Answer:
Correct answer is option B (The reason for using supertypes is to minimize the number of nulls and to minimize the likelihood of redundant relationships)
Explanation:
Entity supertype
A entity supertype is a generic entity type which is related with one or more subtypes.
Use of entity supertype:
The reason for using entity supertype is to reduce redundant relationships and it is also used to minimize the number of nulls.

Answer:
- import java.util.Scanner;
-
- public class Main {
- public static void main (String [] args) {
-
- int jersey_num [] = new int[5];
- int rating [] = new int[5];
-
- Scanner inStream = new Scanner(System.in);
-
- for(int i=0; i < 5; i++){
- System.out.print("Enter player " + (i+1) + "'s jersey number:");
- jersey_num[i] = inStream.nextInt();
-
- System.out.print("Enter player " + (i+1) + "'s rating:");
- rating[i] = inStream.nextInt();
- }
-
- System.out.println("ROSTER");
-
- for(int j=0; j < 5; j++){
- System.out.println("Player " + (j+1) + "-- Jersey number: " + jersey_num[j] + ", Rating: " + rating[j]);
- }
- }
- }
Explanation:
The solution code is written in Java. Firstly create two array, jersey_num and rating, with int type. This is to hold the five pairs of numbers input by user (Line 6 -7).
Next, create a for loop that run for 5 iterations and in each iteration prompt user to input jersey number and rating (Line 11 -17). The input number and rating will be set to the array, jersey_num and rating, respectively.
Next, print the title "Roster" (Line 19).
Create another for loop to display the five input pair of values (Line 21 - 23).
they should have a fund raiser and collect money and then put up strong fire walls on all the computers
