So basically the title explains itself. The reason why I am asking this question is due to the fact that I started my Minecraft Xbox 360 world during the December of 2014 and that would mean that my world was created on the TU19 generation. I want to know the Java equivalent so I can figure out the most efficient way to mine in my world, either in the PC chunks or the 360 chunks. Thank you for any help you can provide.
PS. I made my 360 world in 2014 but, I started playing on Java during 2012. Also what I mean by PC chunks or 360 chunks is that I have my original 360 world on my PC because, I converted it to PC so I could play my old world on my PC.
