IT SHOULD NOT BE PRIMITIVE. IT SHOULD BE AN OBJECT. AND IN
JAVA WE CAN CREATE OBJECTS OF ANY TYPE USING WRAPPER CLASSES.

Answer / kameshwar
The primary key can't be a primitive type--use the
primitive wrapper classes, instead. For example, you can use
java.lang.Integer as the primary key class, but not int (it
has to be a class, not a primitive)
