I need help programming a java program which creates 100 random numbers and writes it to a text file named "Exercise9_19.txt". If the file exists then it justs adds onto it, if the file does not exist, it will create the text file and begin placing the random numbers.

This is what I've done so far... I'm having trouble writing it to the file.

import java.io.*;

import java.util.Random;


public class Question3

{

    public static void main(String[] args) throws IOException

    {

        Random rand = new Random();


        FileWriter outFile = new FileWriter(args[0]);

        PrintWriter out = new PrintWriter(outFile);


        File file = new File("Exercise9_19.txt");


        for( int counter = 0; counter < 100;  counter++ )

        {

            int a = rand.nextInt(); //Makes random numbers fine

            out.println(a); //Need to fix how to take "a" and place it onto the text file

        }


        out.close();

    }

}

You thread will receive enough attention without double posting.
You may want to look at the constructors in this class for starters. FileWriter (Java 2 Platform SE v1.4.2). As is you cannot append.
