Java Reflection [0] - Einführung Bei Edge ist dies jedoch nicht der Fall, und Benutzer müssen die Seite manuell in einen anderen Browser laden. Implementiert die Klasse eine bestimmte Schnittstelle oder erbt sie von einer Basisklasse, lässt sich der Typ der Rückgabe unserer Methode newInstance einschränken. Dann gibt die Maschine beim Lauf alle Klassen aus, die sie lädt. Windows 10 und Java Dieser Artikel gilt für: Du möchtest Java lernen? Klicken Sie auf die Option Einstellungen der Kompatibilitätsansicht. Zwei weitere Dinge werden nach einiger Überlegung deutlich:. Das liegt daran, dass auch in dem Fall, in dem die Klasse mit dem eigenen URLClassLoader bezogen werden soll, die Anfrage trotzdem erst an den System-Klassenlader, dann an den Erweiterungs-Klassenlader und erst ganz zum Schluss an unseren eigenen Klassenlader geht. Java 9 bringt mit Project Jigsaw ein Modulsystem mit. Dies ist die von Oracle derzeit empfohlene Java-Version für Anwender. Erst mal, die Lösung von RalleYTN ist korrekt, so habe ich es auch die ganze Zeit probiert, es hat aber nie funktioniert.

The class loader of this class is used to find the package. Null is returned if no package object was created by the class loader of this class.

Packages have attributes for versions and specifications only if the information was defined in the manifests that accompany the classes, and if the class loader created the package instance with the attributes from the manifest.

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: 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.

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. 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. If this class does not represent an array class this method returns null.

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. In particular, this method returns null if this object represents a primitive type or void.

In particular, this method returns null if the underlying class is a local or anonymous class immediately enclosed by a type declaration, instance initializer or static initializer.

This method returns null if this class or interface is not a member of any other class. If this Class object represents an array class, a primitive type, or void,then this method returns null.

If the underlying class is a top level class this method returns null. Returns an empty string if the underlying class is anonymous.

The simple name of an array is the simple name of the component type with "[]" appended. In particular the simple name of an array whose component type is anonymous is "[]".

Returns null if the underlying class does not have a canonical name i. 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 method denies access to the classes within this class the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of s.

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. See The Java Language Specification , sections 8.

PUBLIC denies access to the fields within this class the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of s.

Array classes return all the public member methods inherited from the Object class. This method returns an array of length 0 if this Class object represents a class or interface that has no public member methods, or if this Class object represents a primitive type or void.

If the class declares multiple public member methods with the same parameter types, they are all included in the returned array. PUBLIC denies access to the methods within this class the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of s.

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.

PUBLIC denies access to the constructors within this class the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of s.

The name parameter is a String specifying the simple name of the desired field. The field to be reflected is determined by the algorithm that follows.

Let C be the class represented by this object: If C declares a public field with the name specified, that is the field to be reflected.

If no field was found in step 1 above, this algorithm is applied recursively to each direct superinterface of C.

The direct superinterfaces are searched in the order they were declared. If no field was found in steps 1 and 2 above, and C has a superclass S, then this algorithm is invoked recursively upon S.

NoSuchFieldException - if a field with the specified name is not found. NullPointerException - if name is null SecurityException - If a security manager, s , is present and any of the following conditions is met: PUBLIC denies access to the field the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of s.

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. Otherwise, the method to be reflected is determined by the algorithm that follows.

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 bridge methods ; the bridge method and the method being overridden would have the same signature but different return types.

PUBLIC denies access to the method the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of s.

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.

NoSuchMethodException - if a matching method is not found. PUBLIC denies access to the constructor the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of s.

This includes public, protected, default package access, and private classes and interfaces declared by the class, but excludes inherited classes and interfaces.

This method returns an array of length 0 if the class declares no classes or interfaces as members, or if this Class object represents a primitive type, an array class, or void.

DECLARED denies access to the declared classes within this class the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of s.

This includes public, protected, default package access, and private fields, but excludes inherited fields. This method returns an array of length 0 if the class or interface declares no fields, or if this Class object represents a primitive type, an array class, or void.

DECLARED denies access to the declared fields within this class the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of s.

This includes public, protected, default package access, and private methods, but excludes inherited methods. This method returns an array of length 0 if the class or interface declares no methods, or if this Class object represents a primitive type, an array class, or void.

See The Java Language Specification , section 8. DECLARED denies access to the declared methods within this class the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of s.

These are public, protected, default package access, and private constructors. If the class has a default constructor, it is included in the returned array.

This method returns an array of length 0 if this Class object represents an interface, a primitive type, an array class, or void. DECLARED denies access to the declared constructors within this class the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of s.

The name parameter is a String that specifies the simple name of the desired field. Note that this method will not reflect the length field of an array class.

DECLARED denies access to the declared field the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of s.

The name parameter is a String that specifies the simple name of the desired method, and the parameterTypes parameter is an array of Class objects that identify the method's formal parameter types, in declared order.

If more than one method with the same parameter types is declared in a class, and one of these methods has a return type that is more specific than any of the others, that method is returned; otherwise one of the methods is chosen arbitrarily.

DECLARED denies access to the declared method the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of s.

The Constructor object for the constructor with the specified parameter list Throws: DECLARED denies access to the declared constructor the caller's class loader is not the same as or an ancestor of the class loader for the current class and invocation of s.

The rules for searching resources associated with a given class are implemented by the defining class loader of the class. This method delegates to this object's class loader.

If this object was loaded by the bootstrap class loader, the method delegates to ClassLoader. Before delegation, an absolute resource name is constructed from the given resource name using this algorithm: Otherwise, the absolute name is of the following form: A InputStream object or null if no resource with this name is found Throws: NullPointerException - If name is null Since: A URL object or null if no resource with this name is found Since: If there is a security manager installed, this method first calls the security manager's checkPermission method with a RuntimePermission "getProtectionDomain" permission to ensure it's ok to get the ProtectionDomain.

SecurityException - if a security manager exists and its checkPermission method doesn't allow getting the ProtectionDomain. 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.

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.

String, boolean , ClassLoader. ClassCastException - if the object is not null and is not assignable to the type T. 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.

ClassCastException - if this Class object does not represent a subclass of the specified class here "subclass" includes the class itself.

AnnotatedElement Returns this element's annotation for the specified type if such an annotation is present, else null. NullPointerException - if the given annotation class is null Since: AnnotatedElement Returns true if an annotation for the specified type is present on this element, else false.

This method is designed primarily for convenient access to marker annotations. AnnotatedElement Returns all annotations present on this element. Returns an array of length zero if this element has no annotations.

The caller of this method is free to modify the returned array; it will have no effect on the arrays returned to other callers.

AnnotatedElement Returns all annotations that are directly present on this element. Unlike the other methods in this interface, this method ignores inherited annotations.

Returns an array of length zero if no annotations are directly present on this element. All annotations directly present on this element Since: That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples.
