Pointer: Pointer will allow the user to indirectly access and manipulate the variable data contents. A pointer variable will hold the address of the data contents. If an asterisk “” operator is present before the variable then that variable is referred as pointer variable. An asterisk “” is also referred as indirection operator is used to dereferences the pointer. Representing array using pointer notation: In general array will have a continuous allocation of memory bytes, to represent the values present in the array it can be represented using its subscript value. So to represent the values using pointer notation with an indirection operator the name of the array plus the subscript representing the value needs to be specified. When we represent only the array name, it will indicate the first element of the array. To represent the next element we need to increment the values by one to find the proceeding elements of the array.

Program Plan Intro

Pointer:

Pointer will allow the user to indirectly access and manipulate the variable data contents. A pointer variable will hold the address of the data contents. If an asterisk “” operator is present before the variable then that variable is referred as pointer variable. An asterisk “” is also referred as indirection operator is used to dereferences the pointer.

Representing array using pointer notation:

In general array will have a continuous allocation of memory bytes, to represent the values present in the array it can be represented using its subscript value.

So to represent the values using pointer notation with an indirection operator the name of the array plus the subscript representing the value needs to be specified.

When we represent only the array name, it will indicate the first element of the array.

To represent the next element we need to increment the values by one to find the proceeding elements of the array.

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…
