Write an inheritance hierarchy for classes Quadrilateral, Trapezoid, Parallelogram, Rectangle and Square. Use Quadrilateral as the superclass of the hierarchy. Create and use a Point class to represent the points in each shape. Make the hierarchy as deep (i.e., as many levels) as possible. Specify the instance variables and methods for each class. The private instance variables of Quadrilateral should be the x-y coordinate pairs for the four endpoints of the Quadrilateral. Write a program that instantiates objects of your classes and outputs each object‟s area (except Quadrilateral
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)
3
4 Coordinates of Parallelogram are:
5 (5.0, 5.0), (11.0, 5.0), (12.0, 20.0), (6.0, 20.0)
6 Width is: 6.0
7 Height is: 15.0
8 Area is: 90.0
9
10 Coordinates of Rectangle are:
11 (17.0, 14.0), (30.0, 14.0), (30.0, 28.0), (17.0, 28.0)
12 Width is: 13.0
13 Height is: 14.0
14 Area is: 182.0
15
16 Coordinates of Square are:
17 (4.0, 0.0), (8.0, 0.0), (8.0, 4.0), (4.0, 4.0)
18 Side is: 4.0
19 Area is: 16.0

Write a python function to compute a certain number to a given power. The program should continue asking the user for number and power and display the result until the user enters 0 as the number. Note: don't use the power function of Python. Compute the power using a for or a while loop.
while True:
number = int(input("input the number: "))
exponent = int(input("input the exponent : "))
if number == 0:
break
else:
result = 1
while exponent != 0:
result *= number
exponent-=1
print("Answer = " + str(result))
we are asked not to use the power function of python. The question wants us to use a for or a while loop to compute the power.
The while loop makes sure the user is always asked to input the number and an exponent.
If the users number equals 0, the while loop will break.
Else the code will find the power of the number.
Finally, we print the answer if the user number is not zero

Each road is associated with a value indicating the level of danger in maintaining that road during winter months. There are many subsets of roads such that the roads in such subsets keep the towns connected directly or indirectly. Each subset is assigned a cost of maintenance, which is directly proportional to the highest danger level of the road present in that subset. The engineer wants to select the smallest subset that keeps the towns connected directly or indirectly and that also has the lowest cost of maintenance. Develop an algorithm to find such a subset. Justify the correctness of your algorithm and derive its runtime.
Answer:
Each road is associated with a value indicating the level of danger in maintaining that road during winter months. There are many subsets of roads such that the roads in such subsets keep the towns connected directly or indirectly.

Computer Software is a programming code executed on a computer processor.We can see and also use the software but can’t touch them. (Ms Word, Excel, Power Point, Photoshop..etc..)
Hardware can't perform tasks without software. And Software can't be executed without software.

Hardware is not affected by computer viruses. Software is affected by computer viruses.
In the EXPLORE online library, the ratio of the number of novels to that of dictionaries is 2:3 and the total number of novels is 624. If Joe buys more novels and the ratio becomes 7:3, then how many novels have been bought in total?
Answer:
Answer is 2184
Explanation:
1st of all we need to know the total number of novels in the library if I have it with a ratio of one meaning:
2---------624
1----------???
(1×624)÷2 =312
Meaning with a ratio of 1 I'll have 312
Take the 312 and multiply with 7
It will give you 2184

Write a function named parts that will take in as parameters the dimensions of the box (length, width, and height) and the radius of the hole, and returns the volume of material remaining. Assume the hole has been drilled along the height direction. Note: first write the function assuming the hole has radius less than min(length/2, width/2). For full credit, you will need to account for larger radii (bigger than half the length or width of the box).
The function in Python where comments are used to explain each line is as follows:
#This defines the parts() function
def parts(length, width, height, radius):
#This calculates the volume of the box
VBox = length * width * height
#This calculates the volume of the hole
VHole = 3.142 * radius ** 2 * height
#This calculates the remaining volume
Volume = VBox - VHole
#This returns the volume of the remaining material
return Volume

Product prod2 = new Product();
prod2.Barcode = 987654;
System.out.println(prod1.Barcode);
System.out.println(prod2.Barcode);
}
}
public class Product {
public int Barcode;
}
Answer:
Explanation:
1st mistake: Barcode is written with upeer case, that's not the convention for variables in java, only classes.
2nd: Barcode is public, it is convention to always leave variables private then create getters and setters in case you need to change the value but never acess the variable outside the class it belongs. Also the class should at least have a default constructor in case you are going to instantiate an object outside it.
so the product class should be:
--------------------------------------------------------------------
public class Product {
private int barcode;
public Product() {
// default constructor
}
public int getBarcode() {
return barcode;
}
public void setBarcode(int barcode) {
this.barcode = barcode;
}
}
-------------------------------------------------------------------------
3rd: in the main class now you can instantiate the 2 objects but you are gonna set the variable and get the value through the method, like this:
public class Main {
public static void main(String[] args) {
Product prod1 = new Product();
prod1.setBarcode(123456);
Product prod2 = new Product();
prod2.setBarcode(987654);
System.out.println(prod1.getBarcode());
System.out.println(prod2.getBarcode());
}
}
-----------------------------------------------------------------------------------
Assuming the 2 classes (main and product) are in the same package. But in case they are in different packages, just make sure to import the Product class into the Main class so that you can instantiante an object (new Product()) of it.
