Code Smell - Duplicated Code and ExcessiveClassLength

[VictorM-Coder]

Code Smells Issues

During an analysis of the project code with PMD, a series of code smells were identified that can be addressed to enhance the code quality.

Ruleset

For detecting code smells in the project, the team focused on the following code smells as indicated by the professor:

• Excessive Parameter List
• Excessive Class Length
• Excessive Method Length
• God Class
• Data Class
