Answer:
A)
This is an example of tight coupling since the class Working has to have an idea of how Person is implemented to complete its own implementation.
B)
Any change in the Person class would require a change in the working class too.
C)
CODE
class Person {
int personID, age;
String fName, middleName, lastName;
public int getAge() {
return age;
}
}
// end of Person class
class Working extends Person {
boolean isUnderEighteen() {
if (super.getAge() <18) {
System.out.println("The person is under age and cannot work");
return true;
}
else {
System.out.println("The person can legitimately work");
return false;
}
}
}
Explanation:
A command you would use to perform a reverse lookup of the IP address 10.0.0.3 on a Linux system: dig -x 10.0.0.3.
<h3>What is a Linux command?</h3>

In Computer Networking, a command which an administrator (end user) would use to perform a reverse lookup of the IP address 10.0.0.3 on a Linux system is dig -x 10.0.0.3.

The stage of systems development in
which design specifications (such as the architecture, the modules, the interfaces,
and the data) are created is the stage of systems design. The purpose of systems
design is primarily to satisfy the specified requirements.
