yep your right !!! ☺

Data keeps on evolving 'Any Big Data company' needs data analytic algorithms to extract valuable insights from huge data dump (in any forms) available in their servers.

Hi nanba (Dear viewer)................

............whether you have noticed the progress bar while copying/downloading the file...... I started dreaming a while about the effort behind the bar which increase our eagerness towards the file wen it ill reach other end of the bar in completion of the download.

Below screen is my thoughts on progress bar.

Below is the small level of impl with help of four letter magic word 'java'  Im sorry for legend viewers for my poor coding standard 

Awaiting for ur valuable rplies to brighten my path towards my goal...... Thanks in advance
