Tools and first-week setup

The tools a Java Full Stack Development intern uses and how to set up your workspace in week one.

These are the main tools for Java Full Stack Development tasks. You do not need all of them on day one; the Level 1 tasks tell you when to install each one.

  • Java 21
  • Spring Boot
  • Spring Data JPA
  • MySQL
  • React
  • Docker

Set up your workspace

  • Create a free GitHub account if you do not have one, with a professional username, and set up your LinkedIn profile: every task is submitted with a LinkedIn post.
  • Create one repository for the internship, for example java-full-stack-development-internship, with a README that says who you are and what the repo holds.
  • Keep one folder per task, named with the task number and title, so mentors find your work quickly.
  • Commit small changes every day with clear messages. Your daily work report uses these commits as proof.
  • Never commit passwords, API keys or personal data. Put secrets in a .env file and add it to .gitignore.
