[JAVA] Comment installer le langage utilisé dans Ubuntu et comment créer l'environnement

Récemment, j'ai étudié en préparant un environnement avec VM pour chaque langage backend, et récemment je gère la méthode de construction d'environnement avec Gist, mais en quelque sorte vers Qitta. * * Cependant, Gist est écrit en anglais.

environment

• host OS: Windows
• VM: Virtual Box with Vagrant
  • Ubuntu 18.0

** C'est ici que vous créez un environnement virtuel pour CUI ou GUI à l'aide d'Ubuntu. **
