JAVA help Need help with this part of the code: If the File exists, read from the File. Capitalize the first letter in the file and capitalize the 1st letter after every period and correct the spacing by removing any duplicate spaces so that there is only 1 space between words. Write the modified output to a file named HomeworkOutput6-2.txt

If you have any doubts, please give me comment...

import java.io.*;

import java.util.*;

public class ReadAndEditFile {

public static void main(String[] args) {

String fileName;

Scanner in = new Scanner(System.in);

System.out.print("What is the name of your file? ");

fileName = in.next();

boolean fileExists = true;

Scanner fileIn = null;

do {

try {

fileIn = new Scanner(new File(fileName));

fileExists = true;

} catch (FileNotFoundException e) {

System.out.println("File Not Found " + fileName);

fileExists = false;

System.out.print("Reenter name of file: ");

fileName = in.next();

}

} while (!fileExists);

try {

PrintWriter pw = new PrintWriter(new File("HomeworkOutput6-2.txt"));

while (fileIn.hasNextLine()) {

String line = fileIn.nextLine();

String words[] = line.split(" ");

String newStr = ((words[0].charAt(0) + "").toUpperCase()) + words[0].substring(1).toLowerCase();

for (int i = 1; i < words.length; i++){

newStr += " " + words[i];

if(words[i].indexOf(".")!=-1 && (i+1)<words.length)

words[i+1] = ((words[i+1].charAt(0) + "").toUpperCase()) + words[i+1].substring(1).toLowerCase();

}

pw.println(newStr);

}

pw.close();

} catch (FileNotFoundException e) {

System.out.println("Unable to open file");

}

}

}
