I have minecraft windows 10 edition for the xbox but how do i get it on my computer

Minecraft for the console and Minecraft for Windows 10 are 2 separate purchases. If you have the game for your console, you would need to purchase Minecraft for Windows 10 in order to play it on the PC.

on my computer i made a UI for minecraft i was able to use it in Minecraft: Windows 10 Edition i just need to access global resources in the settings i am unable to access it in my xbox but able to access on my computer

I bought the Windows 10 version of Minecraft by mistake, but the one I wanted was the java edition.

I saw that anyone who buys minecraft java edition is entitled to minecraft Windows 10. Is the reverse also true? Who buys minecraft windows 10 is entitled to minecraft java edition?

If so, how do I access the java edition version at no additional cost?

I have owned Minecraft since 2013 and I have already had the game prior to me factory resetting my computer so I don't understand why I do not have the windows 10 edition.

You would have to have another Xbox. The games do not work cross-platform. There is a Windows 10 edition of Minecraft that you could each play using a computer.
