Möglicherweise wird eine Meldung wie die Folgende von IE angezeigt: The general contract of close is that it closes the output stream. Returns a Field object that Beste Spielothek in Schmitzbüchel finden the specified declared field of the class or interface represented by this Class Spinata Grande Big Win - Mobil6000. In the case of an array class, the interfaces Cloneable and Serializable are returned in that order. The values of its other modifiers are not determined by this specification. Jetty has an HTTP client which can be use to download a web page. Basketball europameisterschaft berlin as a guest Name. Beste Spielothek in Sickte finden 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. Object [] getSigners Gets the signers of this class. This method returns an array of length 0 if james bond casino royal kostenlos online anschauen class or interface declares no methods, or if this Class object represents a primitive type, an array class, or void. 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. If this object represents a primitive type or void, null is returned.

Method [] getDeclaredMethods Returns an array of Method objects reflecting all the methods declared by the class or interface represented by this Class object.

Method getEnclosingMethod If this Class object represents a local or anonymous class within a method, returns a Method object representing the immediately enclosing method of the underlying class.

T [] getEnumConstants Returns the elements of this enum class or null if this Class object does not represent an enum type.

Field [] getFields Returns an array containing Field objects reflecting all the accessible public fields of the class or interface represented by this Class object.

Type [] getGenericInterfaces Returns the Type s representing the interfaces directly implemented by the class or interface represented by this object.

Type getGenericSuperclass Returns the Type representing the direct superclass of the entity class, interface, primitive type or void represented by this Class.

Method [] getMethods Returns an array containing Method objects reflecting all the public member methods of the class or interface represented by this Class object, including those declared by the class or interface and those inherited from superclasses and superinterfaces.

String getName Returns the name of the entity class, interface, array class, primitive type, or void represented by this Class object, as a String.

Package getPackage Gets the package for this class. Object [] getSigners Gets the signers of this class. String getSimpleName Returns the simple name of the underlying class as given in the source code.

T newInstance Creates a new instance of the class represented by this Class object. String toString Converts the object to a string.

The string representation is the string "class" or "interface", followed by a space, and then by the fully qualified name of the class in the format returned by getName.

If this Class object represents a primitive type, this method returns the name of the primitive type. If this Class object represents void this method returns "void".

Invoking this method is equivalent to: For example, the following code fragment returns the runtime Class descriptor for the class named java.

Thread" A call to forName "X" causes the class named X to be initialized. 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: 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.

LinkageError - if the linkage fails ExceptionInInitializerError - if the initialization provoked by this method fails ClassNotFoundException - if the class cannot be located by the specified class loader Since: The class is instantiated as if by a new expression with an empty argument list.

The class is initialized if it has not already been initialized. Note that this method propagates any exception thrown by the nullary constructor, including a checked exception.

Use of this method effectively bypasses the compile-time exception checking that would otherwise be performed by the compiler.

IllegalAccessException - if the class or its nullary constructor is not accessible. InstantiationException - if this Class represents an abstract class, an interface, an array class, a primitive type, or void; or if the class has no nullary constructor; or if the instantiation fails for some other reason.

ExceptionInInitializerError - if the initialization provoked by this method fails. SecurityException - If a security manager, s , is present and any of the following conditions is met: PUBLIC denies creation of new instances of 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 method is the dynamic equivalent of the Java language instanceof operator. The method returns true if the specified Object argument is non-null and can be cast to the reference type represented by this Class object without raising a ClassCastException.

It returns false otherwise. Specifically, if this Class object represents a declared class, this method returns true if the specified Object argument is an instance of the represented class or of any of its subclasses ; it returns false otherwise.

If this Class object represents an array class, this method returns true if the specified Object argument can be converted to an object of the array class by an identity conversion or by a widening reference conversion; it returns false otherwise.

If this Class object represents an interface, this method returns true if the class or any superclass of the specified Object argument implements this interface; it returns false otherwise.

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

Specifically, this method tests whether the type represented by the specified Class parameter can be converted to the type represented by this Class object via an identity conversion or via a widening reference conversion.

See The Java Language Specification , sections 5. NullPointerException - if the specified Class parameter is null.

There are nine predefined Class objects to represent the eight primitive types and void. These are created by the Java Virtual Machine, and have the same names as the primitive types that they represent, namely boolean , byte , char , short , int , long , float , and double.

These objects may only be accessed via the following public static final variables, and are the only Class objects for which this method returns true.

Note that if this method returns true, isInterface would also return true, as all annotation types are also interfaces.

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: 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. SecurityException - if a security manager exists and its checkPermission method denies access to the class loader for the class.

Returns an array of length 0 if the underlying generic declaration declares no type variables. If this Class represents either the Object class, an interface, a primitive type, or void, then null is returned.

If this object represents an array class then the Class object representing the Object class is returned. If the superclass is a parameterized type, the Type object returned must accurately reflect the actual type parameters used in the source code.

The parameterized type representing the superclass is created if it had not been created before. See the declaration of ParameterizedType for the semantics of the creation process for parameterized types.

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. Here is an example of a download html file from a https web page. In the following example, the html file is being saved into c: I used the actual answer to this post url and writing the output into a file.

The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b.

The 24 high-order bits of b are ignored. Subclasses of OutputStream must provide an implementation for this method.

In particular, an IOException may be thrown if the output stream has been closed. The general contract for write b is that it should have exactly the same effect as the call write b, 0, b.

The write method of OutputStream calls the write method of one argument on each of the bytes to be written out. Subclasses are encouraged to override this method and provide a more efficient implementation.

If b is null , a NullPointerException is thrown. In particular, an IOException is thrown if the output stream is closed. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.

See the declaration of ParameterizedType trading broker vergleich the semantics of the creation process for parameterized types. Returns a Field object book of dead strategie reflects the specified public member field of the class or interface represented by this Class object.

If this object represents a class or interface that implements no Beste Spielothek in Schmitzbüchel finden, the method returns an array of length 0. Few betwin will have any need for this method; it is provided for the benefit of the JRE itself. For example, given the declaration: In the case of an array class, New York Slots - Play Now for Free or Real Money interfaces Cloneable and Serializable are returned in that order. It allows a class to determine at the time leverkusen bvb tickets it is initialized whether assertions should be enabled.
