      the code runs too slow!! how can it be optimised

      I think Due to recursion it is taking time but in which part of the code it is consuming more time and where to optimize the code.

      Code:
      package scanmove;
import java.io.*;
import java.util.*;

class scanmove
{
    static String destination="F:\\destination\\";
    static Vector <String> vs=new Vector();
    
    public static void main(String args[])
      ...

              The code below has no error at compile time.
              But while executing, it does not show the icon at the left hand top corner of the frame, where a java cup icon is originally shown.

                Hello Friends
                I am having a problem in finding the solution for this Question. Please help me.

                I am having a number say "n". In this case let us consider n=3.

                What i have to do is find first "n" multiples of "n".
                Store the answers somewhere.

                Find again the first "n" multiples of the answers.
                Store the another answers(N1) generated.
                ...

                  replied to How to find the Length of a file in bits
                  in Java
                  I will tell you briefly what i am doing.

                  I am making a program which will check how many duplicate files are there in a folder, and list them.

                  For this i will compare the length of the two files and their extensions.

                  so the file can be of any extension i.e zip, bmp, txt, pdf, etc.

                  If you have any other idea for finding duplicates than please let me know.

                    How to find the Length of a file in bits

                    Hello,
                    For finding the length of a file I use file.length() method. This gives the length in bytes.

                    But I want to find it accurately to the remaining bits. How can I do that.

                      in Java
                      Thanks for your guidance.
                      My problem for copying images is solved.
                      I had used this code for doing that.

                      FileInputStream fis=new FileInputStream (new File("D:/image.bmp"));
                      FileOutputStrea m fos=new FilePutputStrea m(new FIle("D:/copyImage.bmp") );
                      int c;
                      while((c=fis.re ad())!=-1)
                      {
                      fos.write(c);
                      }

                      But one more problem arises. The Speed is very slow....

                              How to add data to JTable from a .txt file.

                              I had seen this code from one of the tutorial from java.com. This code doesnt take any input. But shows what is written in the array.

                              But i want the table to display the data from a .txt file in which i had stored information in this format. Can anyone please modify the codes and explain me.
