Suppose you are implementing the Comparable interface in a class representing a Book, where the ordering is based on the number of pages in the book. Write a compareTo method for this class. You may assume that in the Book class there is an instance variable called numPages and a method called getNumPages.

Answers

Answer 1

Answer:

Following are the code to this question:

public class Book implements Comparable<Book> //defining a class that inherits the interface

{

int numPage; //defining integer variable numPage

int getNumPage()//defining a method getNumPage

{

return numPage; //use return keyword to return numPage value

}

int compareTo(Book b)//defining a method compareTo that uses Book instance b

{

   //using multiple conditions

if (getNumPage() > b.getNumPage())//defining if block that checks getNumPage method value is greater then instance of getNumPage  

{

return 1; //return value 1

}

else if (getNumPage() == b.getNumPage())//defining else if block that checks method and its instance value is euqal    

{

return 0;//return 0

}

else //defining else block

{

return -1;//return value -1

}

}

}

Explanation:

In the above-given code, a class book is defined, that inherits the interface that is "Comparable<Book>". Inside the class, an integer variable "numPage" and a method "getNumPages" is defined, that returns the "numPage" value.

In the next step, the "compareTo" method is declared, which uses an instance of the book and use the conditional statement.

In the if block, It checks the "getNumPages" method value is greater than the instance of the "getNumPages" method if the value is true, it will return "1", otherwise goto else if block. In this block, it will check both "method and instance of method" values are equal, if the condition is true, it will return "0". In the else block, if the above condition is false, it will return the value that is "-1".

The following system is ideal for representing large, sparsely-populated tables that have a need for real-time, read-write random access.
A. Hadoop
B. MS SQL Server
C. HBase
D. Hive

Answers

Answer:

The correct answer is C. HBase.

Explanation:

HBase is a database system written in the Java programming language. It is open-source and can store enormous amounts of data in tables in billions of rows and columns. It enables random read and write operations in real time. In HBase, the query fetch time is less. It is designed to store denormalized data in wide and sparsely populated tables in contrast to the relational database management system.

Answers

Complete Question:

Write a program that contains the following two methods:

/** Convert from feet to meters */

public static double footToMeter(double foot)

/** Convert from meters to feet */

public static double meterToFoot(double meter)

The formula for the conversion is: meter = 0.305 * foot and foot = 3.279 * meter Write a test program that invokes these methods. PLEASE WRITE IN JAVA.

Answer:

//Declare the class

public class Converter{

   

    //method footToMeter that receives the foot as parameter

    public static double footToMeter(double foot){

        //declare a double variable called meter,

        //to hold the result of the conversion

        double meter;

       

        //using the given formula, conver the foot to meter and

        //store the result in the meter variable

        meter = 0.305 * foot;

       

        //return the result stored in meter

        return meter;

    }

   

   

    //method meterToFoot that receives the meter as parameter

    public static double meterToFoot(double meter){

        //declare a double variable called foot,

        //to hold the result of the conversion

        double foot;

       

        //using the given formula, convert the meter to foot and

        //store the result in the foot variable.

        foot = 3.279 * meter;

       

        //return the result stored in foot.

        return foot;

    }

   

   

    //Test program to invoke those methods

    public static void main(String []args){

           

           //Convert 120 feet to meter

           System.out.println("120 feet to meter is " + footToMeter(120));

           

           //Convert 36 meters to foot

           System.out.println("36 meters to feet is " + meterToFoot(36));

    }

   

   

}  //End of class declaration

Sample Output:

120 feet to meter is 36.6

36 meters to feet is 118.044

What do you think is the most important factor affecting the collection of digital data and what impact do you think that this factor has on the ultimate quest for obtaining evidence in a criminal case?

Answers

Answer:

Privacy concerns.

Explanation:

Privacy concerns have played an important role in how we collect digital data. For example, privacy activists believe that an individual has the right to know how his or her information is being used and that such an individual also has the right to withhold such information.

Such issues have affected the ability of law enforcement agencies to investigate criminal activities. For example, an individual who is accused of a crime may claim a right to withhold his personal information, such as his mobile device, and thus he refuses to give out such information.

The most important factor affecting the collection of digital data is privacy.

What is digital data?

Digital data simply means information that's is represented bas discrete symbols. An example is a document that has a string of alphanumeric characters.

The use of encryption and authentication protocols is the standard method of countering attempts to alter or insert transmissions.a) trueb) false

Answers

Answer:

a) true.

Explanation:

Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.

Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.

On the other hand, authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.

Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification.

Digital certificates, smart cards, picture passwords, and biometrics are used to perform an authentication.

Hence, in cybersecurity the use of encryption and authentication protocols is the standard method of countering attempts to alter or insert transmissions.

Answer:

D. Network tap

Explanation:

A network tap is a hardware device that provides a way to access the data flow across a computer network.

A sniffer is either hardware or software that provides a way to access the data flow across a computer network.

Hence, these two IDS components are very similar.

Cheers.

A network tap is the same as a sniffer in that it runs in conjunction with a network card in promiscuous mode. Therefore, option D is correct.

What is network tap?

A network tap can be described as a system that monitors events on a local network. A tap is a dedicated hardware device, which offers a way to access the data flowing across a network.

The network tap has three ports which are an A port, a B port, and a monitor port. A tap inserted between A and B passes all traffic via unimpeded in real-time, but copies that same data to its monitor port, enabling a third party.

Network taps are generally used for network intrusion detection systems, network probes, packet sniffers, RMON probes, and other monitoring and collection devices and software that need access to a network segment.

Taps are utilized in security applications because they are non-obtrusive, are not detectable on the network, and will pass through or bypass traffic even if the tap stops working.
