Reading files for characters

I am working on a program where the user creates a file, enters a certain character in the program, and the program displays the entered character from the file and how many times it is written in the file. Any kind of push or help would be extremely appreciated. Everything with the program is working fine, except the while(fileScan.hasNext()) {}, I am needing some help figuring this out.

import java.util.Scanner;
 import java.io.*;
 
 public class FileLetterCounter {
 	 public static void main(String[] args) throws IOException {
 	 	 
 	 	 // declare variables
 	 	 String fileName;
 	 	 int times;
 	 	 String letter;
 	 	 Scanner nameScan = new Scanner(System.in);
 	 	 
 	 	 // getting the name of the file.
 	 	 System.out.print("Enter the name of the file:  ");
 	 	 fileName = nameScan.nextLine();
 	 	 
 	 	 // getting the letter the file will read
 	 	 System.out.print("Enter the letter for the file to search:  ");
 	 	 letter = nameScan.nextLine();
 	 	 
 	 	 // open the file
 	 	 File file = new File(fileName);
 	 	 Scanner fileScan = new Scanner(file);
 	 	 
 	 	 // reading the file
 	 	 while(fileScan.hasNext()) {
 	 	 	
 	 	 }
 	 	 
 	 	 // close file
 	 	 fileScan.close();
 	 	 
 	 	 // display information
 	 	 System.out.println("The file contains \'" + letter + "\' " + times + " time(s).");
 	 }
 }
