Interfaces

AnnotatedElementThis interface provides reflective access to annotation information. 
GenericArrayTypeThis interface represents an array type with a component type that is either a parameterized type or a type variable. 
GenericDeclarationCommon interface for language constructs that declare type parameters. 
InvocationHandlerImplementors of this interface dispatch methods invoked on proxy instances. 
MemberCommon interface providing access to reflective information on class members. 
ParameterizedTypeThis interface represents a parameterized type such as 'Set<String>'
TypeCommon interface implemented by all Java types. 
TypeVariable<D extends GenericDeclaration>This interface represents a type variables such as 'T' in 'public interface Comparable<T>', the bounded 'T' in 'public interface A<T extends Number>' or the multiple bounded 'T' in 'public interface B<T extends Number & Cloneable>'
WildcardTypeThis interface represents a wildcard type, such as the simple wildcard '?', the upper bounded wildcard '? extends Closeable', the multiple upper bounded wildcard '? extends Closeable & Flushable' or the lower bounded wildcard '? super OutputStream'

Classes

AccessibleObjectAccessibleObject is the superclass of all member reflection classes (Field, Constructor, Method). 
ArrayThis class provides static methods to create and access arrays dynamically. 
Constructor<T>This class represents a constructor. 
FieldThis class represents a field. 
MethodThis class represents a method. 
ModifierThis class provides static methods to decode class and member modifiers. 
ProxyProxy defines methods for creating dynamic proxy classes and instances. 
ReflectPermissionA ReflectPermission object represents a permission to access operations in the reflection layer. 

Exceptions

InvocationTargetExceptionThis class provides a wrapper for an exception thrown by a Method or Constructor invocation. 
MalformedParameterizedTypeExceptionIndicates that a malformed parameterized type has been encountered by a reflective method. 
UndeclaredThrowableExceptionThis class provides a wrapper for an undeclared, checked exception thrown by an InvocationHandler. 

Errors

GenericSignatureFormatErrorIndicates that a malformed signature has been encountered via a reflective method.
