Hey @Utkarshsingh5298291
There is no need to take the Val2 variable
correct code :
import java.util.*;

public class Main {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);

	int n = sc.nextInt();
	int nst = 1;
	int nr = 2 * n + 1;
	int nsp = 2 * n - 1;
	int nsp2 = 1;
	int nst2 = 1;

	// work
	int row = 1;
	while (row <= nr) {

		int val = n;
		int val2 = 1;

		int cst = 1;
		while (cst <= nst) {
			System.out.print(val + " ");
			cst++;

			val--;

		}

		int csp = 1;
		while (csp <= nsp) {
			System.out.print("  ");
			csp++;
		}

		cst = 1;
		val++;
		if(row==n+1) // n+1 th row me val ko val+2 kena h.
			val++;
		while (cst <= nst2) {
			if(row==n+1 && nst2==cst) {// In N+1 th row me extra 1 element print kr raha tha usko roka gayah 
				break;
			}
				System.out.print(val + " ");

			cst++;
			val++;
		}

		// prep-----------------------------------------------------
		if (row <= nr / 2) {
			nst = nst + 1;
			nst2 = nst2 + 1;
			nsp = nsp - 2;

		} else {
			nst = nst - 1;
			nst2 = nst2 - 1;
			nsp = nsp + 2;
		}

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

}
