getPackageName	back to summary
public static String getPackageName(Class<?> clazz) Returns the package name of `clazz` according to the Java Language Specification (section 6.7). Unlike `Class#getPackage`, this method only parses the class name, without attempting to define the `Package` and hence load files.

getPackageName	back to summary
public static String getPackageName(String classFullName) Returns the package name of `classFullName` according to the Java Language Specification (section 6.7). Unlike `Class#getPackage`, this method only parses the class name, without attempting to define the `Package` and hence load files.

initialize	back to summary
public static void initialize(Class<?>... classes) Ensures that the given classes are initialized, as described in JLS Section 12.4.2. 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 interoperating with a legacy framework, this method helps to keep the code less ugly. Exceptions ExceptionInInitializerError: if an exception is thrown during initialization of a class

public static void initialize(Class<?>... classes)

Ensures that the given classes are initialized, as described in JLS Section 12.4.2.

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 interoperating with a legacy framework, this method helps to keep the code less ugly.

Exceptions

ExceptionInInitializerError:: if an exception is thrown during initialization of a class

newProxy back to summary

newProxy	back to summary
public static <T> T newProxy(Class<T> interfaceType, InvocationHandler 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 `Proxy#newProxyInstance`. Exceptions IllegalArgumentException: if `interfaceType` does not specify the type of a Java interface

public static <T> T newProxy(Class<T> interfaceType, InvocationHandler 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 Proxy#newProxyInstance.

Exceptions

IllegalArgumentException:: if interfaceType does not specify the type of a Java interface
