what makes java not pure object oriented language? [closed]

I think java is pure object oriented, but in real it is not. But i dont know why java is not pure object oriented language, please help me to find out the reason.

This is a homework question, right?

Primitive types, that's why. For instance try this:

int i = 42;
System.err.println(i.toString());

The usual objection is that Java is not "purely" OO because it has primitive types (int, double, etc.), which are not objects.

To make proof by contradiction: Java has int, and int, like all primitive types in Java, is not an Object. There are possibly more reasons, though.
