Readable names are the beginning of collaboration — Learn Java naming systematically.

🧭 Course Features

• Learning the complete process from basic Java naming conventions to domain-based naming

• Team-level style guide document creation with examples

  
  

🧰 Expected Benefits After Taking the Course

• Naming standards became clear, boosting confidence in reviews and collaboration

• Design a naming conventions document that can be applied at the team level

• Improving development efficiency through enhanced code readability and maintainability

💡 This course is for people like this

• Junior Java developers with 1-4 years of experience who frequently receive feedback on naming conventions during code reviews

• Someone who feels difficulty in team collaboration due to hard-to-maintain variable names, function names, and class names

• A team leader who wants to establish clear and consistent naming conventions from the beginning of the project

• Those who want to learn about naming conventions, naming strategies, and renaming

  
  

🤔 Why naming?

"Code is read by humans more often than by machines."

Most developers have grown up focusing on implementing features, but the biggest bottleneck in actual collaboration and maintenance stages is 'hard-to-read code'. The starting point of this issue is precisely 'naming'.

A well-chosen name is better than documentation, and a poorly chosen name becomes the seed of bugs.

This course is designed with a curriculum that includes practical naming strategies for Java developers, along with tool-based automation and refactoring practice.
