class writeData
     public String getName()
                    String name=null;
     try
          char c;
          StringBuffer bf=new StringBuffer();
          System.out.print("Enter the File Name:- ");
          while((c=(char)System.in.read())!='\n')
               bf.append(c);
          name=bf.toString();
          catch(Exception e)
          System.out.println("Error is:-"+e);
          return name;
public void wfile(String name1)
          try
          String path ="D:/fname.txt";
          boolean append = true;
          FileWriter fw=new FileWriter(path); // its not working....
          //FileWriter fw=new FileWriter("D:/fname.txt");
          catch(Exception e)
               System.out.println("Error is :- "+e);
public class bravo
     public static void main(String args[])
          writeData wd = new writeData();
          String n = wd.getName();
          wd.wfile(n);
}
