / varahalaraju penmetsa

y do u say java is not pure OO Lang?

primitive datatyeps --> we can convert the primitive types
into wrapper types and they are 100% oo objects

Multiple Inheritance --> java does not support it, any way
we can achieve multiple inheritance using Interfaces and it
is 100% oo concept

abstract classes --> yes we cannot create objects for these
classes but by using these classes we are providing an
opportunity to other class to make an inheritance
relationship and Inheritance is 100% OO concept

and java supports method overloading and overriding for
polymorphic effect so java is 100% pure OO language

cheers,

Answer / alok painuly

java is not a fully object oriented programmin language,
its a "Pure object oriented language". Because a fully OOPL
must follwo all the characteristics of Object Oriented like
abstraction,polymorphism,encapsulation,inheritance etc...
But java does not support "Inheritance" property fully.. it
does not support Multiple inheritance,even we have
substitute as implementing Interfaces which allow multiple
inheritance but ist pure not fully..
So JAVA is a "Pure Object Oriented PL"..

Answer / adarsha

JAVA IS "THE" PERFECT OBJECT ORIENTED PROGRAMMING LANGUAGE.

whatever may be the oops concepts which are not supported by
JAVA like multiple inheritance and operator overloading etc
they hav been removed from java just to reduce the complexity.

Main reason i m telling java is OOL because everything in
java can represented in the form of "object" and thats wat
the main objective of object oriented programming language.

Answer / giridhar gangapatnam

The following reasons put forward by many people to say java
is not a purely object oriented programming language.

1.purely object oriented(oo)means it should contain only
classes and objects.It should not contain primitive data
types like int,float,char etc.since they are neither classes
or nor objects.

2.In pure oo languages we should access every thing by
message passing(through objects). But,Java contains static
variables and methods which can be accessed directly without
using objects.

3.Java does not contain multiple inheritance. It means an
important feature of oo design is lacking.So, how can we say
it is purely oo programming language.

No doubt Java is purely oo programming language. The
preceding points represent lack of in depth understanding of
java.

1.Even if java has primitive data types, these data types
are used inside the class and never outside of it.So, they
are part of a class. See the API specification of the class:
'Class'. Java specification says that all the arrays and
primitive data types (boolean,
byte,char,short,int,long,float,and double) and the keyword
void are also represented as objects of the class 'Class'.

2.Even static variables and static methods are written
inside a class. When accessing them from outside, we should
use classname. It means they are part and parcel of class
definition and should not be considered as individual
elements. For reducing memory utilization, only one copy of
them will be created in memory and shared by all objects.

3.Any purely oo language should follow all the 5 features of
oops. They are 1.Classes and objects. 2.Encapsulation
3.Abstraction. 4.Inheritance. 5.Polymorphism. Remember java
contains all these features and hence it is purely oo
language. Just because java does not contain multiple
inheritance, we should not say it is not purely oo language.
Multiple inheritance is not the main feature of oops, it is
only a sub feature of inheritance.

Answer / delnaz

Java is partially object oriented because -:
1. It does not support primitive data types. Hence their
object need to be created using wrapper class.
2. A language is said to be fully object oriented if it
supports classes,objects,inheritance and polymorphism, but
java does not support multiple inheritance or operator
overloading.
3. JVM directly calls main method without calling object.

Answer / elango

Java is object oriented language but not fully object
oriented language. because it does not support multiple
inheritance.

Answer / akshay

As owner of answer 20 said main(Sring []) is called without
creating object but u r forgetting that main() method
belongs to class only. it is static method. it is not global
function as we declare in C,or friend function like C++
