Answer:
d. if (radius > 0) System.out.println(radius * radius * 3.14159);
Explanation:
The positive values are those values that are greater than 0(zero).0 is considered to be nonnegative number it is neither positive nor negative and for a zero radius the area will be 0.As we know the are of the circle is π*radius*radius, and π is 3.14159.So the correct answer matching to this condition is option d.
Which checks if the radius is greater than 0 then find the radius and print it.
You can make a hierarchical directory structure under /root that
consists of one directory containing subdirectories by using cd and
mkdir
the mkdir command created the directories while the cd command changes which directory you're currently in
Answer:
I don't think so. In today's computer era, many different solution directions exist for any given problem. Where OOP used to be the doctrine of choice, now you would consider it only when the problem at hand fits an object-oriented solution.
Reason 1: When your problem can be decomposed in many different classes with each many instances, that expose complex interactions, then an OO modeling is justified. These problems typically produce messy results in other paradigms.
Reason 2: The use of OO design patterns provides a standardized approach to problems, making a solution understandable not only for the creator, but also for the maintainer of code. There are many OO design patterns.
