Method Summary
`static String` | `getPackageName(Class<?> cls)` Returns the package name of `cls` according to the Java Language Specification (section 6.7).
`static String` | `getPackageName(String classFullName)` Returns the package name of `classFullName` according to the Java Language Specification (section 6.7).
`static void` | `initialize(Class<?>... classes)` Ensures that the given classes are initialized, as described in JLS Section 12.4.2.
`static
`<T> T`
` | `newProxy(Class<T> interfaceType, InvocationHandler handler)` Returns a proxy instance that implements `interfaceType` by dispatching method invocations to `handler`.

Method Detail

### getPackageName

    public static String getPackageName(Class<?> cls)

  Returns the package name of `cls` 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

    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

    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 inter-operating with a legacy framework, this method helps to keep the code less ugly.

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

### newProxy

    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(java.lang.ClassLoader, java.lang.Class[], java.lang.reflect.InvocationHandler)`.

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