Java Program ASAP   ************This program must work in hypergrade and pass all the test cases.**********    The program down below does not work in Hypergrade and does not pass the test cases. Please modify it even more or create a new program so when I upload to hypergrade it passes the test cases.  Thank you!   For Test Case 1 first print out Please enter the file name or type QUIT to exit:\ then you type text1.txtENTER and it displays Stop And Smell The Roses./n there needs to be nothing after that.   For test case 2 first print out Please enter the file name or type QUIT to exit: then you type txt1.txtENTER then it reads out File 'txt1.txt' is not found.\n  Then it didplays Please re-enter the file name or type QUIT to exit:\n after the test file is not found. then you type in text1.txt and it displays stop and smell the roses.\n.   For test case 3 first print out Please enter the file name or type QUIT to exit: then you type text2.txtENTER and it displays A true rebel you are! Everyone was impressed. You'll do well to continue in the same spirit.\n Please explain a bit more in the way of footnotes. From the given text it's not clear what are we reading about.\n and there needs to be nothing after that.    For test case 4 first print out Please enter the file name or type QUIT to exit: then you type somefile.txtENTER and it displays File 'somefile.txt' is not found.\n then it displays Please re-enter the file name or type QUIT to exit:\n then you type anotherbadfile.txtENTER and it dispalys File 'anotherbadfile.txt' is not found.\n then in. repeats Please re-enter the file name or type QUIT to exit:\n and you type quit and it ends the program.    import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; import java.io.InputStreamReader; import java.util.regex.Pattern; import java.util.regex.Matcher; public class WordSeparator {     public static void main(String[] args) {         try (BufferedReader reader = new BufferedReader(new InputStreamReader(System.in))) {             String inputFileName;             boolean fileNotFound;             System.out.print("Please enter the file name or type QUIT to exit:\n");             do{             //while (true) {                 fileNotFound = false; // Reset fileNotFound flag for each iteration                 //System.out.print("Please enter the file name or type QUIT to exit:\n");                 inputFileName = reader.readLine();                 if (inputFileName.equalsIgnoreCase("QUIT")) {                     break;                 }                 try {                     BufferedReader fileReader = new BufferedReader(new FileReader(inputFileName));                     String line;                     StringBuilder result = new StringBuilder();                     while ((line = fileReader.readLine()) != null) {                         // Use regular expressions to split the input into words and punctuation                         Pattern pattern = Pattern.compile("([A-Z][a-z]*|[.!?])");                         Matcher matcher = pattern.matcher(line);                         boolean newSentence = true;                         while (matcher.find()) {                             String token = matcher.group();                             if (newSentence && !token.equals(".")) {                                 result.append(token.substring(0, 1).toUpperCase()).append(token.substring(1));                                 newSentence = false;                             } else {                                 if (token.equals(".") || token.equals("!") || token.equals("?")) {                                     newSentence = true;                                 }                                 result.append(" ").append(token);                             }                         }                     }                     System.out.println(result.toString().trim()); // Remove trailing newline                                         fileReader.close();                     break;                 } catch (IOException e) {                     fileNotFound = true;                     System.out.println("File '" + inputFileName + "' is not found.");                                     System.out.print("Please re-enter the file name or type QUIT to exit:\n");                                 }                 //if (fileNotFound) {                     //System.out.print("Please re-enter the file name or type QUIT to exit:\n");                 //}             }while(true);         } catch (IOException e) {             e.printStackTrace();         }     } }
