debug_java.lua

-- Purpose: Debug a single Java class from within LazyVim
-- Overview of steps:
--   1. Update ~/.config/nvim/lua/config/lazy.lua to enable the 'Java Extra'
--   2. Add new plugin config at ~/.config/nvim/plugins/debug_java.lua
--   3. Test: Add break point, hit <leader>dA, Observe debugging in action.
-- Notes:
--   1. Works for a single Java file, larger projects likely will need other steps or configuration
--   2. Solution was found on Reddit, see reference 1.
