Program Plan Intro

Inserting or deleting characters in a string:

  • Library function or modules are provided by the programming languages to perform insert and deletion operations.

Inserting:

The pseudocode library modules that are used to insert the values is :

insert (string1,position,string2)

  • The above function will insert the “string 2” to the “string1” at the “position” specified.
  • “string1” and “string2” is string
  • “Position” is an integer.

Deleting:

The pseudocode library modules that are used to insert the values is

delete (string1,start,end)

  • The above function will delete the strings that are specified from the start to the end.
  • “Start” and “End” is integer that specifies the beginning position and end position.
  • “String” is string.

Example:

The below statement is used to delete the first three characters from the string “city”.

//deletes first three character in city

delete (city, 0, 2)

Explanation:

  • The above function will delete the strings present in the “city” variable that is specified from the position “0” to the position “2”.
  • The above function will delete the first three character of the “city” string.
  • On execution, the “city” will hold “ton” as its value.

Change the following code so that there is always at least one way to get from the left corner to the top right, but the labyrinth is still randomized. The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. Take care that the player and the dragon cannot start off on walls. Also the dragon starts off from a randomly chosen position   public class Labyrinth {    private final int size;    private final Cell[][] grid;     public Labyrinth(int size) {        this.size = size;        this.grid = new Cell[size][size];        generateLabyrinth();    }     private void generateLabyrinth() {        Random rand = new Random();        for (int i = 0; i < size; i++) {            for (int j = 0; j < size; j++) {                // Randomly create walls and paths                grid[i][j] = new Cell(rand.nextBoolean());            }        }        // Ensure start and end are…
Change the following code so that it checks the following 3 conditions: 1. there is no space between each cells (imgs) 2. even if it is resized, the components wouldn't disappear 3. The GameGUI JPanel takes all the JFrame space, so that there shouldn't be extra space appearing in the frame other than the game.   Main():         Labyrinth labyrinth = new Labyrinth(10);         Player player = new Player(9, 0);        Dragon dragon = new Dragon(9, 9);         JFrame frame = new JFrame("Labyrinth Game");        GameGUI gui = new GameGUI(labyrinth, player, dragon);         frame.add(gui);        frame.setSize(600, 600);        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);        frame.setVisible(true);   public class GameGUI extends JPanel {    private final Labyrinth labyrinth;    private final Player player;    private final Dragon dragon; //labyrinth, player, dragon are just public classes     private final ImageIcon playerIcon = new ImageIcon("data/images/player.png");…
Make the following game user friendly with GUI, with some simple graphics. The GUI should be in another seperate class, with some ImageIcon, and Game class should be added into the pane. The following code works as this: The objective of the player is to escape from this labyrinth. The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units.  Cell Class: public class Cell { private boolean isWall; public Cell(boolean isWall) { this.isWall = isWall; } public boolean isWall() { return…
