Thread: Change it to array

Hi guys,

let's assum that we have the following program:

import java.io.*;
 
 
class readFile {
public static void main(String[] args) {
String fileName = "store"+ ".txt";
String line;
 
try {
BufferedReader in = new BufferedReader(new FileReader(fileName));
line = in.readLine();
while (line != null) {
 
System.out.println(line);
line = in.readLine();
 
}
 
in.close();
} catch (IOException iox) {
System.out.println("Problem reading " + fileName);
}
}
}

The file have the following inputs:

Jcomputer 12 33
usb 2 34
maps 44 41
ups 23 22

The column are 3 and the line are 4, one string and 2 integers. How can I put them in array (not arraylist)? Any ideas?

Read the file a whole line at a time using something like:

// fileInput is a Scanner object on the file
String[] lineOfData = fileInput.nextLine().split( " " );

(I didn't look at your code, so Scanner is just a suggestion. Use your own approach to read the file a line at a time.)

Then process the array lineOfData as needed. Either use as is, or send it to a constructor to create an object using the data in the array. Do not move the data into 3 parallel arrays.

How can I do that?
Any code examples?
