How to testfor and set blocks relative to a block

[Durtle02]

Hi again, I'm wondering how to test if surrounding blocks are not "air" or "BlockA" then set them to "BlockA" in a random time interval.

 

EDIT: I saw a previous post. I'm looking for a way with coords.

It is surprising how much of this thread is relevant.

I've seen people doing it with xyz being variables and they could test using those. Does that require a specific handmade script of is it prebuilt in?

world.getBlockState(new BlockPos(x, y, z)).getBlock() == block

Thanks

Also how do I update at a random rate?
