1 object and 10 integers.

The object is the array itself, with inside it 10 integers (all with value 0).

See JLS - 10 Arrays...

In the Java programming language arrays are objects...

class neeti {

static int year[]; /*****************8DOUBT*********/

public static void main(String args[]) {
System.out.println(year);
}
}

/********** doubt*********************/

is there a object reference there --- the DOUBT line...or is it a primitive?

'year' is a reference variable. it points to a object that is an Array, and that array can only hold ints. the compiler is kind, and initialized each of those 10 ints to 0 for you.
 
My first bit of advice is that if you are going to be a mime, you shouldn't talk. Even the tiny ad is nodding:
