What's the best way to write to a file.

[Malith Yapa]

Hiya folks,
Well i was wondering what would be the best way to write out to a text file.
I tried the DataOutputStream and the writeUTF() method( Since none of the other methods are working) But i keep getting two unwanted bites at the beggining of the file. I want the file to be 100% accurate. Got any tips. Why won't the write() methods work? Thanks fellas. Cheers

Hi. If its a simple text file you could do something like...

import java.io.*;
 
 .
 .
 .
 
//Enable file writing
FileWriter file = new FileWriter("Output.txt");
PrintWriter OutputFile = new PrintWriter(file);
 
//print the numbers 1 to 10 in a list in the file
for (int i=1; i<11; i++){
OutputFile.println(i);
}
//print 'End of File' at the end of the file
OutputFile.println("End of File");
 
//close file
close.OutputFile();

Alterntively, you could use a random access file if you want to continually append an existing file...

//Define file
RandomAccessFile outputFile = new RandomAccessFile("Output.rtf", "rw");
 
//Write to file
outputFile.writeBytes("Hello. This is a line in the file, followed by a new line \n");

The API will tell you how to skip to the end of the file etc to manipulate it as well as perform other functions on it, so look there!

Cheers
