下面是一个使用 Java 反射获取所有继承类的示例代码: importjava.util.ArrayList;importjava.util.List;publicclassReflectionExample{publicstaticvoidmain(String[]args){List<Class<?>>subclassList=getAllSubclasses(MyClass.class);for(Class<?>subclass:subclassList){System.out.println(subclass.getName());}}pub...
getAllSubclassFields方法为入口方法,通过调用getAllSubclasses方法获取目标类的所有子类,再遍历子类调用getFields方法获取每个子类的字段,并将字段添加到字段列表中。 getAllSubclasses方法递归调用,通过targetClass.getDeclaredClasses()获取目标类的直接子类,然后再递归调用getAllSubclasses方法获取子类的子类,直到获取到所有子类。
for dynamically-generated FieldAccessorImpl and MethodAccessorImpl subclasses. (Use of the word "unsafe" was avoided in this class's name to avoid confusion with {@linksun.misc.Unsafe}.) </P> <P> The bug fix for 4486457 also necessitated disabling verification for this class and all subclass...
field.getAnnotations()使用的Field类的父类的AccessibleObject的getAnnotations方法;getAnnotations方法返回getDeclaredAnnotations方法; getDeclaredAnnotations方法的内容是throw new AssertionError("All subclasses should override this method"); 即是AccessibleObject类的所有子类必须覆盖这个方法。即正确的调用方式应该是调用...

The class loader for an array class, as returned by Class.getClassLoader() is the same as the class loader for its element type; if the element type is a primitive type, then the array class has no class loader. Applications implement subclasses of ClassLoader in order to extend the ...

A method is not required to declare in its throws clause any subclasses of Error that might be thrown during the execution of the method but not caught, since these errors are abnormal conditions that should never occur. That is, Error and its subclasses are regarded as unchecked exceptions fo...
