Staircase

    public static void main(String[] args) {
    Scanner in = new Scanner(System.in);
    int max = in.nextInt();
    for (int i = 1; i <= max; i++) {
    	System.out.println(new String(new char[max-i]).replace("\0", " ") + new String(new char[i]).replace("\0", "#"));
    }
}

      Why so much tables? One is enough:)

      try (Scanner s = new Scanner(System.in)) {
    int n = s.nextInt();    
    char[] a = new char[n];
    Arrays.fill(a, ' ');
    for (int i = n-1; i >= 0; i--) {
        a[i] = '#';
        System.out.println(new String(a));
    }
}
