Air is the block present in otherwise empty space that has no transparent blocks and non-transparent blocks other than the air "block" itself.
Void air[Java Edition only] is used internally for blocks above (Y>255) and below (Y<0) the world, and in unloaded chunks.
In Bedrock Edition, air cannot be obtained in the inventory without editing. In Java Edition, the block is completely unobtainable. Air can only be destroyed or created by the placement or removal of other blocks respectively.
Upon world generation, all otherwise empty spaces are occupied by air. In Java Edition, badlands, abandoned mineshafts, and surface ponds generate cave air, and underground structures generate cave air. Void air is used in place of unloaded chunks and above or below the world's buildable area.[Java Edition only]
Cave air and void air have no special properties; they function the same as normal air, except that cave air is in caves, and void air is in the void.
