  Modifier and Type
  Method
  Description
  `Type[]`

  `interface`
  `ParameterizedType`
  ParameterizedType represents a parameterized type such as `Collection<String>`.
  `interface`
  `TypeVariable<D extends GenericDeclaration>`
  TypeVariable is the common superinterface for type variables of kinds.
  `interface`
  `WildcardType`
  WildcardType represents a wildcard type expression, such as `?`, `? extends Number`, or `? super Integer`.
