What is primitive data type?

[Ganesan Ramakrishnan]

Why java saying int as primitive data type and String as object

[fred rosenberger]

because that's what they are.

Java, in a sort of carryover from C/C++, has about a half-dozen primitive types. int, char, double, etc. they are not true 'objects' in that they don't have methods, member variables, or anything one would normally associate with objects.

a String IS an object. in fact, everything in java that is not a primitive is an object.

[Jesper de Jong]

To be precise, there are eight primitive data types in Java: byte, short, int, long, char, boolean, float, double.
