Simple java program to copy files on any OS.

• This is a simple java program to copy files from anywhere to anywhere in the file system and on any operating system.
• Scanner in util package to make inputs dynamic.
• Using the program you just have to enter source of input file with file name and destination where it has to be placed.
• The code calculates the time taken for the processing too.

           long time = endTime - startTime;  
           System.out.println("time taken: " + (double) time / 100 / 60 + " mins");  
      }  
 }
