Answer:

a. Object cannot be converted to Person

Explanation:

This program demonstrates polymorphism.

e.g., a Student IS a Person therefore you can call m() with a Student as well as a Person object.

The same goes for GraduateStudent.

However, and Object is not a Person, so the last call fails. This can be deducted by the type checking that happens at compile time.

Define global variables called highestNum, userInput and sumOfNums and initialize them. In Main call 2 methods: 1) UserData() 2)
Montano1993 [528]

Answer:

Explanation:

The following code is written in Java. It creates the two methods as requested using the Scanner and Random built-in classes in Java. Once the loop is completed and the highestNum is calculated, then the displayResults method is called to print out all the information in the correct format. The output of the program can be seen in the attached image below.

import java.util.Random;

import java.util.Scanner;

class Brainly {

   static int highestNum = 0;

   static int userInput;

   static int sumOfNums = 0;

   public static void main(String[] args) {

       userData();

       displayResults();

   }

   private static void userData() {

       Scanner in = new Scanner(System.in);

       Random rand = new Random();

       System.out.println("Enter a number between 9 and 20: ");

       userInput = in.nextInt();

       if ((userInput >= 9) && (userInput <= 20)) {

           for (int i = 0; i < userInput; i++) {

               int num = rand.nextInt(100);

               if (num > highestNum) {

                   highestNum = num;

               }

               sumOfNums += num;

           }

       }

   }

   public static void displayResults() {

       System.out.println("There were " + userInput + " numbers generated");

       System.out.println("The highest number generated is " + highestNum);

       System.out.println("The sum of the numbers is " + sumOfNums);

       int average = sumOfNums / userInput;

       System.out.println("The average of the numbers is " + average);

   }

}

When you use the ip address of the web server, the correct site is displayed?
jekas [21]
No. Using the address will get you either the default site, or the first site declared. Web servers can host VirtualHosts, and rely on the site name to know which VirtualHost to serve. TMI, it's called name based virtual host, as opposed to the machine having many addresses then address based virtual hosts can be created.

Algorithm and flowchart to find the perimeter and area of square​
kupik [55]

Answer:

I can give you the perimeter "algorithm" but not the flowchart.

Here you go:

p = w * 4

p = perimiter,

w = width/height

4 = the amount of sides needed.

perimeter = width * 4

to include both width and height, we would instead use:

perimeter = 2(width+height)

This also works with rectangles ^

--------------------------------------------------------------------------

To find an area, it is just width * height. This is also compatible with rectangles.
