in java code: Simulate a forest fire. Complete the ForestFireSimulation class by implementing the nextStep() method that will perform the next step in the simulation. At each step, the fuel should be updated. This is done by decrementing the available fuel for a tree by 1. If there is no more fuel available, then the tree should be replaced with ash. Next, trees that are on fire can spread a spark to neighboring trees with a probability of spreadProb. Trees that have a spark should then be turned into a fire in the same step. The final action that needs to be completed in a step is setting new fires. Any tree can be ignited by lightning with a probability of lightningStrikeProb. getForestDensity, getSizeofFire and getFuelLevel should also be implemented in a reasonable fashion. import java.util.Random; public class ForestFireSimulation { public static final char TREE = '8'; public static final char SPARK = '.'; public static final char FIRE = '*'; public static final char ASH = '^'; public static void main(String[] args) { ForestFireSimulation ffSimulation = new ForestFireSimulation(15, .45, .01, .4); for(int i = 0; i < 100; i++) { ffSimulation.nextStep(); ffSimulation.printForest(); System.out.printf("Forest Density: %.2f\n", ffSimulation.getForestDensity()); System.out.printf("Fuel: %d\n", ffSimulation.getFuelLevel()); System.out.printf("Fire Size: %.2f\n", ffSimulation.getSizeOfFire()); System.out.println("--------------------------------\n"); } } char[][] forest; int[][] fuel; double lightningStrikeProb; double spreadProb; Random r; public ForestFireSimulation(int N, double forestDensity, double lightningStrikeProb, double spreadProb) { forest = new char[N][N]; fuel = new int[N][N]; this.lightningStrikeProb = lightningStrikeProb; this.spreadProb = spreadProb; r = new Random(); for(int i = 0; i < N; i++) { for(int j = 0; j < N; j++) { if(r.nextDouble() < forestDensity) { forest[i][j] = TREE; fuel[i][j] = r.nextInt(5) + 1; } else { forest[i][j] = ' '; fuel[i][j] = 0; } } } } public void printForest() { System.out.print(" "); for(int i = 0; i < forest.length; i++) {System.out.print("--");} System.out.println(); for(int i = 0; i < forest.length; i++) { System.out.print("|"); for(int j = 0; j < forest[i].length; j++) { System.out.print(forest[i][j] + " "); } System.out.println("|"); } System.out.print(" "); for(int i = 0; i < forest.length; i++) {System.out.print("--");} System.out.println(); } // help to implement this method public void nextStep() { // Update fuel // Spread sparks // Change sparks to fire // New fires } public double getForestDensity() { return 0; } public double getSizeOfFire() { return 0; } public int getFuelLevel() { return 0; } }
