Answer:
A. One
Explanation:
Symmetric key cryptography makes use of one key. The same key is used for both encryption and decryption. This is different from asymmetric cryptography where separate keys are used for the two operations. Some examples of symmetric cryptography include:
- Advanced Encryption Standard (AES)
- Data Encryption Standard (DES)
- Triple Data Encryption Standard (3DES)
Here is my solution. I did the following:
- changed the setRemover into a constructor, since the comment seems to hint that that is expected.
- changed the lookFor type into a String, so that it can work with the string replace overload. That's convenient if you want to replace with an emtpy string. The char type won't let you do that, you can then only replace one char with another.
- Added a static Main routine to use the class.
import java.lang.System.*;
public class LetterRemover
{
private String sentence;
private String lookFor;
public LetterRemover() {}
// Constructor
public LetterRemover(String s, char rem)
{
sentence = s;
lookFor = String.valueOf(rem);
}
public String removeLetters()
{
String cleaned = sentence.replace(lookFor, "");
return cleaned;
}
public String toString()
{
return sentence + " - letter to remove " + lookFor;
}
public static void main(String[] args)
{
LetterRemover lr = new LetterRemover("This is the tester line.", 'e');
System.out.println(lr.toString());
String result = lr.removeLetters();
System.out.println("Resulting string: "+result);
}
}
Only technician A is correct.
Technician A only
<u>Explanation:</u>
According to technician A, tire fitment information provides specific specs of the vehicle including the inflation pressure, OEM tire size, and lug nut tire sequences. The class of vehicles is divided into a category of vehicles and these categories are further specialized to form different models. Each model has its own specifications and their requirements differ from one another.
Hence the tire fitment of each vehicle should convey specific information about the model in concern. For instance, the optimum inflation pressure of a Royal En field will not be the same as that of Hero Splendour as both have a huge difference in their respective weight and size.
