How to save a copy of a file to different location using jfilechooser

Question

hi, this is ravikiran,
In my project there is a situation where when a user clicks on some button, a copy of a file(which is initially in my project folder) must be saved to a location specified by the user.
I have no idea how to do this using JFileChooser.
help me,

JFileChooser lets you choose a file. Once it's done you will have to program the copy function with womething like :
     public void copyToDir(String fileSource,String fileDest) {
          try {
               FileChannel srcChannel = new FileInputStream(fileSource).getChannel();
               FileChannel dstChannel = new FileOutputStream(fileDest).getChannel();
               dstChannel.transferFrom(srcChannel, 0, srcChannel.size());
               srcChannel.close();
               dstChannel.force(true);
               dstChannel.close();
          } catch (IOException e) {
               e.printStackTrace();
     }
