Um I haven't tried this but try:

PrintWriter fout = new PrintWriter(new FileWriter("OUT.txt"));
for (int index=0;index<arlNums.size();index++) {
fout.println(arlNums.get(index));
}

Yeah just tried it, and it's working great.

import java.util.*;
import java.io.*;
public class al {
    public static void main(String[] args) throws IOException {
        Scanner fin = new Scanner(new FileReader("data.txt"));
        PrintWriter fout = new PrintWriter(new FileWriter("OUT.txt"));
        ArrayList alnNums = new ArrayList<Integer>();
        
        while (fin.hasNextInt()) {
            alnNums.add(fin.nextInt());
        }

        for (int index=0;index<alnNums.size();index++) {
            fout.println(alnNums.get(index));
        }

        fout.close();
        fin.close();
    }

}

That does work. Hope it helps.
