Doubt in patterns
Just think of it this way. You first need to print a line of n asterisks. Then for n - 2 lines you need to print asterisk followed by n - 2 spaces followed by an asterisk. Then simply print another line similar to the first line.

hello. sorry for bothering.
i was going through your instructions but problem a problem arised
my pattern is coming like this
6
and my code is
import java.util.Scanner;
public class tgf {
public static void main(String[] args) {
Scanner scn = new Scanner(System.in);
int n = scn.nextInt();
// row
int row = 1;
int nsp;
int nst;
while (row <= n) {
if (row == 1 || row == n) {
nsp = 0;
nst = n;
} else {
nsp = n - 2;
nst = 1;
}
// work for stars
for (int cst = 1; cst <= nst; cst++) {
System.out.print("*");
}
// work for space
for (int csp = 1; csp <= nsp; csp++) {
System.out.print(" ");
}
// work for stars
for (int cst = 1; cst <= nst; cst++) {
System.out.print("*");
}
// prep
System.out.println();
row = row + 1;
}
}
}
Hey @gautamparti
you needed to add space after each * and space too
also manage the ending stars for row!=n or 1
this is your corrected code:
please mark your doubt as resolved and rate as well
