please help!!!!

We have written the following Movie class below, and we want to be able to use the Collections. sort method to sort an ArrayList. We want to sort by the title instance variable, and we want to break ties by the year instance variable. However, our code doesn't work, and we have no idea why. TASK: Fix the bug(s) in our code. EXAMPLE: After running the following lines of code: ArrayList movies = new ArrayList(); movies.add(new Movie("Good Burger", 1997)); movies.add(new Movie("The Lord of the Rings: The Fellowship of the Ring", 2001)); movies.add(new Movie("Fast Five", 2011)); Collections. sort(movies); for (Movie m : movies) { System.out.println(m); We will print the following: (Fast Five, 2011) (Good Burger, 1997) (The Lord of the Rings: The Fellowship of the Ring, 2001) class Movie { // instance variables private final String title; private final int year; // constructor public Movie(String t, int y) { if(t == null) { this.title = ""; } else { this.title = t; this.year = y; // instance methods public String getTitle() { return this.title; } public int getYear() { return this.year; public String toString() { return "(" + this.title + "," + this.year + ")"; public boolean equals(Object o) { return (o instanceof Movie) && // check if o is a Movie this.year == ((Movie)o).year && // check years for equality this.title.equals(((Movie)o).title); // check titles for equality
