For this lab you will write a class to create a user-defined type called Shapes to represent different shapes, their perimeters and their areas. The class should have three fields: shape, which is of type string, and perimeter and area of type double. The program will have to be able to calculate perimeters and areas for circles, triangles, squares and rectangles, which are the known shapes.
2.1 Constructors
Write these constructors:
1. Default constructor that sets the shape to "unknown" and the perimeter and area to 0
2. Constructor with one parameter, shape, that sets the shape, other fields are 0
2.2 Accessors & Mutators
Write the following member methods:
1. setShape()
Modifies the shape field
2. getShape()
Returns the shape field
3. getPerimeter()
Returns the perimeter field
4. getArea()
Returns the area field
Arithmetic Methods in Interface
Write the following member methods to perform arithmetic:
1. setPerimeter(Scanner scnr)
Depending on the shape, prompts the user for appropriate variables (ie width & height for a square, radius for a circle, etc.) and calculates the perimeter of the appropriate shape. The perimeter field should be updates with the new value. If the shape is unknown, then print to the screen that the user must first define a shape before a perimeter can be calculated and set the perimeter to 0.
2. setArea(Scanner scnr)
Depending on the shape, prompts the user for appropriate variables (ie width & height for a square, radius for a circle, etc.) and calculates the area of the appropriate shape. The area field should be updates with the new value. If the shape is unknown, then print to the screen that the user must first define a shape before an area can be calculated and set the area to 0.
2.3 Additional Methods
Create two additional methods of your choice. Be sure to clearly label both of these methods as your own.
2.4 Using another .java file called ShapesTest.java that tests that all of your methods work correctly

}
//2. Method to find and show the difference between the area and perimeter of a shape
public void getDifference(){
double diff = this.getArea() - this.getPerimeter();

System.out.println("The difference is " + diff);
}
}
========= ShapeTest.java ===========
import java.util.Scanner;
public class ShapeTest {
public static void main(String [] args){
Scanner scanner = new Scanner(System.in);
// create an unknown shape
Shape shape_unknown = new Shape();
//get the shape

}
}
Sample output:
The shape is unknown
You must define a shape first before calculating area

Write a Python program that allows the user to enter any number of non-negative floating-point values. The user terminates the input list with any negative value. The program then prints the sum, average (arithmetic mean), maximum, and minimum of the values entered. Algorithm: Get all positive numbers from the user Terminate the list of numbers when user enters a negative
Answer:
The program in Python is as follows:
nums = []
isum = 0
num = int(input("Num: "))
while num >= 0:
isum+=num
nums.append(num)
num = int(input("Num: "))
print("Sum: ",isum)
print("Average: ",isum/len(nums))
print("Minimum: ",min(nums))
print("Maximum: ",max(nums))
Explanation:
My solution uses list to answer the question
This initializes an empty list, num
nums = []
This initializes the sum of the input to 0
isum = 0
This prompts the user for input
num = int(input("Num: "))
The loop is repeated until the user enters a negative number
while num >= 0:
This calculates the sum of the list
isum+=num
This appends the input to the list
nums.append(num)
This prompts the user for another input
num = int(input("Num: "))
This prints the sum of the list
print("Sum: ",isum)
This prints the average of the list
print("Average: ",isum/len(nums))
This prints the minimum of the list
print("Minimum: ",min(nums))
This prints the maximum of the list
print("Maximum: ",max(nums))

Implement your interface from Chapter using event handling In Chapter your assignment was to Design a universal remote control for an entertainment system (cable / TV, etc). Create the interface as an IntelliJ project. Or to design the telephone interface for a smartphone. Also, create the interface as an IntelliJ project In this assignment, you need to have event listeners associated with the components on the GUI.
The assignment cannot be created using the GUI Drag and Drop features in NetBeans. You must actually code the GUI application using a coding framework similar to one described and illustrated in chapter on GUI development in the courses textbook.
In this assignment you need to have event listeners associated with the components on the GUI. This assignment is about creating a few event handlers to acknowledge activity on your interface. Acknowledgment of activity can be as simple as displaying a text message when an event occurs with a component on your interface such as; a button is pressed, a checkbox or radio button is clicked, a slider is moved or a combo box item is selected.

Design 3 classes: Computer - Superclass
Laptop - Subclass
Desktop - Subclass
You will design these classes to optimize the superclass/subclass relationship by creating instance variables and getter/setter methods.
Include the following instance variables:
int screenSize -
Inches of monitor space
int memory - GB of ram
double batteryLife - Hours of battery life
boolean monitor - Whether or not a monitor is included
Each class should have at least one variable in it.
Once completed, the Tester class should execute without error.
Answer:
Explanation:
The following code is written in Java. It creates the three classes mentioned and a Tester class that contains the main method. The Computer class contains the memory variable since both laptops and Desktops need memory. The screen size variable is placed separately in the Laptop and Desktop class since desktops may or may not have a monitor so this variable cannot be placed in the Computer class. The batteryLife variable is only in the Laptop class because Desktops do not have batteries. Finally, the monitor variable is only placed in the Desktop class since Laptop's come with built-in monitors. The tester class seen in the picture below tests the creation of both of these objects and it executes without any error.
class Computer {
int memory;
public int getMemory() {
return memory;
}
public void setMemory(int memory) {
this.memory = memory;
}
}
class Laptop extends Computer {
int screenSize;
double batteryLife;
public int getScreenSize() {
return screenSize;
}
public void setScreenSize(int screenSize) {
this.screenSize = screenSize;
}
public double getBatteryLife() {
return batteryLife;
}
public void setBatteryLife(double batteryLife) {
this.batteryLife = batteryLife;
}
}
class Desktop extends Computer {
boolean monitor;
int screenSize;
public boolean isMonitor() {
return monitor;
}
public void setMonitor(boolean monitor) {
this.monitor = monitor;
}
public int getScreenSize() {
return screenSize;
}
public void setScreenSize(int screenSize) {
this.screenSize = screenSize;
}
}
class Tester {
public static void main(String[] args) {
Laptop computer1 = new Laptop();
Desktop computer2 = new Desktop();

The function below takes one parameter: an integer (begin). Complete the function so that it prints every other number starting at begin down to and including 0, each on a separate line. There are two recommended approaches for this: (1) use a for loop over a range statement with a negative step value, or (2) use a while loop, printing and decrementing the value each time.
1 - def countdown_trigger (begin):
2 i = begin
3 while i < 0:
4 print(i)
5 i -= 1 Restore original file
Answer:
Follows are code to the given question:
def countdown_trigger(begin):#defining a method countdown_trigger that accepts a parameter
i = begin#defining variable that holds parameter value
while i >= 0:#defining while loop that check i value greater than equal to0
print(i)#print i value
i -= 2 # decreasing i value by 2
print(countdown_trigger(2))#calling method
Output:
2
0
None
Explanation:
In this code, a method "countdown_trigger" is declared, that accepts "begin" variable value in its parameters, and inside the method "i" declared, that holds parameters values.
By using a while loop, that checks "i" value which is greater than equal to 0, and prints "value" by decreasing a value by 2.

1-(50 points) The function sum_n_avgcomputes the sum and the average of three input arguments and relays its results through two output parameters.a)Write a prototype for a function sum_n_avgthat accepts three double-type inputparameters and returns two output parameters through reference.b)Write the function definition for function sum_n_avg. The function definition is where the actual computations are performed.c)Write a function call in main ()forsum_n_avg. The function call can look like below free
Answer:
The program in C++ is as follows:
#include <iostream>
using namespace std;
double *sum_n_avg(double n1, double n2, double n3);
int main () {
double n1, n2, n3;
cout<<"Enter 3 inputs: ";
cin>>n1>>n2>>n3;
double *p;
p = sum_n_avg(n1,n2,n3);
cout<<"Sum: "<<*(p + 0) << endl;
cout<<"Average: "<<*(p + 1) << endl;
return 0;
}
double *sum_n_avg(double n1, double n2, double n3) {
static double arr[2];
arr[0] = n1 + n2 + n3;
arr[1] = arr[0]/3;
return arr;
}
Explanation:
This defines the function prototype
double *sum_n_avg(double n1, double n2, double n3);
The main begins here
int main () {
This declares variables for input
double n1, n2, n3;
This prompts the user for 3 inputs
cout<<"Enter 3 inputs: ";
This gets user inputs
cin>>n1>>n2>>n3;
This declares a pointer to get the returned values from the function
double *p;
This passes n1, n2 and n3 to the function and gets the sum and average, in return.
p = sum_n_avg(n1,n2,n3);
Print sum and average
cout<<"Sum: "<<*(p + 0) << endl;
cout<<"Average: "<<*(p + 1) << endl;
return 0;
}
The function begins here
double *sum_n_avg(double n1, double n2, double n3) {
Declare a static array
static double arr[2];
Calculate sum
arr[0] = n1 + n2 + n3;
Calculate average
arr[1] = arr[0]/3;
Return the array to main
return arr;
}
SimpleScalar is an architectural simulator which enables a study of how different pro-cessor and memory system parameters affect performance and energy efficiency.
a. True
b. False
Answer:
a. True
Explanation:
SimpleScalar refers to a computer architectural simulating software application or program which was designed and developed by Todd Austin at the University of Wisconsin, Madison, United States of America. It is an open source simulator written with "C" programming language and it's used typically for modelling virtual computer systems having a central processing unit (CPU), memory system parameters (hierarchy), and cache.
The main purpose of SimpleScalar is to avail developers or manufacturers the ability to compare two computers based on their capacities (specifications) without physically building the two computers i.e using a simulation to show or illustrate that computer B is better than computer A, without necessarily having to physically build either of the two computers.
Hence, it is an architectural simulator which makes it possible to study how different central processing units (CPUs), memory hierarchy or system parameters and cache affect the performance and energy efficiency of a computer system.

which optical storage media has greatest storage capacity?
The optical storage media has greatest storage capacity is Single-layer, single-sided Blu-ray disc.
What is the Blu-ray disc.
A Blu-ray disc can store the most information compared to other types of optical discs. A one-sided Blu-ray disc can store around 25 GB of information.
Dual-layer or double-sided discs are discs that have two layers or two sides, which allows them to store more information. New Blu-ray discs with 20 layers can store up to 500 GB of data. Small DVDs can save about 4. 7 GB of data. A DVD that has two layers or can be played on both sides can store up to 8. 5 GB of data. If it is both dual-layer and double-sided, it can hold up to 17 GB of data.
