The primitive datatypes are nothing but the basic data types..like int,char,float,double etc..Char is a datatype which stores 2 bits of data..String has been derived from Char which takes more number of Char and integers..providing the more memory storage...Its not a primitive coz it is a basic datatype...Its advancement of char..So its not a primitive datatype

As balaji has asked a nice question that " why double is a primitive data type as it came from float?" As double is the default data type given to the floating point-numbers.Naturally when we declare float f =0;---------the memory occupied to it is double.Inorder to use memory effectively,we go for float as float f=0.0f;As double is not a two float.

There are two types of datatype 1. primitive 2. Object

I think String can also be primitive and Object type.

If u write String a = "rabbi"; then the String will be used as primitive datatype.

But If u write String a = new String("rabbi"); then String will be used by Object datatype.

I think both:

String a= "abc"; and String a = new String("abc");

are the same.

You r right Suri

Strings are immutable , so
String a = "abc";
is same as
String a = new String("abc");

Float and double both occupy fixed amount of memory irrespective of what number it holds. But String is an object. Memory allocation depends on the content

The Main reason behind is that when we talk about primitive data type

Lets say for ex int i=5 , it means in memory where we have i , if we will access the contents there we will get the value 5.

But in case of a String , when we say

String s="abe";

when we try to access the contents of s we get the address where we have "abc".

No its not like this, when a String is declared in double quotes, it actually means a reference from the String Pool, where this literal is already stored and for better understanding, one can see the intern method of String class.
