Methods
Modifier and Type	Method and Description
`static boolean`	`classIs(Object object, Class<?> clazz)`
`static boolean`	`componentClassIs(Object object, Class<?> clazz)`
`static <T> Class<T>`	`getClass(T object)` 返回给定对象的类型。如果给定对象为 null 则返回 null. Returns given object class type. if given object is null return null.
`static String`	`getClassName(Object object)` Returns given object's full class name. e.g: org.codelogger.utils.ClassUtils If given object is null return empty string.
`static Class<?>`	`getComponentClass(Object object)` 返回给定对象的组件类型，如List<Long>的组件类型为Long 如果给定对象不是集合或数组，则返回null。 Returns the given object component type. If given object does not represent an array ,this method returns null.
