JAVA PPROGRAM I have provided the failed test cases and the inputs as a screenshot. Please Modify this program with further modifications as listed below: The program must pass the test case when uploaded to Hypergrade. ALSO, take out the following in the program: System.out.println("Program terminated."); because the test case does not need it. import java.io.*; import java.util.ArrayList; import java.util.Scanner; public class SymmetricalNameMatcher { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); String fileName; do { // Prompt the user to enter a file name or 'QUIT' to exit. System.out.print("Please enter the file name or type QUIT to exit:\n"); fileName = scanner.nextLine(); if (fileName.equalsIgnoreCase("QUIT")) { // If the user types 'QUIT', terminate the program. System.out.println("Program terminated."); break; } File file = new File(fileName); if (!file.exists()) { // If the file doesn't exist, display an error message and continue to the next iteration. System.out.println("File '" + fileName + "' is not found."); continue; } if (file.length() == 0) { // If the file is empty, display an error message and continue to the next iteration.
