Boolean method name must start with question word

Reports boolean methods whose names do not start with a question word.

Boolean methods that override library methods are ignored by this inspection.

Example:

boolean empty(List<String> list) {
  return list.isEmpty();
}

A quick-fix that renames such methods is available only in the editor.

Configure the inspection:

Use the Boolean method name prefixes list to specify acceptable question words to start boolean method names with.
Use the Ignore methods with 'java.lang.Boolean' return type option to ignore methods with the java.lang.Boolean return type.
Use the Ignore boolean methods in an @interface option to ignore boolean methods in annotation types (@interface).
Use the Ignore methods overriding/implementing a super method to ignore methods the have supers.
