The GNU/Linux operating system comes with many built-in utilities for getting real work done. For example, imagine you had to an

alyze thousands of files as part of a digital forensics investigation. One utility you might use is the wc command, which prints the newline, word, and byte counts for a given file. For example, if a file contained the text "This is the first line.\nThis is the second.", the wc command would print 1 9 43 (i.e., 1 newline character, 9 words, 43 total characters). For this exercise, you will implement a similar utility. Create a new class named WordCount that has a single method named analyze that takes a string parameter named text and returns an array of three integers. This method should count the number of newlines, words, and characters in the given string. (The return value is an array of these three counts.) Note that a "word" is any sequence of characters separated by whitespace. Hint: You can use a Scanner to count the number of words in a string. The Scanner.next() method returns the next word, ignoring whitespace.

Write a program to calculate the great circle distance between two points on the surface of a sphere. If p1(x1, y1) and p2(x2,y2
Tamiku [17]

Answer:

import java.lang.*;

public class distance { public static double distance(double latitude1,

                                     double latitude2, double longitude1,

                                     double longitude2)

       {

      // Convert Latitude and Longitude to Radians

           longitude1 = Math.toRadians(longitude1);

           longitude2 = Math.toRadians(longitude2);

           latitude1 = Math.toRadians(latitude1);

           latitude2 = Math.toRadians(latitude2);

           

           double d_longitude = longitude2 - longitude1;

           double d_latitude = latitude2 - latitude1;

           double a = Math.pow(Math.sin(d_latitude / 2), 2)

                   + Math.cos(latitude1) * Math.cos(latitude2)

                   * Math.pow(Math.sin(d_longitude / 2),2);

           double val = 2 * Math.asin(Math.sqrt(a));

           // Radius of earth in kilometers is 6371

           double earth_radius = 6371;

           // Calculate and return the distance

           return(val * earth_radius);

       }

       // Main Method

       public static void main(String[] args)

       {

           double latitude1 = 67.32055555555556;

           double latitude2 = 83.31861111111111;

           double longitude1 = -1.7217899;

           double longitude2 = -1.6567799;

           System.out.println(distance(latitude1, latitude2,

                   longitude1, longitude2) + " K.M");

       }

   }

Explanation:

This program is implemented in Java programming language

The formula for the shortest distance between two points on the earth is:

Distance = 3963.0 * arccos[(sin(lat1) * sin(lat2)) + cos(lat1) * cos(lat2) * cos(long2 – long1)]

The latitude and longitude of the two points must be known

The latitude and longitude are converted into radians using built in methods in java.

Take value for the radius of the earth in Kilometers  6371;

Note that a seperate method has been created to calculate the distance

In the driver method (main), values for latitude and logitudes for both places have been hard-corded, then the method distance is called and passed those values

Note also that the distance has been calculated in Kilometers

_________ is the start up sequence a computer conducts.
Travka [436]

Answer:

Booting

Explanation:

Booting is the start up sequence a computer conducts when it is being turned on. The booting is done by the operating system. The booting process is usually started when a hardware on the computer is pressed or by a software command. For a windows computer, the BIOS is used to start the booting sequence. These boot sequence is called boot order or BIOS boot sequence.

Which components of the​ five-component model is commonly thought of as the​ "bridge" that links the computer side of the model
-Dominant- [34]

Answer:

The correct answer to the following question will be "Data".

Explanation:

  • Data would be any series of one or even more signs which are given significance by unique classification action. To become knowledge the data needs to be interpreted.
  • Data is generally considered to be the "bridge" that connects the designer's machine part with the practical side.

Therefore, this will be the right answer.

When a user utilizes another computer to communicate with a third party, with the result that the third party cannot recognize t
avanturin [10]

Answer:

Online or Web Proxy

Explanation:

Web or online proxy allows you to hide your Internet Protocol (IP) address from the website you are trying to visit or access. It is like a shield between the website you are accessing and you. They can be seen as a middleman between you and the site you are visiting and as such, the site sees that a specific IP address is accessing its server but the address is not yours as all requests between your computer and the web server are first passed through the proxy server.
