[IkaMusume]

Hello po gusto ko lang sana itanong kung paano palitan ang mga corners ng hollow box using for loop sa java

import java.util.Scanner;
public class Pattern1 {

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter row and col");
        int row = sc.nextInt();
        int col = sc.nextInt();
        for (int i = 1; i <=row; i++) {
            for (int j = 1; j <= col; j++)
                if((i==1 || i==col) || (j==1 || j==col))
                    System.out.print("*");
                else
                    System.out.print(" ");
           
            System.out.println();
           
        }
    }
}
