Thread: Saving to a text file

I'm not yet fully up to speed with the logic of how to write to a text file.
The program that I am trying to write will save a whole list of chars and their ASCII value (value up to 1000). I want to save the output to a text file as it has unicode so I will be able to see what the symbols are (when eclipse returns the values the symbols show as a ?).
Would any1 be able to suggest to me a link to visit to read up on this or are there any suggestions as to what I should do?

[here is my code]
package testPackage;
import java.io.*;
import java.math.BigDecimal;
import java.nio.charset.Charset;

public class CharListLoopToTxt
{
public static void main(String[] args)
{
for(int i = 0; i<1000; i++)
{
char charLoop;
charLoop = (char) i;
BigDecimal rr = new BigDecimal(charLoop);
Charset charset = Charset.forName("US-ASCII");
String s = "";
try (BufferedWriter writer = Files.newBufferedWriter(file, charset))
{
writer.write(s, 0, s.length());

}

System.out.println(rr +" is the ASCII value for "+ charLoop);

}
}
}

Again I am not yet fully up to speed with the logic of how to write to a text file so just bear that in mind :p

What program are you using to look at the text file? That can determine what you see in its display.
On Windows have you ever created a Unicode text file using Wordpad? Try it and then look at the first bytes of the file. There are some flag bytes there that tell Wordpad about the file's contents.
For example,here is a text file (split into 4 char units) in Unicode format:
FFFE 5400 6800 6900 7300 2000 6900 7300 2000 7500 6E00 6900 6300 6F00 6400 6500 2E00

Wow I did not know of the Files class.. thanks for making me google it They finally made a set of helper methods xD
