I have the following Java code
<code> Class<Integer> intClass = int.class;
Class<Integer> integerClass = Integer.class;
</code>
<code> Class<Integer> intClass = int.class;
Class<Integer> integerClass = Integer.class;
</code>
Class<Integer> intClass = int.class;
Class<Integer> integerClass = Integer.class;
intClass.getSuperClass() is null,
integerClass.getSuperClass() is java.lang.Number
How do we explain this?
