Create a program that uses an array of Shape references to objects of each concrete class in the hierarchy (see program-2). The program should print a text description of the object to which each array element refers. Also, in the loop that processes all the shapes in the array, determine the size of each shape If it‟s a TwoDimensionalShape, display its area. If it‟s a ThreeDimensionalShape, display its area and volum ​

Explanation:

In which wireless configuration type do nodes communicate directly with each other, rather than with an access point? In an AD-HOC network, all nodes communicate and transmit directly to each other.

The answer to your question is Developer.

Answer:

CODE:

public class QuadrilateralTest {

public static void main(String[] args) {

// NOTE: All coordinates are assumed to form the proper shapes

// A quadrilateral is a four-sided polygon

Quadrilateral quadrilateral =

new Quadrilateral(1.1, 1.2, 6.6, 2.8, 6.2, 9.9, 2.2, 7.4);

// A parallelogram is a quadrilateral with opposite sides parallel

Parallelogram parallelogram =

new Parallelogram(5.0, 5.0, 11.0, 5.0, 12.0, 20.0, 6.0, 20.0);

// A rectangle is an equiangular parallelogram

Rectangle rectangle =

new Rectangle(17.0, 14.0, 30.0, 14.0, 30.0, 28.0, 17.0, 28.0);

// A square is an equiangular and equilateral parallelogram

Square square =

new Square(4.0, 0.0, 8.0, 0.0, 8.0, 4.0, 4.0, 4.0);

System.out.printf(

"%s %s %s %s\n", quadrilateral, parallelogram,

rectangle, square);

}

}

RESULT:

Coordinates of Quadrilateral are:

2 (1.1, 1.2), (6.6, 2.8), (6.2, 9.9), (2.2, 7.4)

The solution is the recursive Python 3 function below:

########################################################

def allNamePermutations(listOfNames):

   # return all possible permutations of listOfNames

   if len(listOfNames) == 0 or len(listOfNames) == 1:

       # base case

       return [listOfNames]

   else:

       # recursive step

       result_list = [ ]

       remaining_items = [ ]

       for firstName in listOfNames:

           remaining_items = [otherName for otherName in listOfNames if

                                                                     (otherName != firstName)]

           result_list += concat(firstName,

                                              allNamePermutations(remaining_items))

       return result_list

#######################################################

How does the above function work?

As with all recursive functions, this one also has a base case, and a recursive step. The base case tests to make sure the function terminates. Then, it directly returns a fixed value. It does not make a recursive call.

In the case of this function, the base case checked listOfNames to see if it was empty or only had one name. If any of the conditions were satisfied, a new list containing listOfNames is returned.

The recursive step is where the function allNamePermutations() calls itself recursively. The recursive step handles the case where listOfNames has more than one item. This step first iterates over each name in listOfNames, and then does the following;

        (By first getting the list of other names before passing it into

         allNamePermutations(), we make sure the recursive step eventually

         terminates. This is because we are passing a smaller list each time

         we make the recursive call.)

After the iteration, it returns the result list which will now contain all permutations of the names in the list.

The concat function is defined below

##################################################

def concat(name, listOfNameLists):

   # insert name in front of every list in listOfNameLists

   result_list = [ ]

   for nameList in listOfNameLists:

       nameList.insert(0, name)

       result_list.append(nameList)

   return result_list

#####################################################

If we run the sample test case below

####################################

name_list = ['Adam', 'Barbara', 'Celine']

allNamePermutations(name_list)

####################################

the following output is produced

[['Adam', 'Barbara', 'Celine'],

['Adam', 'Celine', 'Barbara'],

['Barbara', 'Adam', 'Celine'],

['Barbara', 'Celine', 'Adam'],

['Celine', 'Adam', 'Barbara'],

['Celine', 'Barbara', 'Adam']]

The first Industrial Revolution began in Great Britain in the mid-to-late 1700s, when innovation led to goods being produced in large quantities due to machine manufacturing.

This process began in Britain in the 18th century and from there spread to other parts of the world. Although used earlier by French writers, the term Industrial Revolution was first popularized by the English economic historian Arnold Toynbee (1852–83) to describe Britain's economic development from 1760 to 1840.

Answer:

Inheritance

Explanation:

The the code in the main method is run, it will print

"3 1, 3 2, 3 3"

The static/class field count stores the number of instances of the class created. count is always incremented when the instance constructor is called.

The instance field num acts like an identifier/serial number for the instance created. When the constructor is called, the current count is stored in the num field of the instance.

Each instance's toString( ) method will output the total count (from count) and the serial of the instance (from num).

When the code runs in the main method, it creates three instances (making count==3), so that we have

and implicitly calls toString( ) in the println method for each of the three instances to produce the following output

"3 1, 3 2, 3 3"
