Answer: (B) Symmetric key encryption
Explanation:
The symmetric key encryption is the computerize cryptography form that are used to show an electronic message by using the key the singular encryption. It is basically used in various mathematical algorithm for the purpose of data conversion.
In the symmetric key encryption, the computer system contain the secret key which is basically used to send the encrypt information in the form of packet over the network from one computer to another.
Therefore, Option (B) is correct.
Answer:
Explanation:
The following code is written in Java. It is a method that takes in the two parameters as requested and checks whether or not the index exists in the array. If it does then it replaces the String in that Index with the new castMemberName String parameter that was given. If the replacement is successful then it returns a True boolean, if not then it returns a False boolean. The array being used must be named castNames and have a global scope to be accessible by the method since it is not passed as a parameter.
public static boolean replaceCastMember(int index, String castMemberName) {
System.out.println(castNames.size());
if (index <= castNames.size()) {
castNames.remove(index);
castNames.add(index, castMemberName);
return true;
} else {
return false;
}
}
