Implement the Plates class buildMap function so that it populates the HashMap with the state abbreviations as keys and the counts of how many each appear in the file as values. Sometimes, the parking attendant will add special notation to help her remember something about a specific entry. There are just non alphabetic characters that she adds to the state - your program should ignore these characters so that an entry like NY* still counts toward the NY plate count. She is also very inconsistent with how she enters the plates. Sometimes she uses upper case, sometimes lowercase, and sometimes she even uses a mix. Be sure to account for this in your program. Only add information for plates in New England (Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, and Connecticut). Plates.java import java.util.Arrays; import java.util.HashMap; import java.util.HashSet; import java.util.Map; import java.util.Set; public class Plates { private Map<String, Integer> plateMap; private Set<String> validStates; public Plates() { plateMap = new HashMap<>(); validStates = new HashSet<>(Arrays.asList("CT", "MA", "ME", "NY", "RI", "VT")); } public void buildMap(String filePath) { // Implement me... } public void printCounts() { System.out.println("Number of Plates: " + plateMap.keySet().size()); for (Map.Entry<String, Integer> entry : plateMap.entrySet()) System.out.printf("%s -> %s%n", entry.getKey(), entry.getValue()); } } Main.java public class Main { public static void main(String[] args) { Plates main = new Plates(); main.buildMap(); main.printCounts(); /* * The output should be: * * Number of Plates: 6 * MA -> 2 * ME -> 3 * CT -> 1 * NY -> 5 * RI -> 5 * VT -> 1 */ } } plates.txt vt ma ME nY, NY me CA nE Ct NJ- WA MA ri me ny ny NY *Nj billnye mAr $RI% Ri ir RI .

Implement these classes and a interface in 3 Java programs: Class 1: Track(String trackName, String[] musicians, int durSecs) - The constructor creates a track object. String gettrackName() - Accessor for the track name String[] getMusicians() - Accessor for the list of musicians int getDurSecs() - Accessor for the duration of the track Class 2: InfTracklist(String trackName) -- Create a track list with the given name String gettrackName() - Return the name of the track list int num() -- Return the number of tracks in the track list Track start() - Return the current track, and then move the current track to the next item in the list (plays current track, then moves to the next track) void add(Track track) - Add a new track to be the next track The track list works with an iterator interface called TrackIterator, so that the user can move forward or backwards through the list without changing the currently playing track. The track list exports these public methods that use an iterator. TrackIterator iterator() - This returns an instance of a TrackIterator starting from the current track. void reset(TrackIterator it) - Set playback to start from the track pointed to by the track iterator void remove(TrackIterator it) - Remove the track pointed to by the iterator. If the current track is pointed to by the iterator, set it to the next track, or null if there are no more tracks. TrackIterator: The TrackIterator interface represents an iterator that allows you to move through the list from the current point. The Zune uses this to allow you to move through tracks forwards and backwards. The iterator's abstract methods are: Track current() -- Get the current track that the iterator is pointing to void next() - Advance the iteration void previous() - Move backwards in the iteration Since the iterator is defined as an interface in TrackIterator.java, you have to provide a concrete implementation of this interface for your iterator. Provide your own concrete class that implements TrackIterator. Create your iterator implementation as a (non-public) class inside InfTracklist.java. Call it anything you want. Stylistically, a lot of people append "Impl" to their classes that implement an interface, so you could call it TrackIteratorImpl, for example. Casting is the process of converting one type to another. In the program, the InfTracklist.remove(TrackIterator it) method takes a TrackIterator as an argument. That's great, except that TrackIterator is an interface. You really need the class that implements the TrackIterator, which is TrackIteratorImpl. However the argument is of type TrackIterator. So how do we change a TrackIterator to a TrackIteratorImpl? Inside the remove function, we can cast it, like this: TrackIteratorImpl itImpl = (TrackIteratorImpl) it Now we have a itImpl variable that we can use. .

Implement the following in my java program which is written under the requirements: When a new member joins, the server will check if it is the first member. If it is, the member will be informed and become the coordinator. If not, the member will request details of existing members from the server and receive everyone's IDs, IP addresses, and ports, including the current group coordinator. The new member will then contact everyone through the server to let them know that they can update their set of members to include the new member. If some members do not respond, the new member will inform the server, and the server will inform other members to update their local list of existing members. If the coordinator does not respond, any new member will become the coordinator. The coordinator will maintain the state of group members by checking periodically how many of them are not responding and inform active members about it so they can update their state of members. Implement a messaging system for members to send private or broadcast messages to every other member through the server. Print out messages sent to and by the members. Allow the program to run either automatically or manually. In the former case, simulate the task automatically without accepting any input parameters from users. In the latter case, the program will require user input to simulate the task. My java program code: import java.awt.BorderLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.io.PrintWriter; import java.net.ServerSocket; import java.net.Socket; import java.util.ArrayList; import java.util.List; import java.util.UUID; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JOptionPane; import javax.swing.JPanel; import javax.swing.JTextField; public class MemberServer { private JFrame frame; private JTextField idField; private JTextField ipField; private JTextField portField; private JLabel statusLabel; private static ServerSocket serverSocket; private boolean isRunning; // Frame 1 public MemberServer() { frame = new JFrame("Member Server"); frame.setLayout(new BorderLayout()); JPanel panel = new JPanel(); panel.setLayout(null); JLabel idLabel = new JLabel("ID:"); idLabel.setBounds(10, 10, 100, 25); panel.add(idLabel); idField = new JTextField(); idField.setBounds(120, 10, 165, 25); panel.add(idField); JLabel ipLabel = new JLabel("IP Address:"); ipLabel.setBounds(10, 40, 100, 25); panel.add(ipLabel); ipField = new JTextField(); ipField.setBounds(120, 40, 165, 25); panel.add(ipField); JLabel portLabel = new JLabel("Port:"); portLabel.setBounds(10, 70, 100, 25); panel.add(portLabel); portField = new JTextField(); portField.setBounds(120, 70, 165, 25); panel.add(portField); // Start Button JButton startButton = new JButton("Start Server"); startButton.setBounds(10, 100, 125, 25); startButt.

One group of participants listens to a song of my choosing while they run, and another group of participants listens to no music while they run. (4 points) What is my independent variable? What is my dependent variable? What kind of statistical analysis would I use to determine the difference in running speed between these two groups? What is the null hypothesis in this scenario? .

Imagine that a mutant strain of Drosophila undergoes crossing over at half the normal rate. How would a genetic map prepared for this mutant differ from a genetic map prepared for a normal (wild type) fly?The order of genes would be the same in both strains, but the distances measured between genes in the mutant would be half those of the wild type.The distances between genes would be the same in both strains, but gene order in the mutant strain would be a mirror image of the gene order of the wild type.The maps would not differ.Both gene order and distance would be scrambled in the mutant relative to the wild type. .
