Im trying to set up lsp mode with java however i get a message that
the lsp server has stopped everytime i try starting it. From searching
the error online, i get that it has something to do with `lsp-java-
workspace` but how do you set in the `.emacs`.  file? I'm thinking its
something like `(setq-default lsp-java-workspace)` but not exactly
sure. Also does it work with any version of java or do i need a
specific version?

The workspace is in `~/.emacs.d/workspace/` by default. Usually, the
issue is that jdtls mess up some of the files and you have to delete
the folder to make it work again.

ah, if i have another folder consisting of java programs, how do i
make my default workspace that folder?

workspace from the jdtls perspective is just a folder that contains
the jdtls cache stuff and related. It is not meant to contain source
code.

okay yeah i tried deleting the folder and restarting emacs, but the
server still stops as soon as it turns on with an error code of 13

Whatever you want, there is no other requirement from language server
perspective
