    Just that simple with JAVA StringBuilder

        public static void main(String[] args) 
    {
    Scanner in = new Scanner(System.in);
    int n = in.nextInt();

    StringBuilder builder = new StringBuilder();
    for (int i = 0; i <n ; i++) 
        builder.append(" ");
    int j = 0;

    for (int i = 1; i <=n; i++) {
        builder.replace(builder.length()-i,          
        builder.length() - j, "#");
        System.out.println(builder);
        j++;
    }

}
