        printFlag();
    }

    static void printFlag() {
        for (int i = 0; i < 5; i++) {
            for (int j = 0; j <= i; j++) {
                System.out.print("*");
            }
            System.out.println();
        }
    }

}

What about only outer layer of flag?

static void printNepalFlag() {
    int col = 5;

    for (int i = 0; i <= col; i++) {
        for (int j = 0; j <= i; j++) {
            if (j == 0 || i == j || i == col) {
                System.out.print(" * ");
            } else {
                System.out.print("   ");
            }
        }

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