  - Merge "SonarFix- Remove duplicated import"
  - SonarFix- Remove duplicated import

    The imports part of a file should be handled by the Integrated Development Environment (IDE), not manually by the developer.
    Leaving them in reduces the code's readability, since their presence can be confusing.
