| 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 Aor the multiple bounded'T'in'public interface B. | 
| WildcardType | A pattern type, such as the upper bounded wildcard ? extends Closeableor the lower bounded wildcard? super String. | 
| AccessibleObject | AccessibleObjectis the superclass of all member reflection classes
 (Field, Constructor, Method). | 
| Array | 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 | Proxydefines methods for creating dynamic proxy classes and instances. | 
| ReflectPermission | Legacy security code; do not use. | 
| InvocationTargetException | This class provides a wrapper for an exception thrown by a MethodorConstructorinvocation. | 
| 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. |
