I'm confused as to if subclasses can call the supers without any implementation and what the right answer is
Answers
Answer:
E
Explanation:
Since Example1 and Example2 inherit from Example0, all classes have the method doNothing() at their disposal, so you can call it from e0, e1 and e2.
However, the arguments of this method are Example1 and Example2, so you cannot pass Example0 as a first argument, and you cannot pass Example0 or 1 as a second argument. That only leaves answer E.
You can call the inheritance relation an "is a kind of" relation. So Example1 is a kind of Example0, and Example2 is a kind of Example1, but also Example2 is a kind of Example0.
Now you can understand why e2 can be passed as an argument for Example1, because e2 is a kind of Example1.

hi there!
Answer:
1. cat6 cable
2. wireless ethernet router
3. cat5e cable
Explanation:
1. you need a cat6 cable to be capable to deliver the gigabyte ethernet data to the network device.
2. you need a wireless device to provide wireless connection to her notebook.
3. for a printer no cat6 is necessary you can use cat5e cable and it will be enough.
hope this helps.
Connection to the gigabit ethernet network must be done with Cat6 Cable. Using the wireless ethernet router as the network device and connecting the cable to the printer must be done with Cat5e Cable.
We can arrive at this answer because:
The Cat6 Cable will be responsible for establishing a bridge between the gigabyte Ethernet and the network device, allowing data delivery to be made between the two systems.This connection must be made with a wireless device, to keep it more stabilized and it needs, mainly, for the notebook to receive the internet signal. This will be done using the wireless ethernet router.The printer needs a softer, less rigid connection, so a Cat5e cable will be a convenient option.In this case, we can see that using these devices will allow Lori to have a more stable and efficient connection to meet her needs.
