Answer:

B. Symmetric key encryption

Explanation:

Symmetric key encryption is one in which a single encryption key is sent to the receiver so both sender and receiver share the same key. In this type of encryption, the sender uses a particular key to encrypt the data and sends the encrypted data (cipher data) to the receiver and then the receiver uses the same key to decrypt the data.

Public key encryption, or asymmetric encryption uses two keys - a private key and a public key. The public key is know to everyone while the private key is known only to those for whom the message is intended. An application of this type of encryption is in SSL (Secure Sockets Layer) - a protocol for transmitting data privately on the internet.

Private key encryption is not exactly one of the encryption methods but rather, a private key and a public key are used in encryption.

The best option is therefore <em>symmetric key encryption</em>.

Determine the best access modifier for each of the following situations: a. A class Employee records the name, address, salary,

Lorico [155]

Answer:

a. Protected

b. Public

Explanation:

There are four acess modifier in Java.

Default: Acessible only within the same package.

Public: Can be acessed by any class.

Private: Acessible only within the class.

For example, you have a class employee and a private method. This method can only be accessed by an object that is an instance of an employee.

Protected: Used in classes that extend each other. For example, a class of employees would extend employee.

So:

a. A class Employee records the name, address, salary, and phone number.

The best acesses modifier is protected. A class may extended employee but have the same arguments(name, adress, salary, phone number), so it should also have acess to the method.

b. An adding method inside of a class BasicMath.

This method can be used in a variety of packages and projects and classes... and there is no important information regarding security. So the best method is public.
