I was hit by opponent ball without bouncing , on the full ,while I was standing outside the court behind the baseline.who takes the point?

No one gets the point, it is foul.

Tick

Your opponent gets the point. The ball is never out until it hits the ground. If you or your doubles partner are hit on the full by an opponents serve then the server gets the point. The ball must hit the ground before it can be called out.

Agreed. In this case, you are an extension of your raquet, so the point goes to your opponent
