Arrange the following java statements in the correct order of execution to accept values into the array a[]:

(ii) int a[]=new int[10];
(iii) Scanner sc=new Scanner(System.in);
(iv) for(i=0;i<10;i++)

1. (i), (ii), (iii), (iv)
2. (ii), (iii), (iv), (i)
3. (iv), (iii), (ii), (i)
4. (iii), (i), (iv), (ii)
