'protected' member in 'final' class

Reports protected members in finalclasses.

Since final classes cannot be inherited, marking the method as protected may be confusing. It is better to declare such members as private or package-visible instead.

Example:

record Bar(int a, int b) {
  protected int sum() { 
     return a + b;
  }
}

After the quick-fix is applied:

record Bar(int a, int b) {
  int sum() { 
     return a + b;
  }
}

As shown in the example, a class can be marked as final explicitly or implicitly.
