java has all the oops concepts satisfied. (i.e abstract data types encapsulation polymorphism and inheritance). but still people say that java is not purely oop bcos it has primitive data types. but also java provides wrapper classes to use primitive data types as objects. so Java is a purely object oriented.

For 100 oops

we need 100 support in following things
1) inheritance 2) polymorphism 3) encapsulation

java support above three consepts but in inheritance java does not support multiple inheritance.

so that why java is not a 100 oops language.

now ? java not support multiple inheritance support. it is due to
Deadly Diamond of Death problem. To avoid this problem java use interface.

hai

java is not 100 oops is just because of all the codes are not included in class for example a jsp code is included in html where we donot have class so java is not 100 oops

Hi

Java is fully obeject oriented language but still If you take int float char are not the objects...these are the primitive data types.

Thats why some people saying that its not fully oops

Dear Actually Jsp itself based on special java classes

called servlets. study in depth will show u that each Jsp tag will be converted

into method of servlets like Declaration tag converts to init() method of servlet Scriptlet is alternative of service method and page directives are alternatives of import statements and jsp itself will be converted into a servlet

after execution. and you can see that every servlet of every jsp page

by exploring WEB-INF and then classes folder.

This perception is wrong that java is not pure object oriented because of jsp.

java is pure 100 object oriented programming lanaugage if excluding applets.

Java is not 100 oops language. Means 99.9 it's a pure oops language.

The reason is actually each and every thing will be treated as a object in java.But here we can use datatypes.With the help of wrapper classes we can access datatypes.So java is not follow the oops concept.So it's a 99.9 only pure oops language.

Java is object oriented program but it is not a 100 oops because still it supports for basic data types. It means they are not objects.

i e These are all not objects(int float). We will not use 'new' operator to create these data types. Hence Java is not purely object oriented programming language.

most of you people are getting the right point. But there is one more reason.

i.e. Every operation performed should be an message to object

by this i mean if we want to perform summation of x and y then as java support z x+y where as a pure object oriented way to perform the task is

Obj.z Obj.sum(x y);

the other reason is all those primitive datatypes(int float char etc.)
