JAVA PPROGRAM ASAP

Please Modify this program ASAP BECAUSE IT IS HOMEWORK ASSIGNMENT so it passes all the test cases. It does not pass the test cases when I upload it to Hypergrade. Also, for test cases 1-4 it wants only to imput Please enter the file name or type QUIT to exit: then input the file and display the Total number of words. For test cases 5 and 7 it wants to only to input Please enter the file name or type QUIT to exit then input input5.txt and then display File: input5.txt does not exist.\n then display Please enter the file name again or type QUIT to exit:\n then type input1.txt to display the total number of words or type quit to exit the program. For test case 6 it wants only to Please enter the file name again or type QUIT to exit:\n then type quit to exit the porgram.

Because RIGHT NOW IT PASSES 1 OUT OF 7 TEST CASES. I have provided the failed the test cases as a screenshot. The program must pass the test case when uploaded to Hypergrade.

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
String fileName;

while (true) {
System.out.println("Please enter the file name or type QUIT to exit:");
fileName = keyboard.nextLine().trim();

if (fileName.equalsIgnoreCase("QUIT")) {
break; // Exit the loop when "QUIT" is entered
}

File file = new File(fileName);
if (file.exists()) {
int wordCount = countWords(file);
System.out.println("Total number of words: " + wordCount);
} else {
System.out.println("File: " + fileName + " does not exist.");
}
}

keyboard.close();
}

public static int countWords(File file) {
int wordCount = 0;
try {
Scanner inputFile = new Scanner(file);
while (inputFile.hasNext()) {
// Remove leading and trailing whitespaces
String line = inputFile.nextLine().trim();
if (!line.isEmpty()) {
String[] words = line.split("\s+");
wordCount += words.length;
}
}
inputFile.close();
} catch (FileNotFoundException e) {
// File existence already validated
// catch exception for completeness
e.printStackTrace();
}
return wordCount;
}
}
