Components of computer: Computer has four major components, they are: • Central processing unit (CPU) • Memory unit • Input devices • Output devices Central Processing Unit (CPU): • CPU plays the key role in a computer by carrying out instructions of a computer program. • It performs all the basic logic, arithmetic, controlling and input/output operations that are specified by the instructions. • The CPU comprises of two units, Arithmetic logic unit (ALU) and control unit (CU). Memory unit: • Once computer program instructions set are transformed into machine code by CPU, the machine code is stored in memory. • Then the CPU fetches the required data and instructions from memory and performs the required operations and then sends the result and next instructions set back to memory. Input devices: • The devices used by the user to feed information to the computer, such as a hard drive, keyboard, or a networking card. • These devices get the data from outside world into the computer in the way that human eyes and ears bring the data to brain. Output devices: • Output devices are used by computer to deliver information to user, such as a monitor, printer, and speaker. • The CPU takes the machine code present in memory and converts it into a format that is mandatory by monitor’s hardware. • Then the monitor’s hardware converts that information into different light intensities so that you see words or pictures.

Program Plan Intro

Components of computer:

Computer has four major components, they are:

• Central processing unit (CPU)

• Memory unit

• Input devices

• Output devices

Central Processing Unit (CPU):

• CPU plays the key role in a computer by carrying out instructions of a computer program.

• It performs all the basic logic, arithmetic, controlling and input/output operations that are specified by the instructions.

• The CPU comprises of two units, Arithmetic logic unit (ALU) and control unit (CU).

Memory unit:

• Once computer program instructions set are transformed into machine code by CPU, the machine code is stored in memory.

• Then the CPU fetches the required data and instructions from memory and performs the required operations and then sends the result and next instructions set back to memory.

Input devices:

• The devices used by the user to feed information to the computer, such as a hard drive, keyboard, or a networking card.

• These devices get the data from outside world into the computer in the way that human eyes and ears bring the data to brain.

Output devices:

• Output devices are used by computer to deliver information to user, such as a monitor, printer, and speaker.

• The CPU takes the machine code present in memory and converts it into a format that is mandatory by monitor’s hardware.

• Then the monitor’s hardware converts that information into different light intensities so that you see words or pictures.

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); } public class GameGUI extends JPanel { private final Labyrinth labyrinth; private final Player player; private final Dragon dragon; private Timer timer; private long…

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…
