Is it possible to use Java Reflection to print out attributes of the parent class?

Question

is it possible to use Java Reflection to print out the attributes of a parent class.

You can navigate the class hierarchy, you can reflect class attributes, so why not? — Jim Blackler, May 23 '11 at 15:11

Yes, you could do something like this:

Class<?> parentClass = getClass().getSuperclass();

Field[] fields = parentClass.getDeclaredFields();
for (Field field : fields) {
    System.out.println("field: " + field.getName());
}

Method[] methods = parentClass.getDeclaredMethods();
for (Method method : methods) {
    System.out.println("method: " + method.getName());
}

Given an appropriately permissive security policy, it is possible to print out any class/instance's attributes using reflection. See How to limit setAccessible to only "legitimate" uses? for some interesting discussion.
