Okay

#

public class Main
{
   public static void main(String args[]) {

    for (int i = 0; i <= 5; i++)  // row 
    {
      for (int j = 8; j <= i+1 ; j++) //col
      {
        System.out.print("* ");
      }
    
      
      System.out.println();

    {
        for (int i = 0; i < 5; ++i)  // row
        {
            // 0, 2, 4, 6, 8
            // 1, 3, 5, 7, 9
            final int n = (i * 2) + 1;
            for (int j = 0; j < n; ++j) // col
            {
                System.out.print("*");
            }

            System.out.println();
            System.out.println();

here's 3 versions of the code 🙂

#

if you don't want "double line" remove the last System.out.println()

#

if you want a xmas tree, you need to print blanks first

#

;compile java

public class Main
{
    public static void main(String args[])
    {
        System.out.println("."); //!< Only needed for compile java output
        for (int i = 0; i < 5; ++i)  //!< Row
        {
            if (true) //!< XMAS tree layout or not
            for (int k = 0; k < (4 - i); ++k) //!< Blank column
            {
                System.out.print(" ");
            }

            for (int j = 0; j < i; ++j) //!< Star column
            {
                System.out.print("**");
            }

            System.out.println("*");
            // System.out.println();
        }
    }
}

tropic linden ;compile java ```java public class Main { public static void main(String arg...

i think this is the easiest to understand wait so basically all i do is change the middle inside loo p right

#

and i think my mistake is i forgot to put when it increments to double star not single star also if u can can u explain like the j < i thats kinda confusing i think thats why i got stuck

#

thanks btw! appreciate it ❤️

#

double star is to avoid (I*2)

#

and <= to avoid +1

#

or put print("*") outside the loop for the +1
