In this Java pattern program, we show the steps to print the stars in an Alphabet N shape or pattern using for loop, while loop, and functions.
import java.util.Scanner;
public class Example
{
private static Scanner sc;
public static void main(String[] args)
{
sc = new Scanner(System.in);
System.out.print("Enter Rows = ");
int rows = sc.nextInt();
for (int i = 0; i < rows; i++)
{
System.out.printf("*");
for (int j = 0; j <= rows; j++)
{
if (j == rows - 2 || j == i - 1)
{
System.out.printf("*");
}
else
{
System.out.printf(" ");
}
}
System.out.println();
}
}
}
Enter Rows = 14
