Write Integer to file

Question

Stuck. I've got six integers and I need them to be written to file, each with a new line and for them to overwrite the digits currently held on file. Help appreciated.

Answer 1

I had the same trouble when I started my project (writing stuff to files). But instead of writing new IO methods for every class of mine, I wrote one with a static method. This way it can be called from every class I have. If you want to use it here it is;
import java.io.*;
public class WriteThis
public static String fileName;
public static void WriteIt (String [] whatToWrite)
try
fileName = whatToWrite [0];
String writeOnLine;
FileWriter fw = new FileWriter (fileName);
BufferedWriter bw = new BufferedWriter (fw);
PrintWriter outFile = new PrintWriter (bw);
for (int i = 1; i < whatToWrite.length; i++)
writeOnLine = whatToWrite ["i"];//don't actually use the quotes,
//the whole page kept going to
//italics without them.
outFile.println (writeOnLine);
outFile.close ();
catch (IOException e)
String error = "There was an error";
The way you can use this is to convert your integers into a String array. In the first entry (yourArray [0]) put your filename ("myInts.dat" or whatever you want to call it). It then prints each array index on a new line for your. If you end up using it would you reply to this, just so I know if it is actually useable for everyone.
If you don't want this file saved in the same directory as your classes just pass the path you want it to save to ("C:\Program Files\My Program\here\") and it will save in here\.
To call it all you have to do is something like this:
String [] saving = {
     "myints.dat",
     caption.getText (),
     news.getText ()
WriteThis.WriteIt (saving);
except you will have to convert your integers into strings. Hope this works, and just watch that the formating is right, when I was previewing square braces were working like HTML brackets and parenthesis were working like square brackets.
