What are the two jobs of super?
Short answer. Calling the parent constructor, and calling the parent's version of a method.
Where must super() appear?
As the very first statement in the constructor.
Remember
| super(): parent constructor |
| super.m(): parent method |
The word super has two jobs. Do you know both? Super with brackets calls the parent constructor. It must be the first line. Super dot info calls the parent method. Super brackets calls the constructor. Super dot calls the method.
