import java.util.Scanner;

public class DrawBox {
   public static void main(String[] args) {
       Scanner in = new Scanner(System.in);
       System.out.println("Enter the width and the height of our box.");
       int w = in.nextInt();
       int h = in.nextInt();
       // iterating for height
       for (int i = 0; i < h; i++) {
           // iterating for width
           for (int j = 0; j < w; j++)
               // printing horizontal lines only if it is starting row or
               // column
               if (j == 0 || j == w - 1 || i == 0 || i == h - 1)
                   System.out.print("*");
               else
                   System.out.print(" ");
           System.out.println();
       }
       /* Type your code here. */
