import java.io.DataInputStream;
      import java.io.FileInputStream;
      import java.io.FileNotFoundException;
      import java.io.IOException;
 
       class ReadDoubleFromFile {
 
      public static void main(String[] args) {
  
      String strFilePath = "E:\\files\\one.txt";
 
      try
 
      {
                  FileInputStream fin = new FileInputStream(strFilePath);
                  DataInputStream din = new DataInputStream(fin);
                  double d = din.readDouble();
                  System.out.println("Double : " + d);
                  din.close();
       }
 
      catch(FileNotFoundException fe)
 
          {
          System.out.println("FileNotFoundException : " + fe);
          }
 
      catch(IOException ioe)
 
      {
      System.out.println("IOException : " + ioe);
      }
 
      }

Nothing stands out at me from the code you posted. Does it work for you? What does it not do that you want it to? What is wrong with it?

You might also consider using the Scanner class (see the API here) instead of the DataInputStream. I think it is a bit easier to use.

Dhan, generally you should post to one forum, then expand to more forums only when/if you don't get satisfactory answers. Then, when you do crosspost Please be Forthright about it, and let everyone involved know about the concurrent conversations that are going on. That way there is more collaboration and less duplication of work.
