Java - Scanner can't find symbol

Question

I am trying to read every word (from every line) from a file which is sent in through args.

It's just a simple text file:

aa bb cc d
dd ee f gg
xx yy zz

The scanner seems to not be able to find the scanner symbol.. Here is my code:

import java.util.ArrayList;
import java.util.Scanner;
import java.io.File;
import java.io.FileNotFoundException;
public class Args
{
    public static void main(String[] args)
    {
        ArrayList<String> wordArrayList = new ArrayList<String>();
        System.out.println(args[0]);
        File filename = new File(args[0]);

        if (args.length == 1)
        {


            try
            {
                Scanner scanner = new Scanner(filename);
                while (scanner.hasNextLine())
                {
                    while (scanner.hasNext())
                    {
                        wordArrayList.add(scanner.Next());

                    }
                }


            }
            catch (FileNotFoundException e)
            {
                System.out.println("Oops, file "+ filename + "not found.");
            }


        }
        else
        {
            System.out.println("Nothing to do.. Powering down..");
        }
    }
}

Does any1 know what I am doing wrong with the scanner here?

This is the Error code:

Args.java:24: error: cannot find symbol
                        wordArrayList.add(scanner.Next());
                                                 ^
  symbol:   method Next()
  location: variable scanner of type Scanner

Because in java methods name are case sensitive you should check how your method is named.

According to http://docs.oracle.com/javase/8/docs/api/java/util/Scanner.html your method is named next() not Next() .

Changing it to next() should fix the problem.
