output of a staircase

[Carolin Sha]

Hi guys,

New to programming, please see my code

import java.util.Scanner;
class LeftBottomTriangleNew2
{
    public static void main(String[] args) 
    {
        Scanner in = new Scanner(System.in);
			
        System.out.print("Enter number from 1 to 8:");
		int x= in.nextInt();
		
		    for(int j=1;j<=x;j++)
        {    
            for(int i=0;i<j;i++) System.out.print("*");
            System.out.println();
		}
			
			if (x<=0 && x>9)
				System.out.print("Invalid number!");
			else
				System.out.print("Enter number from 1 to 8:");
				
			}//end of if
			
        
	}//end of main

code compiled with output below -

Enter number from 1 to 8:4
*
**
***
****
Enter number from 1 to 8:

and

Enter number from 1 to 8:9
*
**
***
****
*****
******
*******
********
*********
Enter number from 1 to 8:

the staircase looks good,however I want to remove the last line and if user chooses 9 i want them to get message "enter number from 1 to 8" and do not print out the staircase.

what am i doing wrong?
any help would be appreciated.

Test the input value (x <= 0 && x > 9) before the for loops

…and go through that boolean expression carefully before use, and check what values you get
