Ball hitting finger while backhand

I played table tennis with the techniques given. But the ball hits my finger while playing backhand shot.

Hi Aniket,

First make sure that our finger is staying down low on the rubber.  A good guide is to always be able to feel the writing at the bottom on the rubber.

If you are doing this and it is still hitting your finger, then try to focus on the ball better.  It may just be that you are not watching the ball closely enough.  Focus especially on the contact point and try to make it as simple as possible in the centre of the racket.
