Useful or not, from you.
MCinaBox aarch64_runtime_20200328.tar.xz

were can i find it

That's a useful answer
Without any help

@longjunyu2 can make that aarch64 runtime

The java link is only binary for linux. When I checked the aarch32 runtime pack, I saw that the java (aarch32-runtime-20200320.tar.xz/j2re/) folder contains the aarch32 binary for linux. Although, Android is build on modified linux kernel. But sorry, I don't know much about programming and linux. ;(
