Why can you tell me?
Maybe Java is different because it allows mods? I dunno and that's a pretty good question.
java and bedrock aren't all that different, it really all comes down to combat, tick speed and hit boxes. bedrock has stationary hitboxes, ie, sneaking shortens you hitbox on java, not bedrock, combat is more skill based on java, where all you have to do is spam click on bedrock, and the tick speed is a little slower on bedrock but thats because of parity issues.
lol i was expecting jokes and not serious comments
