Never under-estimate the power of the "growing phase-shrinking phase approach"

public class Stars {
    public static void main (String []args) {
        final int MAX_ROWS = 9;
        int n = 6;
        String stars = "*";
        for (int row=0; row < MAX_ROWS; row++) {
            for(int i = 0; i < n;i++) {
                System.out.print(" ");
            }
            System.out.println(stars);
 
            if(row >= 4) {
                if(stars.length() == 1) {
                    break;
                }
                n++;
                if(row == 9) {
 
                }
                else {
                    stars = stars.substring(0, stars.length()-2);
 
                }
            }
            else {
                n--;
                stars = stars + "**";
            }
        System.out.println();
        }
    }
}
