10. Work in Existing Java Packages 

  • Read Source Code of Multiple Java files.

  • Write code in the existing Java file (that already has a jUnit Test-Case), and 

  • Add a new feature without breaking the functionality of existing code.

  • Modify already written jUnit Test Case based on the new requirements.

  • Solve Errors by looking them at Console, log files.
