Array help/ declaring the scanner console

[Canh Ly]

Hi guys, im needed help with a compile error I'm getting for my code. I am using a scanner to read a dat file I already made with values from -1.0 and 1.0, but the problem I am getting is where I declare (below) the file to the console. The error I am getting is saying that it can't find the symbol, for the variable sounds1. Wondering what I was doing wrong here? It is declared in my main so theoretically it should work, but I have looked in the books and it looks the same. I'll put the first skeleton code so you can better understand my thinking behind my work. Thanks guys! I know posting help for assignments is frowned upon, but I'm not asking for help writing my code or anything just help and a little guidance thanks!!

		File filein = new File("sounds.dat");
		Scanner console = new Scanner(filein);

import java.io.*;

import java.util.*;


public class Mixer {
	
	public static void main(String[] args)
		
		throws FileNotFoundException {
			
		double[] sounds1 = new double[23];
		double[] sounds2 = new double[23];
		
		for(int i = 0; i < sounds1.length; i++)
		{
			
			sounds1[i] = console.nextDouble();
			
		}
		System.out.println("Sample 1\tSample 2");
		for(int i = 0; i <sounds1.length;i++){
			System.out.println(sounds1[i] + "\t" + "\t" + sounds1[i]);
		}
		
		File filein = new File("sounds.dat");
		Scanner console = new Scanner(filein);
	
	}	//end class
	
	public static void printA(double[] a)
	{
		for(int i = 0; i < a.length; i++)
		{
			System.out.println(a[i] + "\t");
		}
	}//end class
	
	public static void initA(Scanner console, double [] a)
	{
		for(int i = 0; i < sounds1.length; i++)
		{
			sounds1[i] = console.nextDouble();
			
		}//end class
		for(int i = 0; i < sounds1.length;i++)
		{
			
			System.out.println(sounds1[i] + "\t");
			
		}

	}
	
	public static void copyAB(double[] a, double [] b)
	{
		for(int i = 0; i < sounds.length; i++)
		{
			b[i]= a[i];
		}
	}//end class
	
//End Main Class

Solved it!! Moved the File filein above the sounds1 and sounds 2 I put it in the wrong order so the doubles were trying to get info from nowhere. And When I was getting errors for sounds1 in the classes for printA and init A I didnt switch the sounds1.length to a.length so it was syntactically incorrect and wouldn't correct. Here is the new code that compiles.

import java.io.*;

import java.util.*;


public class Mixer {
	
	public static void main(String[] args)
		
		throws FileNotFoundException {
		
		File filein = new File("sounds.dat");
		Scanner console = new Scanner(filein);	
			
		double[] sounds1 = new double[23];
		double[] sounds2 = new double[23];
		
		for(int i = 0; i < sounds1.length; i++)
		{
			
			sounds1[i] = console.nextDouble();
			
		}
		System.out.println("Sample 1\tSample 2");
		for(int i = 0; i <sounds1.length;i++){
			System.out.println(sounds1[i] + "\t" + "\t" + sounds1[i]);
		}
		
		
	
	}	
	
	public static void printA(double[] a)
	{
		for(int i = 0; i < a.length; i++)
		{
			System.out.println(a[i] + "\t");
		}
	}
	
	public static void initA(Scanner console, double [] a)
	{
		for(int i = 0; i < a.length; i++)
		{
			a[i] = console.nextDouble();
			
		}
		for(int i = 0; i < a.length;i++)
		{
			
			System.out.println(a[i] + "\t");
			
		}
