JAVA.ID.STYLE : Naming Style Violation (Java)

要旨

A class, method, field, or parameter is named in a non-standard way.

Class and method names in Java are traditionally written in a standard way, based on camelization of words. The names of classes start with a capital letter, while the names of fields and methods normally start with a small letter. In particular, a method should not be called as the same class where it is defined, since it might be misunderstood as a constructor. Moreover, a class should not be named as one of its superclasses or superinterfaces, up to the package name, since this can introduce confusion and, potentially, bugs.

                                                   * - class has same simple name as its superclass
                                                   */

  public BadNames(int x) {
      super(x);
  }
}

解決法

Modify the name in order to comply to the standard. In particular, avoid methods or fields starting with a capital letter, unless they are constants.
