Print Index of ArrayList<String []>

Question

I have an ArrayList of String Arrays. The arrays themselves should be holding every word of text files passed in. Then, the arrays are stored in an index of the ArrayList. For some reason, it's not working. It's only storing one word per array. What I'm trying to accomplish is when I call for a index of the ArrayList, it should print out all the words from the text file that was stored in the array. Can someone please look at this and point me in the right direction? I really appreciate any feedback. Thank you in advance.

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.Scanner;

public class Main {
    public static void main(String[] args) throws IOException{
        String [] files = {"C:\\Users\\Kelvin\\Documents\\Hello.txt", "C:\\Users\\Kelvin\\Documents\\Mountain.txt", "C:\\Users\\Kelvin\\Documents\\Thanks.txt"};
        ArrayList<String[]> list =  new ArrayList<String[]>();
        BufferedReader reader;

        for(int i = 0; i < files.length; i++){
            reader = new BufferedReader(new FileReader(files[i]));
            Scanner in = new Scanner(reader.readLine());
            String [] words = null;
            while(in.hasNext()){
                String inputText = in.next();
                words = inputText.split("[ \n\t\r,.;:!?*--+(){}}]");
            }
            in.close();
            list.add(words);
        }
        System.out.println(Arrays.deepToString(list.toArray()));
    }
}

Move list.add(words); inside the while loop after words = inputText... statement. — Ambrish

You are missing this part here :

while (in.hasNext()) {
    String inputText = in.nextLine();//<----nextLine instead of next
    words = inputText.split("[ \n\t\r,.;:!?*--+(){}}]");
    list.add(words);//<----------Add your result to your List
}
