Java is not fully object oriented

There are lot of arguments around IT peoples whether Java is purely object oriented or not. According to me, Java is now a purely object oriented language as it has wrapper classes. So you can use Byte,Short,Long,boolean,Integer, Float,Double. instead of int, float etc. (there are a total of eight primitive types).

But since Java has those eight primitive types, the critics will say Java is not purely object-oriented.
