File Reading code doesn't work

My code needs to print certain results to a file if the user types something, and if they type nothing just print it to the screen. I wrote the code, and am including it below, but once my program prompts the user it doesn't do anything and I don't understand why. I know the code is long, but is fairly logically laid out. If anyone knows why please give me some insights, Thank You.
Code java:
import java.util.*;
import java.io.*;
 
public class Project4{
	public static void main(String[] args)
		throws FileNotFoundException {
		Scanner input = new Scanner(System.in);
		System.out.print("File Name:");
		String fileName = input.nextLine();
		Scanner console = new Scanner(new File(fileName));
		int totalNumbers = console.nextInt();
		double[] filearray;
		filearray = new double[totalNumbers];
		for (int i = 0; i < totalNumbers; i++)
			filearray[i] = console.nextDouble();
		System.out.print("Output [type a file name, or push return");
		System.out.print(" to output to screen]: ");
		String s = input.next();
		System.out.print("There are " + totalNumbers);
		System.out.println(" numbers in your input file");
		if (s.length() == 0){
			printResults(filearray);
		} else {
			writeResultsToFile(filearray);
		}
		Arrays.sort(filearray);
		}
 
 
	public static double calculateMax(double[] filearray){
		double maximum = filearray[0];

	public static double calculateMin(double[] filearray){

					}
				}
				return minimum;
				}		
 
 
	public static double calculateMean(double[] filearray){
		double sum = 0;
			//calculates sum

			//calculates average
			double mean = (sum / filearray.length);
			return mean;
	}
 
	public static double calculateMedian(double[] filearray){
		  int middle = (filearray.length+1)/2;
    if (filearray.length%2 == 1) {
        // Odd number of numbers -- return the middle one.
        return filearray[middle];
    } else {
       // Even number -- return average of middle two
       // Must cast to double before division.

				if(filearray[j] == filearray[i]){
					count++;
					}

	return maxValue;
