Chapter 7, Problem 1RQ
Explanation of Solution
Features of simple network:
- The client computers, server computer, network
operating system software, network interfaces, hub, and a connection medium are the entities of a simple network. - The basic responsible for network operating system software is controlling the network and its functions.
- One client computer is connected to another client computer within the same network.
- Hubs and switches function is sending packets of data to all other linked devices.
- The network helping up web pages to storing data and network operating system.
- The switch has the capability to select a particular destination while the hub sends a packet to all other linked devices.
- The network components links with the connection mediums such as coaxial cables, radio signals or telephone wires.
- The Microsoft Window Server, Linux and Novell Open Enterprise Server are the most commonly used network operating system software...
Explanation of Solution
Principal technologies and trends:
- Client/ Server computing
- Packet switching
- TCP/ IP and Connectivity
Client/ Server computing:
- Client/ Server computing is defined as a distributed computing model where a part of the processing power is placed within cheap client computers and exist in laptops, handled devices or desktops.
- It also allows for computing to departments, factory floors, workgroups and other parts of a business that couldn’t be worked by a centralized architecture.
- The clients are linked to other clients through networks that is controlled by a network server computer.
- It has replaced by centralized mainframe computer.
- The process of the client/ server computing has no longer take place on a central large mainframe computer.
Packet Switching:
- Messages transferring in the internet are divide into fixed size unit of data called packet.
- Messages are divided into packets to increase the performance and reliability of the internet.
- Ιt also improves the effectiveness of the communication line in the internet.
- Packets travel through several routers before it reaches the destination.
- Router is a device that provides a path for the packet to reach the destination...

Add a timer in the following code.
public class GameGUI extends JPanel { private final Labyrinth labyrinth; private final Player player; private final Dragon dragon; private Timer timer; private long elapsedTime;
public GameGUI(Labyrinth labyrinth, Player player, Dragon dragon) { this.labyrinth = labyrinth; this.player = player; this.dragon = dragon; String playerName = JOptionPane.showInputDialog("Enter your name:"); player.setName(playerName); elapsedTime = 0; timer = new Timer(1000, e -> { elapsedTime++; repaint(); }); timer.start();
}
@Override protected void paintComponent(Graphics g) { super.paintComponent(g); int cellSize = Math.min(getWidth() / labyrinth.getSize(), getHeight() / labyrinth.getSize());}
Change the following code so that when player wins the game, the game continues by creating new GameGUI with the same player. However the player's starting position is same, everything else should be reseted.
public static void main(String[] args) { Labyrinth labyrinth = new Labyrinth(10); Player player = new Player(9, 0); Random rand = new Random(); Dragon dragon = new Dragon(rand.nextInt(10), 9); JFrame frame = new JFrame("Labyrinth Game"); GameGUI gui = new GameGUI(labyrinth, player, dragon);
frame.setLayout(new BorderLayout()); frame.setSize(600, 600); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.add(gui, BorderLayout.CENTER); frame.pack(); frame.setResizable(false); frame.setVisible(true); }

Create a menu item which restarts the game. Also add a timer, which counts the elapsed time since the start of the game level.
When the restart is pressed, the restarted game should ask the player' name (in the GameGUI constructor) and set the score of player to 0 (player.setScore(0)), and the timer should restart again. And create a logic so that if the player loses his life (checkGame if the condition is false), then save this number together with his name into two variables. And display two buttons where one quits the game altogether (System.exit(0)) and the other restarts the game.
public class GameGUI extends JPanel { private final Labyrinth labyrinth; private final Player player; private final Dragon dragon;
private final ImageIcon playerIcon = new ImageIcon("data/images/player.png"); private final ImageIcon dragonIcon = new ImageIcon("data/images/dragon.png"); private final ImageIcon wallIcon = new ImageIcon("data/images/wall.png"); private final ImageIcon…
