Can u please tell me that in my code how to put spaces so that it becomes hollow i am quite confused!

#1 
Scanner scn = new Scanner(System.in);
	int n =scn.nextInt();
	int nsp=4;;
	int nst=5;
	int row=1;
	while(row<=n) {
		
		//for spACE
		for (int csp=1; csp<=nsp;csp++) {
			System.out.print(" ");
		}
		//for stars
		for(int cst=1;cst<=nst;nst++) {
			if(row==1||row==n) {
				System.out.print("*");						
		}else {
			for(int i =1; i<n;i++) {
				if(row==2||row<n) {
					System.out.print();
				}
			}					
			}
		}			
		System.out.println();
		nsp--;
	row++;
	
		
			}
		
		
	}
	
	

}

Hey @kalindiyadav5
correct code :
Dry run this code If you don’t understand
import java.util.Scanner;

public class Main {

public static void main(String[] args) {
	Scanner scn = new Scanner(System.in);
	int n = scn.nextInt();
	int nsp = n - 1;
	;
	int nst = n;
	int row = 1;
	while (row <= n) {

		// for spACE
		for (int csp = 1; csp <= nsp; csp++) {
			System.out.print(" ");
		}
		// for stars
		if (row == 1 || row == n) {
			for (int cst = 1; cst <= n; cst++) {

				System.out.print("*");
			}
		} else {
			for (int cst = 1; cst <= n; cst++) {
				if (cst == 1 || cst == n) {
					System.out.print("*");
				}

				if (row == 2 || row < n) {
					System.out.print(" ");
				}

			}
		}
		System.out.println();
		nsp--;
		row++;

	}

}

}
