Mohit wanted to design a program using scanner class. Due to some confusion, he could not complete the program and has left some places marked with (i), (ii), (iii) and (iv) to be filled with the keywords/expression, as given below:

(i) java.util;   
class Sample   
{   
public static void main(String args[])   
    {   
    (ii) num;   
    Scanner inp = (iii) Scanner(System.in);   
    System.out.println("Enter a number:");   
    num=(iv);   
    if(n % 2 == 0):    
        System.out.println("Even number");
    else:
        System.out.println("Odd number");
    }
}

Help him to complete the program by answering the following questions:

(a) What keyword/expression will be filled in place of (i)?

(b) What keyword/expression will be filled in place of (ii)?

(c) What keyword/expression will be filled in place of (iii)?

(d) What keyword/expression will be filled in place of (iv)?

(a) import

(b) int

(c) new

(d) inp.nextInt();
