I accidently deleted my minecraft world...

F in the chat

If you did in fact delete your world, then no, there is no way to recover it.

But its my world in Minecraft as deleted and i deleted the game and re instaled but the world Don't came

If you have deleted a world, then there is no way to get it back.

I had this problem before. I would try to delete Minecraft and reinstalled it. If you just delete minecraft it won't delete your world. There's a separate box where it shows your save data, don't delete that. Is it only for one of your worlds, because I
only had one world that would crash. Hope this helps man.

Sorry to say but you can't get the world back. When you delete a world in minecraft it stays deleted.
