Explanation of Solution
“No”, it is neither ethical nor legal to broadcast the phone’s location to other parties or strangers without the consent of the consumer.
Introduction to GPS (Global Positional System):
The Global Positioning System termed as GPS, uses satellites to determine the current physical location.
It was originally created by the U.S. Department of Defense to improve military navigation. It is now available for consumer and used in cars, smartcards, handheld computers, and cell phones.
GPS helps to search a desired location for specific landmarks, such as restaurants and gas stations within a specific radius to current location. It also provides convenient turn-by-turn driving instructions to the destination.
Privacy invasion by smartphones due to location sharing:
This technology brings value to its users. However, it has caused a significant decrease in privacy. A combination of GPS data and cell tower triangulation can reveal the current location of smartphone.
According to the Electronic Frontier Foundation, “Location information collected by cellphone companies can provide an extraordinarily invasive glimpse into the private lives of cellphone users...

Answer the Java OOP question below:
Explain the relationship between a superclass and a subclass. How do the principles of encapsulation and abstraction play a role in this relationship? In your experience, how do you decide what should be included in a superclass versus a subclass? Share an example where a well-defined superclass-subclass hierarchy improved your code.
