      • getPackageName

        public static  <?> clazz)
        Returns the package name of clazz according to the Java Language Specification (section 6.7). Unlike , this method only parses the class name, without attempting to define the and hence load files.

      • getPackageName

        public static   classFullName)
        Returns the package name of classFullName according to the Java Language Specification (section 6.7). Unlike , this method only parses the class name, without attempting to define the and hence load files.

      • initialize

        public static void <?>... classes)
        Ensures that the given classes are initialized, as described in .

        WARNING: Normally it's a smell if a class needs to be explicitly initialized, because static state hurts system maintainability and testability. In cases when you have no choice while inter-operating with a legacy framework, this method helps to keep the code less ugly.

        Throws:
        - if an exception is thrown during initialization of a class

      • newProxy

        public static <T> T <T> interfaceType,
                              handler)
        Returns a proxy instance that implements interfaceType by dispatching method invocations to handler. The class loader of interfaceType will be used to define the proxy class. To implement multiple interfaces or specify a class loader, use .
        Throws:
        - if interfaceType does not specify the type of a Java interface
