Question

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 (scnr.hasNext()) { // reads through csv file while there is a line of data

String data = scnr.nextLine();

String[] values = data.split(","); // splits the data at the commas

double closingValue = Double.parseDouble(values[4]);

System.out.println(values[4]); // prints the data at element 5

}

scnr.close(); // closes the scanner

} catch (FileNotFoundException e) { //throws exception if file is not found

e.printStackTrace();

}

return Fileinfo;

}

public static void main(String[] args) {

String nameOfFile = "query(2).csv"; //stores the csv file in a string

String [][] earthquakeDatabase = getEarthquakeDatabase (nameOfFile); // creates 2d string array thats equal to method getEarthquakeDatabase

System.out.println("Expected number of rows: 69");

System.out.println("Number of rows from the array: " +earthquakeDatabase);

double [] earthquakeValues = getEarthquakeValues(earthquakeDatabase);

}
