Answer Posted / arun kumar samal

no, java is not pure object oriented language due to in java
the primitives data
types(byte,short,int,long,float,double,char,void)are not
objects.to use this type we need each corresponding Wapper
implementation.
e.g:
class A{
Integer i;
public static void main(String... s){
A a=new A();
a.i=new Integer(10);//Boxing before javaSE 5.0
a.i=10;//AutoBoxing from javaSE5.0
}
