  - unused import

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

  - Move the variable to comply with JCC.

    According to the Java Code Conventions as defined by Oracle, the members of a class or interface declaration should appear in the following order in the source files:
    Class and instance variables
    Constructors
    Methods

    Issue-ID: VID-579

  - semicolon at the end of this statement.

    In JavaScript, the semicolon (;) is optional as a statement separator, but omitting semicolons can be confusing, and lead to unexpected results because a semicolon is implicitly inserted at the end of each line.
