Code Smells
- There is duplication
- It has long method code smell
- There is no encapsulation because of the exposed state
- Compiler can't mandate all the required parameters are set by the user
- Usage of static state makes it difficult to guess the contract, exposing counter intuitive API
- There are magic numbers
- There is no usage of any access modifier, the state can be mutated by anyone outside the class
- There is no package declaration, missing name space
- Unnecessary comments clutter the code
- The code lacks meaningful variable names, leading to confusion
- The code violates the Single Responsibility Principle, as methods carry out more than one function.
- The code lacks exception handling which can lead to unexpected failures
- There is no proper logging mechanism in place making it difficult to debug
- The code does not follow a consistent naming convention, making it harder to maintain
- Code readability is compromised due to lack of formatting and indentation
- The code is not modular, making it difficult to extend and modify
- There are no unit tests, making it risky to make changes to the code
- The code does not follow the principle of least surprise, leading to confusion and errors
- The code lacks clear separation of concerns, with UI, business logic, and database operations all mixed together
- The code does not use dependency injection, making it less modular and harder to test
- The code has no error handling for edge cases, leaving the system vulnerable to crashes
- The code lacks defensive programming, making it susceptible to bugs and errors
- The code does not adhere to the DRY (Don't Repeat Yourself) principle, leading to redundancy and increased risk of errors
- There is no use of version control, making it hard to keep track of changes and collaborate with others
- The code is not optimized for performance, leading to slow execution times and inefficient resource usage
