public static void main(String[] args) {

    for (int i = 1; i <= 5; i++) {
        for (int j = 5; j >=i ; j--) {
            System.out.print(" ");
        }
        for (int j = 1; j <=i; j++) {
            System.out.print("*");
        }
        for (int j = 1; j <i  ; j++) {
            System.out.print("*");
        }
        System.out.println();
