Answer: Identifying sequences
Explanation:
Since the user wants to know if there are any particular activities that the customers engage in, or the types of purchases made in the month before or after purchasing select items from your store, therefore, the data mining software can be used in identifying sequences.
In this case, the data mining software can't be used in classifying data whether into structured or unstructured data. Furthermore, the identification of clusters and associations aren't the correct answers.
Therefore, the best option is B.
Answer:
D) They can be accessed by any method in the same program
Explanation:
Public methods is a form of access modifier in a programming language such as Java, Phython, C#. However, unlike other types of access modifiers like Private Methods, Protected Methods etc they do not put any form of restriction on the access. Hence, in Public Methods members, methods and classes can be accessed from anywhere.
Therefore, what is true of Public Methods is that, they can be accessed by any method in the same program
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;
}
}
}
