Is there any other way to show this pattern by reducing the number of for loops used! If yes then please share.

Answer 1

// // Please ask for permission before copying the code below. Tried this one myself.
import java.util.Scanner;
public class Pattern3
{
public static void main(String[] args) {

Scanner sc= new Scanner(System.in);

int n= sc.nextInt();

for(int i=0;i<n;i++){

//This loop is for the spaces that are to be printed. The formula varies according to pattern.
for(int j=1;j<=n-i+1;j++){
System.out.print(" ");
}

//This loop is to print the stars to make a triangle
for(int j=1;j<=2*i+1;j++){
System.out.print("* ");
}
//To start each loop with new line.
System.out.println();
}

}
}

Thank you RKK . Actually I did try this before but I made a silly mistake. But now I know what mistake I did.

Answer 3

if you want your output to have four rows then you can use j<=2*i-1

for 5 rows use j<=2*i+1

Answer 4

Hey RKK but I guess I should use " j<=2*i-1" or the first line won't be printed correctly. Thanks for helping
