Scan Text And Add Each Word Alphabetical Listing?

I'm scanning my text and I want to add them into array list, but it is not easy. I want each word store from arrayList of a to z which is arrayList size is 26. Example:

arrayList a store string array of: an, and, apple, ...

arrayList b store string array of: be, become, became.....
.
arrayList z store string array of: zero, zone...

In my class, I create:

private static ArrayList<String[]> words = new ArrayList<String[]>(26); // to store all words

In main, I do while loop to get each words and store in words array,
