| public java.lang.Class | asSubclass(java.lang.Class clazz)Casts this Class object to represent a subclass of the class
represented by the specified class object. Checks that that the cast
is valid, and throws a ClassCastException if it is not. If
this method succeeds, it always returns a reference to this class object.
This method is useful when a client needs to "narrow" the type of
a Class object to pass it to an API that restricts the
Class objects that it is willing to accept. A cast would
generate a compile-time warning, as the correctness of the cast
could not be checked at runtime (because generic types are implemented
by erasure).

return (Class<? extends U>) this;
else
throw new ClassCastException(this.toString());

| public boolean | desiredAssertionStatus()Returns the assertion status that would be assigned to this
class if it were to be initialized at the time this method is invoked.
If this class has had its assertion status set, the most recent
setting will be returned; otherwise, if any package default assertion
status pertains to this class, the most recent setting for the most
specific pertinent package default assertion status is returned;
otherwise, if this class is not a system class (i.e., it has a
class loader) its class loader's default assertion status is returned;
otherwise, the system class default assertion status is returned.
Few programmers will have any need for this method; it is provided
for the benefit of the JRE itself. (It allows a class to determine at
the time that it is initialized whether assertions should be enabled.)
Note that this method is not guaranteed to return the actual
assertion status that was (or will be) associated with the specified
class when it was (or will be) initialized.
ClassLoader loader = getClassLoader();
// If the loader is null this is a system class, so ask the VM
if (loader == null)

// If the classloader has been initialized with
// the assertion directives, ask it. Otherwise,
// ask the VM.

| java.util.Map | enumConstantDirectory()Returns a map from simple name to enum constant. This package-private
method is used internally by Enum to implement
public static > T valueOf(Class, String)
efficiently. Note that the map is returned by this method is
created lazily on first use. Typically it won't ever get created.
if (enumConstantDirectory == null) {
T[] universe = getEnumConstantsShared();
if (universe == null)
throw new IllegalArgumentException(
getName() + " is not an enum type");

}
return enumConstantDirectory;
|
| public static java.lang.Class | forName(java.lang.String className)Returns the Class object associated with the class or
interface with the given string name. Invoking this method is
equivalent to:
Class.forName(className, true, currentLoader)
where currentLoader denotes the defining class loader of
the current class.
For example, the following code fragment returns the
runtime Class descriptor for the class named
java.lang.Thread:
Class t = Class.forName("java.lang.Thread")
A call to forName("X") causes the class named
X to be initialized.
return forName0(className, true, ClassLoader.getCallerClassLoader());
|
| public static java.lang.Class | forName(java.lang.String name, boolean initialize, java.lang.ClassLoader loader)Returns the Class object associated with the class or
interface with the given string name, using the given class loader.
Given the fully qualified name for a class or interface (in the same
format returned by getName) this method attempts to
locate, load, and link the class or interface. The specified class
loader is used to load the class or interface. If the parameter
loader is null, the class is loaded through the bootstrap
class loader. The class is initialized only if the
initialize parameter is true and if it has
not been initialized earlier.
If name denotes a primitive type or void, an attempt
will be made to locate a user-defined class in the unnamed package whose
name is name. Therefore, this method cannot be used to
obtain any of the Class objects representing primitive
types or void.
If name denotes an array class, the component type of
the array class is loaded but not initialized.
For example, in an instance method the expression:
Class.forName("Foo")
is equivalent to:
Class.forName("Foo", true, this.getClass().getClassLoader())
Note that this method throws errors related to loading, linking or
initializing as specified in Sections 12.2, 12.3 and 12.4 of The
Java Language Specification.
Note that this method does not check whether the requested class
is accessible to its caller.
If the loader is null, and a security
manager is present, and the caller's class loader is not null, then this
method calls the security manager's checkPermission method
with a RuntimePermission("getClassLoader") permission to
ensure it's ok to access the bootstrap class loader.
if (loader == null) {
SecurityManager sm = System.getSecurityManager();
if (sm != null) {
ClassLoader ccl = ClassLoader.getCallerClassLoader();
if (ccl != null) {

SecurityConstants.GET_CLASSLOADER_PERMISSION);

|
| public java.lang.String | getCanonicalName()Returns the canonical name of the underlying class as
defined by the Java Language Specification. Returns null if
the underlying class does not have a canonical name (i.e., if
it is a local or anonymous class or an array whose component
type does not have a canonical name).
if (isArray()) {

|
| public java.lang.ClassLoader | getClassLoader()Returns the class loader for the class. Some implementations may use
null to represent the bootstrap class loader. This method will return
null in such implementations if this class was loaded by the bootstrap
class loader.
If a security manager is present, and the caller's class loader is
not null and the caller's class loader is not the same as or an ancestor of
the class loader for the class whose class loader is requested, then
this method calls the security manager's checkPermission
method with a RuntimePermission("getClassLoader")
permission to ensure it's ok to access the class loader for the class.
If this object
represents a primitive type or void, null is returned.

the public classes and interfaces that are members of the class
represented by this Class object. This includes public
class and interface members inherited from superclasses and public class
and interface members declared by the class. This method returns an
array of length 0 if this Class object has no public member
classes or interfaces. This method also returns an array of length 0 if
this Class object represents a primitive type, an array
class, or void.

| public java.lang.reflect.Constructor | getConstructor(java.lang.Class parameterTypes)Returns a Constructor object that reflects the specified
public constructor of the class represented by this Class
object. The parameterTypes parameter is an array of
Class objects that identify the constructor's formal
parameter types, in declared order.
If this Class object represents an inner class
declared in a non-static context, the formal parameter types
include the explicit enclosing instance as the first parameter.
The constructor to reflect is the public constructor of the class
represented by this Class object whose formal parameter
types match those specified by parameterTypes.

|
| public java.lang.reflect.Constructor[] | getConstructors()Returns an array containing Constructor objects reflecting
all the public constructors of the class represented by this
Class object. An array of length 0 is returned if the
class has no public constructors, or if the class is an array class, or
if the class reflects a primitive type or void.
Note that while this method returns an array of {@code
Constructor} objects (that is an array of constructors from
this class), the return type of this method is {@code
Constructor[]} and not {@code Constructor[]} as
might be expected. This less informative return type is
necessary since after being returned from this method, the
array could be modified to hold {@code Constructor} objects for
different classes, which would violate the type guarantees of
{@code Constructor[]}.

| public java.lang.reflect.Field[] | getFields()Returns an array containing Field objects reflecting all
the accessible public fields of the class or interface represented by
this Class object. The elements in the array returned are
not sorted and are not in any particular order. This method returns an
array of length 0 if the class or interface has no accessible public
fields, or if it represents an array class, a primitive type, or void.
Specifically, if this Class object represents a class,
this method returns the public fields of this class and of all its
superclasses. If this Class object represents an
interface, this method returns the fields of this interface and of all
its superinterfaces.
The implicit length field for array class is not reflected by this
method. User code should use the methods of class Array to
manipulate arrays.

| public java.lang.reflect.Type[] | getGenericInterfaces()Returns the Types representing the interfaces
directly implemented by the class or interface represented by
this object.
If a superinterface is a parameterized type, the
Type object returned for it must accurately reflect
the actual type parameters used in the source code. The
parameterized type representing each superinterface is created
if it had not been created before. See the declaration of
{@link java.lang.reflect.ParameterizedType ParameterizedType}
for the semantics of the creation process for parameterized
types.
If this object represents a class, the return value is an
array containing objects representing all interfaces
implemented by the class. The order of the interface objects in
the array corresponds to the order of the interface names in
the implements clause of the declaration of the class
represented by this object. In the case of an array class, the
interfaces Cloneable and Serializable are
returned in that order.
If this object represents an interface, the array contains
objects representing all interfaces directly extended by the
interface. The order of the interface objects in the array
corresponds to the order of the interface names in the
extends clause of the declaration of the interface
represented by this object.
If this object represents a class or interface that
implements no interfaces, the method returns an array of length
0.

|
| public native java.lang.Class[] | getInterfaces()Determines the interfaces implemented by the class or interface
represented by this object.
If this object represents a class, the return value is an array
containing objects representing all interfaces implemented by the
class. The order of the interface objects in the array corresponds to
the order of the interface names in the implements clause
of the declaration of the class represented by this object. For
example, given the declaration:
class Shimmer implements FloorWax, DessertTopping { ... }
suppose the value of s is an instance of
Shimmer; the value of the expression:
s.getClass().getInterfaces()[0]
is the Class object that represents interface
FloorWax; and the value of:
s.getClass().getInterfaces()[1]
is the Class object that represents interface
DessertTopping.
If this object represents an interface, the array contains objects
representing all interfaces extended by the interface. The order of the
interface objects in the array corresponds to the order of the interface
names in the extends clause of the declaration of the
interface represented by this object.
If this object represents a class or interface that implements no
interfaces, the method returns an array of length 0.
If this object represents a primitive type or void, the method
returns an array of length 0.
|
| public java.lang.reflect.Method | getMethod(java.lang.String name, java.lang.Class parameterTypes)Returns a Method object that reflects the specified public
member method of the class or interface represented by this
Class object. The name parameter is a
String specifying the simple name of the desired method. The
parameterTypes parameter is an array of Class
objects that identify the method's formal parameter types, in declared
order. If parameterTypes is null, it is
treated as if it were an empty array.
If the name is "{@code };"or "{@code }" a
NoSuchMethodException is raised. Otherwise, the method to
be reflected is determined by the algorithm that follows. Let C be the
class represented by this object:
- C is searched for any matching methods. If no matching
method is found, the algorithm of step 1 is invoked recursively on
the superclass of C.
- If no method was found in step 1 above, the superinterfaces of C
are searched for a matching method. If any such method is found, it
is reflected.
To find a matching method in a class C: If C declares exactly one
public method with the specified name and exactly the same formal
parameter types, that is the method reflected. If more than one such
method is found in C, and one of these methods has a return type that is
more specific than any of the others, that method is reflected;
otherwise one of the methods is chosen arbitrarily.
Note that there may be more than one matching method in a
class because while the Java language forbids a class to
declare multiple methods with the same signature but different
return types, the Java virtual machine does not. This
increased flexibility in the virtual machine can be used to
implement various language features. For example, covariant
returns can be implemented with {@linkplain
java.lang.reflect.Method#isBridge bridge methods}; the bridge
method and the method being overridden would have the same
signature but different return types.

inherited from the Object class. The elements in the array

| public native int | getModifiers()Returns the Java language modifiers for this class or interface, encoded
in an integer. The modifiers consist of the Java Virtual Machine's
constants for public, protected,
private, final, static,
abstract and interface; they should be decoded
using the methods of class Modifier.
If the underlying class is an array class, then its
public, private and protected
modifiers are the same as those of its component type. If this
Class represents a primitive type or void, its
public modifier is always true, and its
protected and private modifiers are always
false. If this object represents an array class, a
primitive type or void, then its final modifier is always
true and its interface modifier is always
false. The values of its other modifiers are not determined
by this specification.
The modifier encodings are defined in The Java Virtual Machine
Specification, table 4.1.
|
| public java.lang.String | getName()Returns the name of the entity (class, interface, array class,
primitive type, or void) represented by this Class object,
as a String.
If this class object represents a reference type that is not an
array type then the binary name of the class is returned, as specified
by the Java Language Specification, Second Edition.
If this class object represents a primitive type or void, then the
name returned is a String equal to the Java language
keyword corresponding to the primitive type or void.
If this class object represents a class of arrays, then the internal
form of the name consists of the name of the element type preceded by
one or more '[' characters representing the depth of the array
nesting. The encoding of element type names is as follows:
| Element Type | | Encoding
|
|---|
| boolean | | Z
| | byte | | B
| | char | | C
| | class or interface
| | Lclassname;
| | double | | D
| | float | | F
| | int | | I
| | long | | J
| | short | | S
|
The class or interface name classname is the binary name of
the class specified above.
Examples:
String.class.getName()
returns "java.lang.String"
byte.class.getName()
returns "byte"
(new Object[3]).getClass().getName()
returns "[Ljava.lang.Object;"

by the class loader of this class.

otherwise it returns false. If this Class
object represents a primitive type, this method returns
true if the specified Class parameter is

raising a ClassCastException. It returns false
otherwise.
Specifically, if this Class object represents a
