Question

I need to write a java program using these requirements. This is the code I have so far, but Im not sure if it's correct.

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

private class Movie {

public static void main(String[] args) {
// Create LinkedList
LinkedList<String> movies = new LinkedList<>();
// Create HashSet
LinkedHashSet<String> moviesTitle = new LinkedHashSet<>();
// read file name from user
Scanner input = new Scanner(System.in);
String fileName = input.next();
try {
// create an object of Scanner
Scanner file = new Scanner(new File(fileName));
// iterate each line in the file
while (file.hasNextLine()) {
String data = file.nextLine();
movies.add(data);
String[] dataArray = data.split(",");
moviesTitle.add(dataArray[1]);
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}

// format each line
for (String title : moviesTitle) {
// print title
System.out.printf("%-44s", title);
String time = "";
String ratings = "";
for (String movie : movies) {
String[] dataArray = movie.split(",");
if (title.equals(dataArray[1])) {
time = time + dataArray[0] + ",";
ratings = ratings + dataArray[2] + ",";
}

}
// print ratings
System.out.printf("%-10s", ratings.substring(0, ratings.length() - 1));
// print times
System.out.printf("%-25s", time.substring(0, time.length() - 1));
// print vertical bar
System.out.printf("%s", "|");
System.out.println();
}
