Hello, I have been struggling with this program for a while and was wondering if anyone could help.

 

I am trying to make a program where the user inputs an int 0-9 and then it will print out something like this:

 

if user input=1 if user input = 3 I hope you guys get what im trying to say. so far i have:

1 **1

*21

321

import java.util.Scanner;

public class Lab07 {

public static void main(String[] args)

{

Scanner stdIn = new Scanner(System.in);

int x;

System.out.println("Enter a number 1-9: ");

x = stdIn.nextInt();

while (x <=0 || x>=10)

{

System.out.println("Please enter a number 1-9: ");

x = stdIn.nextInt();

}

int i,j,k;

for (i=1; i<= x;i++)

{

for (j=1;j<=x-i;j++)

{

System.out.print("*");

}

for (k=x-i;k<=9;k++)

{

System.out.print(k);

}

System.out.println();

}

stdIn.close();

}

}

THANKS!!!

Try something like:

 

for( j = 1; j <= x; j++ ) {

for( i = x; i >= 1; i-- )

{

if( i > j )

{

// print star

}

else

{

// print i

}

}

}
