I have been given a project called "Assassin" friom my computer science class, and I cannot seem to be able to create the correct methods in order to run this code properly. I am going to paste my current code for this project. If you would like the instructions, please allow me to either email or create another query, as the instructions are on a word document. Please offer assitance if you can, thank you. My current code: import java.io.*; import java.util.*; /**  * Class AssassinMain is the main client program for assassin game management.  * It reads names from a file names.txt, shuffles them, and uses them to start  * the game. The user is asked for the name of the next victim until the game is  * over.  */ public class AssassinMain {     /**      * input file name from which to read data      */     public static final String INPUT_FILENAME = "names.txt";     /**      * true for different results every run; false for predictable results      */     public static final boolean RANDOM = false;     /**      * If not random, use this value to guide the sequence of numbers that will      * be generated by the Random object.      */     public static final int SEED = 42;     public static void main(String[] args) throws FileNotFoundException {         // read names into a Set to eliminate duplicates         File inputFile = new File(INPUT_FILENAME);         if (!inputFile.canRead()) {             System.out.println("Required input file not found; exiting.\n" + inputFile.getAbsolutePath());             System.exit(1);         }         try (Scanner input = new Scanner(inputFile)) {             Set names = new TreeSet<>(String.CASE_INSENSITIVE_ORDER);             while (input.hasNextLine()) {                 String name = input.nextLine().trim().intern();                 if (name.length() > 0) {                     names.add(name);                 }             }             // transfer to an ArrayList, shuffle and build an AssassinManager             ArrayList nameList = new ArrayList<>(names);             Random rand = (RANDOM) ? new Random() : new Random(SEED);             Collections.shuffle(nameList, rand);       AssassinManager manager = new AssassinManager(nameList);  // UNCOMMENT ONCE YOU WRITE THE CONSTRUCTOR             // prompt the user for victims until the game is over             Scanner console = new Scanner(System.in);       while (!manager.isGameOver()) {                           oneKill(console, manager);             }             // report who won             System.out.println("Game was won by " + manager.winner());  // UNCOMMENT ONCE YOU WRITE winner()             System.out.println("Final graveyard is as follows:");             System.out.println(manager.graveyard());      // UNCOMMENT ONCE YOU WRITE graveyard()         }     }     /**      * Handles the details of recording one victim.
