Known Indirect Subclasses
| Class<T> |
Instances of the class Class represent classes and
interfaces in a running Java application. |
| Constructor<T> |
Constructor provides information about, and access to, a single
constructor for a class. |
| Executable |
A shared superclass for the common functionality of Method
and Constructor. |
| Method |
A Method provides information about, and access to, a single method
on a class or interface. |
|
A common interface for all entities that declare type variables.
