Program Plan Intro

Implementation of specialized templates

Program plan:

Include the required header files in the program.

Define the template class “SimpleVector”:

Declare the required class data members and exception function under “private” access specifier.

Declare the required class member functions and class constructor under “public” access specifier.

Define the specialized template “SimpleVector()” function:

Get the array size and allocate the memory for corresponding array size

Store the c-string values as the array elements.

Define the specialized template copy constructor of the “SimpleVector()” function:

Copy the array size and allocate the memory for corresponding array size

copy the array elements.

Define the specialized template “~SimpleVector” class destructor:

Delete the allocated memory for the array.

Define the specialized template “subError()” function:

Display an error message.

Exit from the program

Define the specialized template function for operator overload for “[]”:

Get the array subscript and check it is in the array range.

If not then call the “subError()” exception function.

Return the subscript.

Define the template class “SearchableVector”, which is derived from the above class template “SimpleVector”:

Declare the required class member functions and class constructor under “public” access specifier.

Define the specialized template copy constructor of the “SearchableVector()” function:

Call the base class copy constructor for copying the array size and allocate the memory for corresponding array size.

Copy the array elements.

Define the specialized template function “findItem()”

Declare the required variables in the function.

Get the element from the function call.

Using while loop

Find the middle element of the array.

Check the middle element is the searching element.

If so, then return the array subscript.

Else, check the middle element is greater than the searching element.

If so, decrease the last index value.

Else, increase the starting index value.

If the element is not found, then return -1 as the array subscript.

Define the main() function:

Create an object for the class “SearchableVector” for c-string type.

Using for loop, display the array on the output screen.

Call the function “findItem()” using c-string element.

Compare the result of the function and display the message according to the condition.

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…
