Hi Friend,

Try this:

import java.io.*;
class FileWrite 
{
   public static void main(String args[])
  {
      try{
    FileWriter fstream = new FileWriter("out.txt",true);
        BufferedWriter out = new BufferedWriter(fstream);
    out.write("Hello World!");
    out.newLine();
    out.close();
    }catch (Exception e){
      System.err.println("Error: " + e.getMessage());
    }
  }
}

Thanks
