![]() Returns: a newly allocated instance of the class represented by this The Constructor.newInstance method avoids this problem by wrappingĪny exception thrown by the constructor in a (checked) InvocationTargetException. This method effectively bypasses the compile-time exceptionĬhecking that would otherwise be performed by the compiler. Nullary constructor, including a checked exception. Note that this method propagates any exception thrown by the The class is instantiated as if by a newĮxpression with an empty argument list. The specified class loader Since: 1.2 See Also: forName(String),Ĭreates a new instance of the class represented by this Class loader - class loader from which the class must be loaded Returns: class object representing the desired class Throws: LinkageError - if the linkage fails ExceptionInInitializerError - if the initialization provokedīy this method fails ClassNotFoundException - if the class cannot be located by See Section 12.4 of The Java Language Specification. Parameters: name - fully qualified name of the desired class initialize - if true the class will be initialized. With a RuntimePermission("getClassLoader") permission toĮnsure it's ok to access the bootstrap class loader. Method calls the security manager's checkPermission method Manager is present, and the caller's class loader is not null, then this Note that this method does not check whether the requested class ![]() Initializing as specified in Sections 12.2, 12.3 and 12.4 of The Note that this method throws errors related to loading, linking or The array class is loaded but not initialized.įor example, in an instance method the expression:Ĭlass.forName("Foo", true, this.getClass().getClassLoader()) If name denotes an array class, the component type of Obtain any of the Class objects representing primitive Will be made to locate a user-defined class in the unnamed package whose If name denotes a primitive type or void, an attempt Initialize parameter is true and if it has Loader is null, the class is loaded through the bootstrapĬlass loader. Loader is used to load the class or interface. Locate, load, and link the class or interface. Given the fully qualified name for a class or interface (in the sameįormat returned by getName) this method attempts to Interface with the given string name, using the given class loader. ![]() Returns the Class object associated with the class or forName public static Class forName( String className).Information about modifiers and type parameters Since: 1.8 Returns: a string describing this Class, including Originating source code or illegal on the originating sourceĬode may be present. Of a type is being generated, modifiers not present on the Note that since information about the runtime representation Separate any modifiers from the kind of type. The string is formatted as a list of type modifiers, if any,įollowed by the kind of type (empty string for primitive typesĪnd class, enum, interface, interface, as appropriate), followedīy the type's name, followed by an angle-bracketedĬomma-separated list of the type's type parameters, if any.Ī space is used to separate modifiers from one another and to Information about modifiers and type parameters. Returns a string describing this Class, including ("The name of class Foo is: "+()) Since: JDK1.0 See Also: fineClass(byte, int, int), Type (or for void) using a class literal. It is also possible to get the Class object for a named The following example uses a Class object to print the Objects are constructed automatically by the Java Virtual Machine as classesĪre loaded and by calls to the defineClass method in the class The primitive Java types ( boolean,Ĭlass has no public constructor. That is shared by all arrays with the same element type and number Every array alsoīelongs to a class that is reflected as a Class object An enum is a kind ofĬlass and an annotation is a kind of interface. Interfaces in a running Java application. Instances of the class Class represent classes and
