Some Java code to Write to a file

How to write java program to write to a file, we will use the class FileWriter and BufferedWriter to write to a file.


Class FileWriter
The FileWriter is a class used for writing character files. The constructors of this class assume that the default character encoding and the default byte-buffer size are acceptable. To specify these values yourself, construct an OutputStreamWriter on a FileOutputStream.

BufferedWriter
The BufferWriter class is used to write text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings.

Here is the code of java program to write text to a file:


import java.io.*;

class FileWrite 
{
public static void main(String args[])
{
  try{
// Create file 
FileWriter fstream = new FileWriter("out.txt");
BufferedWriter out = new BufferedWriter(fstream);
out.write("Hello Java");
//Close the output stream
out.close();
}catch (Exception e){//Catch exception if any
System.err.println("Error: " + e.getMessage());
}
}
}

* this info was found at http://www.roseindia.net/java/beginners/java-write-to-file.shtml, I just found it really nice and simple and want to share it with more people as well.  I am not trying to take the credit for the example.
