Im trying ro read a csv file and store it into a 2d array but im getting an error when I run my java code. my csv file contains 69 lines of data Below is my code: import java.util.Scanner; import java.util.Arrays; import java.util.Random; import java.io.File; import java.io.FileNotFoundException; import java.io.FilenameFilter; public class CompLab2 {     public static String [][] getEarthquakeDatabase (String Filename) {     //will read the csv file and convert it to a string 2-d array         String [][] Fileinfo = new String [69][22];         int counter = 0;         File file = new File(Filename);         try {             Scanner scnr = new Scanner(file);             scnr.nextLine(); //skips the label in the first row of the file             while (scnr.hasNextLine()) {  // this while loop will count the number of values in the usgs file                 counter += 1; // increases by one each time a line is read                 scnr.nextLine();             }             while…

What are the Javadoc comments for each class? I am struggling

Consider the GameOfLife class public class GameOfLife { private BooleanProperty[][] cells; public GameOfLife() { cells = new BooleanProperty[10][10]; for (int x = 0; x < 10; x++) { for (int y = 0; y < 10; y++) { cells[x][y] = new SimpleBooleanProperty(); public void ensureAlive(int x, int y) { cells[x][y].set(true); public void ensureDead(int x, int y) { cells[x][y]•set(false); public boolean isAlive(int x, int y) { return cells[x][y]•get(); } a. Identify one code smell in this program. b. Identify and explain the most pertinent (problematic) design smell in this program.
