How to fetch data from database after 2 seconds on a jsp page

Currently I'm working on a college web project. My application/web page is sports application/web page, so I wanted to fetch fresh score from database or an external API after every 2 seconds on my jsp page so please provide me a solution in which I do not have to refresh my page (if it is possible) and fetch latest score.

I'm really not getting what to do. Please help me out.
