returning a char array

So, I have a text file containing a series of characters that I need to manipulate later in the program. So right now I'm trying to write a method that puts the chars in the string into a char[], then returns the array. I've tried lots of different stuff, but the following code is the only attempt that didn't have lots of errors, it just doesn't display anything when I call reads(reader) in main.
The mistake is probably obvious, but we just started arrays.
Also, this is the first time I've posted in this forum, so am unsure how to format it properly. I know it sucks trying to read unindented code, but I honestly have no idea.



import java.io.*;
import java.util.Scanner;


public class Practice3
{
public static void main(String[] args) throws IOException {
Scanner reader = new Scanner(new File("answers.txt"));
System.out.println(reads(reader));
}

public static char[] reads(Scanner reader) {
int x = 0;
String line = reader.nextLine();
char[] answers = new char[line.length()];
while(reader.hasNext() && x <= line.length()-1) {
x++;
answers[x] = line.charAt(x);
}
return answers;
}
}
 
I agree. Here's the link: http://aspose.com/file-tools
