organize imports
stricter usage of final keyword
use collection interfaces

Declarations should use Java collection interfaces such as "List" rather
than specific implementation classes such as "LinkedList".
Methods should not be empty

There are three reasons for a method not to have a method body:
- It is an unintentional omission, and should be fixed.
- It is not yet, or never will be, supported. In this case an
  UnsupportedOperationException should be thrown.
- The method is an intentionally-blank override. In this case a nested
  comment should explain the reason for the blank override.
