This is java problem

this is the code:

Step 1: Complete the implementation of the movie class. Make sure you fill in the class and method header comments and declarations where information is missing. First, read the entire Movie.java file. After reading the file, add code to complete the implementation of the tostring), equals), and compareTo () methods. Before you can search a List for an item, you must sort the List by calling the sort ) method of the Collections class. This method will call the compareTo method of each item that is present in the List. Sample code that uses sort 0 to sort a list is given below List myList new ArrayListo myList.add ( new Person (. ) ), Collectons.sort (myList In order to search a List to find a particular object you must call the binarysearch ) method of the Collections class. This method takes as a parameter an object (called the key) that represents the object we are searching for. If binarysearch ) finds the key in the list, it will return the index to the item in the list that matches the key, otherwise it will return a negative integer (we talked about how this negative integer is computed in class). Sample code that uses binarysearch ) to search for an item in a list is given below Person key = new Person( ); Person result int index; index = collections.binarysearch ( myList, key ), if( index> index "in the list." else t list!" result = List.get( index ); system.out.println( result.tostring) + " resides at index "+ System.out.println( key.tostring () was not found in the
