Expert Solution & Answer

Chapter 3, Problem 5PE

Explanation of Solution

a.

Program code:

Percentages.java

//import the requird packages

import java.io.;

//define a class Percentages

class Percentages

{

//define a method computePercent()

public static void computePercent(double num1,double num2)

{

//print the percentage values

System.out.println(num1+" is "+((num1/num2)100)+" percent of "+num2+".");

}

//define the main method

public static void main (String[] args)

{

//declare two double values

double num1=2.0,num2=5...

Explanation of Solution

b.

Program code:

Percentage2.java

//import the requird packages

import java.util.Scanner;

import java.io.;

//define a class Percentages

class Percentage2

{

//define a method computePercent()

public static void computePercent(double num1,double num2)

{

//print the percentage values

System.out.println(num1+" is "+((num1/num2)100)+" percent of "+num2+".");

}

//define the main method

public static void main (String[] args)

{

        //declare two double variables

        double num1,num2;

        //create the object of Scanner

        Scanner sc=new Scanner(System.in);

        //prompt the user to enter the values

        System.out.println("Enter two numbers:");

        //scan for the values

num1=sc...

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");…
