Answer:
The output is "A"
Explanation:
public class Solution {
public static void main(String args[]) {
mystery(7);
}
public static void mystery(int a) { System.out.println("A"); }
public static void mystery(double a) { System.out.println("B"); }
public static void mystery(int a, double b) { System.out.println("C"); }
public static void mystery(double a, int b) { System.out.println("D"); }
}
In the code above; mystery is defined in four different ways called method overloading. Method overloading is when same method is defined with different parameters.
In the first case; mystery will be called if the argument is int.
In the second case; mystery will be called if the argument is double.
In the third case; mystery will be called if the arguments are int and double.
In the fourth case; mystery will be called if the arguments are double and int.
When mystery(7) is called; the mystery method requiring only int will be called and the output is "A".
Answer:
b. Any metadata that an online tool produces (for example, data about a student’s usage of a tool, or how much time it took them to take an assessment or look at a video) is not protected if it is not tied to any identifying information.
Explanation:
The content form educational tools that are online that is not protected under FERPA(Family Education Rights and Privacy Act) is any metadata that is produced by the online tool.That metadata can contain data about student's usage of a tool etc.
FERPA governs the access educational information and records by public entities.
