Adding floor based on image or how to optimize pre-existing method

Hay E :

I'm creating a game with Java for a school project. I currently have a Player class and I am creating the floor he will walk on inside it. Right now, I just made a Clamp method where I add different sections based on the image so he walks on the 'floor'. Eventually, I have platforms that he needs to be able to jump on, but fall if he misses. That code is currently not working and I'm not sure how to go about it. Is there an easier or more efficient way to do the floor? If not, how can I make the platforms work?

I've already tried using a variable at the end of the method to test if it is a platform or not.

The floor needs to work properly in all places where there are no platforms. He just walks on it. Otherwise, if he is landing on a platform he needs to stay on it until that platform ends, then he falls. Or, if he misses a platform then he falls.

Figured it out

    }
}

}
