I've made a program that counts, how many words in a text file. And it counts the accurance of a given word in the given text file. The first method that counts the words in the text file is working completely fine, but when the program reaches the method number 2 (frequency) it craches. Can anybody tell me, what I have done wrongly.

When I play the program and it reaches the second method, I get this error "in thread "main" java.util.NoSuchElementException
at java.base/java.util.Scanner.throwFor(Scanner.java:941)
at java.base/java.util.Scanner.next(Scanner.java:1482)
at TextAnalysis22.main(TextAnalysis22.java:19)"

Thanks in advance!

What I have tried:

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

public class TextAnalysis22 {

	public static void main(String[] args) 
			throws FileNotFoundException {
		Scanner console = new Scanner (System.in);
		Scanner data = fileName(console);
		int count = 0;
		while(data.hasNext()) {
			String word = data.next();
			count++;
		}
		System.out.println("The number of words in the given file is " + count);
		
	frequency(data.next(),console.next());		
	}
	
	public static Scanner fileName (Scanner console)
	throws FileNotFoundException{
System.out.println("Enter the path of the file to count the words");
File input = new File(console.nextLine());
while(!input.canRead()) {
	System.out.println("The given file is not found. Try again.");
	System.out.println("Enter the path of the file");
	 input = new File(console.nextLine());
}
	return new Scanner(input);
	}

public static int frequency(String a,String s) {
	  System.out.println("Enter the word to be Searched");
	  int counter = 0;
	  String [] words = null;
	  while(a!=null) {
		  words = a.split(" ");
		  for (String word : words) {
			  if(word.equals(s)) {
				  counter ++;
				  System.out.println("The given word is present for "+counter+ " Times in the file");
			  }
		  }
	  }
	return counter;
	  }
}
