    try{
        System.out.print("Enter the number of stars:");
        Scanner sc=new Scanner(System.in);
        String name=sc.nextLine();
        no_stars = Integer.parseInt(name);
        //no_stars = (int)System.in.read();
    }
    catch ( Exception e)    {
        System.out.println("Error! Invalid argument!");
        System.out.println();
    } 
    printstars(no_stars);
}
public static void printstars(int n)
{System.out.println(n);
int i;
for(i=0;i<=n;i++)
{    
    System.out.println('*');
}
}
