java - filling array gradually with data from user -

I am trying to fill an array with the input words by the user. Each word should be one letter lower than the previous and one letter less than the next one. Their length is equal to the table row index, counting from 2. Words end up making a one-way pyramid, such as:
A
AB
ABC
ABCD

  scanner sc = new scanner (System.in); System.out.println ("height of the array:"); Height = sc.nextInt (); String [] word = new string [height]; For (int i = 2; i  i-2 || words [i-2] .length () & lt; term [i-3] .length ()) {words [i-2 ] = Sc.next (); }}  

How can I limit the readings from the scanner to fill the requirements? Currently loop does not affect the scanner exactly: /

This is not the text of the house. I am trying to create a simple application and then GUI for it.

• read height to scanner (What is the price?)
• Are you sure you want to list & lt; String & gt; and other dynamically mountable data structures?
• What if the length requirement is not met?
• Why 2 and -2 offset?
  • When i = 2 , you can also reach the word [i-3] . Which will throw ArrayIndexOutOfBoundsException

    This is a rewrite that clarifies the argument:

      scanner sc = New Scanner (System.in); Println ("height?"); While (Sc.hasNextInt ()) {System.out.println ("int, please!"); Sc.next (); } Last int n = sc.nextInt (); String [] arr = new string [n]; {String S; For Int L = 1; L & lt; = N; L ++} Do {system.out.println ("length" + L + ", please!"); S = sc.next (); } While (s.length ()! = L); Arrival [L - 1] = S; } (String: arr) {System.out.println (s); }
