Is this approach correct? I got the required output but is there any other way to do this with lesser amount of code?

#1

package PatternsQuestions;

import java.util.Scanner;

public class ques7part2 {

public static void main(String[] args) {
	Scanner scn = new Scanner(System.in);
	int n = scn.nextInt();
	int nst = 1;
	int nsp = 1;
	
	for(int row = 1; row<=n; row++) {
		
		
		//working
		
		// if conditions for the first and nth row
		if(row==1 || row==n) {
		for(int count=1; count<=n-1; count++) {
		for (int cst=1; cst<=nst; cst++) {
			System.out.print("*");
		}
		
		for(int csp=1; csp<=nsp; csp++) {
			System.out.print(" ");
		}
		}
		} else { // condition for rest of the rows
			System.out.print("*");
			for(int spc = 1; spc<=2*n-3; spc++) {
				System.out.print(" ");
			}
			
		}
		System.out.print("*");
		
		
		
		//preparation
		System.out.println();
		
		
		
	}
	
	scn.close();
}

@sinuscoupon0s_4659768f9d9b587e For simple approach code will look like this :

import java.util.Scanner;

public class Main {

public static void main(String[] args) {
   Scanner scn = new Scanner(System.in);
   int n = scn.nextInt();
   int row = 1;
   while(row<=n){
       if(row == 1 || row == n){
           for(int i = 0; i < n; i++){
               System.out.print("* ");
           }
       }else{
           //single star 
           System.out.print("* ");
           //n-2 spaces
           for(int i = 0; i < n-2; i++){
               System.out.print("  ");
           }//single star 
           System.out.print("* ");
       }
   		row++;
           System.out.println();
   		
   }

   scn.close();

}
}
