Answer 1

I think there is no need to write this line:
package age;

Next, you have to import java.util.*; at the beginning.
Then, you have to write "Scanner in= new Scanner(System.in); " this line for taking input,inside main() function since you have used in.nextInt(); for taking input.
Maybe your code should be like this:
