Answer:
The best security which could be used to ensure integrity and validity of Access database is:
O. database password
Explanation:
Database password is the only option that best guarantee the integrity of an Access database due to the fact that, it limits the number of people who would be able to have access to it. This password is an administrative right given to those who are meant to access it and it is expected to be renewed every few months (probably every 3 months).
<em>Without the password, no other person can be able to login. Also, no two individual can be able to login in same time using same credential login details assigned (that is, in scenario of using the same Username and password)</em>
Answer:
import java.util.Scanner;
class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("How many numbers do you want to add?");
int numberOfNumbers = scanner.nextInt();
int arrayNumbers[] = new int[numberOfNumbers];
System.out.println("Enter " + numberOfNumbers + " numbers:\n");
for(int i = 0; i < numberOfNumbers; i++){
int addToArray = scanner.nextInt();
arrayNumbers[i] = addToArray;
}
int sum = 0;
for(int j = 0; j < arrayNumbers.length; j++){
sum+=arrayNumbers[j];
}
System.out.println("Sum: " + sum);
}
}
