yaa u know everything are object in java but only datatypes
is not object in java...if u use further these datatype as
a object then change data type into object by wrapper
classes...so this is the resion.....so u can easilly say
that java is not 100% object oriented language because of
using data types okay....
JAVA is not 100% Object Oriented as we can use primitive
datat types like int ,float in java also.we have to wrap
them into as Objet as the JVM can not treate them as
objects.In JAVA1.5 we no need to wrap them as Objects
because 1.5 provides auto wrapping up of primitive data
types.
