7 Which of the given choices are true?Select any two.
1 class Q3
2 {
3 public static void main(String arg[])
4 {
5 int[] a,c,d[];
6 int b[]=new int[0];
7 }
8 }
options :
1) All the variables a,b,c,d are arrays.
2) Only a,d,b are arrays.
3) We can declare an array with zero element.
4) We cannot declare an array with zero element.
i thought the answers were 2& 3 but when i checked it was as 1 & 3. please let me know whether i am correct or not and why in case i am wrong .

Why do you think "c" is not an array object?

Hi James,
I know where the confusion lies...keep following in mind..
When you declare like- int[] a,b,c,d; All variables become array variables.
But when you declare like..
int a[],b,c,d; Only a is an array, rest all are normal int variables.
Hope it helps u
Thanx

It would be more clear if it were written this way:
