Question

I’m taking in a text file and storing each word in an arraylist. However the problem is, when I iterate through the arraylist and print the contents, the words appear many times and not necessarily in the right order. Here’s a snippet of the code below:

 public static void main(String args[])
    {
        try
        {
            ArrayList storeWord = new ArrayList();


            Scanner scannerWord = new Scanner(new File("word"));

            while(scannerWord.hasNext()) {
                String word = scannerWord.next();{
                    storeWord.add(word);

                    Iterator itr = storeWord.iterator();
                    while(itr.hasNext())
                        System.out.println(itr.next());

                }

Does anyone know what the problem could be and how to fix it?
Thanks.

Try this

public static void main(String args[]) { 
    ArrayList storeWord = new ArrayList();
    Scanner scannerWord = new Scanner(new File("word"));

    while(scannerWord.hasNext()) {
        storeWord.add(scannerWord.next());
    }

    Iterator itr = storeWord.iterator();
    while(itr.hasNext()){
       System.out.println(itr.next());
    }
}

Your ‘print’ loop was nested in your ‘read’ loop.
