Call thread from another thread javafx - multithreading

Question

I have been trying to run two tasks on two threads and using their progress to be indicated on progress bar and progress indicator.
First task is copyTask and second is copy file.
The copyTask sends the file object to copyFile for file copy.
But the problem is only a single file gets copied and the file count seems to be correct.
