Java Write To File - Java Tutorial

In the section of Java Tutorial you will learn 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());   }   } }
