Question 8: I am trying it using if and else. Is this a correct approach?

#1

package PatternsQuestions;

import java.util.Scanner;

public class ques8 {

public static void main(String[] args) {
	Scanner scn = new Scanner(System.in);
	int n = scn.nextInt();
	int nst = 1;
	int nsp = n-3;
	double mid = Math.ceil((double)n/2);
	
	

	for(int row = 1; row <= n; row++) {
		// work
		
		
		// made an if statement for the first and last 
		// row
		if(row == 1 || row == n) {
			for(int cst =1; cst <= nst; cst++) {
				System.out.print("*");
			}
			
			for(int csp =1; csp<= nsp; csp++) {
				System.out.print(" ");
			}
			
			for(int cst =1; cst <= nst; cst++) {
				System.out.print("*");
			}
			
			// an if statement when row = n/2;
		} else if (row==mid) {
			for(int csp =1; csp<= n/2; csp++) {
				System.out.print(" ");
			}
			for(int cst =1; cst <= nst; cst++) {
				System.out.print("*");
			}
			
			// an else statement for rest of the cases
		} else {
			for(int csp =1; csp<= nsp; csp++) {
				System.out.print(" ");
			}
			
			for(int cst =1; cst <= nst; cst++) {
				System.out.print("*");
			}
			
			for(int csp =1; csp<= nsp; csp++) {
				System.out.print(" ");
			}
		}
		
		
		
		// preparation
		System.out.println();
		if(row<n/2) {
			nsp--;
		} else if (row == mid) {
			nsp=n/2;
		} else {
			nsp++;
		}
		
	
	
	
	scn.close();

}

}}

Would really appreciate if you could give me a solution for this.

I’m confused if a this complicate approach is needed.
