| AnnotatedElement | This interface provides reflective access to annotation information. |
| GenericArrayType | This interface represents an array type with a component type that is either a parameterized type or a type variable. |
| GenericDeclaration | Common interface for language constructs that declare type parameters. |
| InvocationHandler | Implementors of this interface dispatch methods invoked on proxy instances. |
| Member | Common interface providing access to reflective information on class members. |
| ParameterizedType | This interface represents a parameterized type such as 'Set<String>'. |
| Type | Common interface implemented by all Java types. |
| TypeVariable<D extends GenericDeclaration> | This interface represents a type variables such as 'T' in 'public interface Comparable, the bounded 'T' in 'public interface A or the multiple bounded 'T' in 'public interface B. |
| WildcardType | A pattern type, such as the upper bounded wildcard ? extends Closeable or the lower bounded wildcard ? super String. |
| AccessibleObject | AccessibleObject is the superclass of all member reflection classes
(Field, Constructor, Method). |
| Array | This class provides static methods to create and access arrays dynamically. |
| Constructor<T> | This class represents a constructor. |
| Field | This class represents a field. |
| Method | This class represents a method. |
| Modifier | This class provides static methods to decode class and member modifiers. |
| Proxy | Proxy defines methods for creating dynamic proxy classes and instances. |
| ReflectPermission | A ReflectPermission object represents a permission to access
operations in the reflection layer. |
| InvocationTargetException | This class provides a wrapper for an exception thrown by a Method or
Constructor invocation. |
| MalformedParameterizedTypeException | Indicates that a malformed parameterized type has been encountered by a reflective method. |
| UndeclaredThrowableException | This class provides a wrapper for an undeclared, checked exception thrown by an InvocationHandler. |
| GenericSignatureFormatError | Indicates that a malformed signature has been encountered via a reflective method. |
