Thread: Writing Integers to .txt File; Returning Random Characters Instead of Integers

Hi everybody,

This project is a bit beyond the scope of my class right now, but it's relevant to what we are working on and I was interested so I figured I'd give it a shot. I'm trying to generate 100 random numbers and write them to a .txt file (to be used in another project I've written). Here is my code:

import java.io.*;
import java.util.Random;
 
public class intToFile_main {
 
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
 
		generateFile("C:\\CSEclipseWorkspace\\intToFile\\numbers.txt");
	}
 
private static void generateFile(String fileName) {
 
	try{
 
		FileOutputStream fos = new FileOutputStream(fileName);
		DataOutputStream dos = new DataOutputStream(fos);
 
		Random generator = new Random();
 
		for (int i = 0; i <= 99; i++) {
			int num = generator.nextInt(99) + 1; //generate a random number
			dos.writeInt(num); //write the number to the file
		}
 
		dos.close();
 
		}
 
		catch (IOException e)
		{
			e.printStackTrace();
		} 
 
	}
}

As far as I can tell, it's working, except that rather than displaying numbers, the document reads something like this (it's different every time because of the random number generator):

? > 8 0 S ( " _ Y 9 ( P R P ( @ W % W ? ? ; = C - K > S O 2 a \ L O U " X a
Y $ ( + \ [ 7 # ? & # W c a X ; @ / 5 V / b I : V b G O $ Z 6 2 9 S -

Does anyone have any idea as to what's going on and how I can fix it? Thanks very much!

It worked! Thank you so much!!!
