Create a class to represent light bulbs
Create a class called Bulb that will represent a light bulb. It should have instance variables for the manufacturer (String), part number (String), wattage (int) and lumens (int). Get and Set methods should be included. Override the equals and to String methods from class Object.
List of Bulbs
Create a class called BulbNode which has fields for the data (a Bulb) and next (BulbNode) instance variables. Include a one-argument constructor which takes a Bulb as a parameter. (For hints, see the PowerPoint on "Static vs. Dynamic Structures".)
public BulbNode (Bulb b) {...}
The instance variables should have protected access. There will not be any get and set methods for the two instance variables.
Create an abstract linked list class called BulbList. This should be a linked list with head node as described in lecture. Modify it so that the data type in the nodes is Bulb. The no-argument constructor should create an empty list with first and last pointing to an empty head node, and length equal to zero. Include an append method in this class.
Create two more linked list classes that extend the abstract class BulbList: One called UnsortedBulbList and one called SortedBulbList, each with appropriate no-argument constructors. Each of these classes should have a method called add(Bulb) that will add a new node to the list. In the case of the UnsortedBulbList it will add it to the end of the list by calling the append method in the super class. In the case of the SortedBulbList it will insert the node in the proper position to keep the list sorted by wattage.
Instantiate two linked lists, and for every Bulb read from the file, add it to the unsorted and sorted lists using the add method. You will end up with the first list having the Bulbs from the input file in the order they were read, and in the second list the Bulbs will be in sorted order.
Display the unsorted and sorted Bulbs in a GUI with a GridLayout of one row and two columns. Put the unsorted Bulbs in the left column, and the sorted Bulbs in the right column.
The input file
There will be an input file provided on Blackboard which contains information about bulbs, one per line, with the manufacturer, part number, wattage and lumens separated by commas, such as:
Phillips, 1237DF2, 100, 1200
You can separate the four items using a StringTokenizer.
Submitting the Project.
You should now have the following files to submit for this project:
Project2.java
Bulb.java
BulbGUI.java
BulbNode.java
BulbList.java
UnsortedBulbList.java
SortedBulblist.java
Submit a jar file.
Rather than upload all the files above separately, we will use Java's facility to create the equivalent of a zip file that is known as a Java Archive file, or "jar" file.
Instructions on how to create a jar file using Eclipse are on Blackboard. Create a jar file called Project2.jar and submit that. Be sure the jar file contains source code, not classes.

Explanation:

Write a program named HoursAndMinutes that declares a minutes variable to represent minutes worked on a job, and assign a value to it. Display the value in hours and minutes. For example, 197 minutes becomes 3 hours and 17 minutes.'

Answers

Answer:

Explanation:

The following code is written in Python, it asks the user for the number of minutes worked. Divides that into hours and minutes, saves the values into separate variables, and then prints the correct statement using those values. Output can be seen in the attached image below.

import math

 

class HoursAndMinutes:

   min = input("Enter number of minutes worked: ")

   hours = math.floor(int(min) / 60)

   minutes = (int(min) % 60)

   print(str(hours) + " hours and " + str(minutes) + " minutes")

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

Answers

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.

You plan to make a delicious meal and want to take the money you need to buy the ingredients. Fortunately you know in advance the price per pound of each ingredient as well as the exact amount you need. The program should read in the number of ingredients (up to a maximum of 10 ingredients), then for each ingredient the price per pound. Finally your program should read the weight necessary for the recipe (for each ingredient in the same order). Your program should calculate the total cost of these purchases, then display it with 6 decimal places.

Example There are 4 ingredients and they all have a different price per pound: 9.90, 5.50, 12.0, and 15.0. You must take 0.25 lbs of the first, 1.5 lbs of the second, 0.3 lbs of the third and 1 lb of the fourth. It will cost exactly $29.325000.

Answers

Answer:

In Python:

prices = []

pounds = []

print("Enter 0 to stop input")

for i in range(10):

   pr = float(input("P rice: "+str(i+1)+": "))

   pd = float(input("Pound: "+str(i+1)+": "))

   if pr != 0 and pd != 0:

       prices.append(pr)

       pounds.append(pd)

   else:

       break

amount = 0

for i in range(len(pounds)):

   amount+= (pounds[i]*prices[i])

print("Amount: $",amount)

Explanation:

These initialize the prices and pounds lists

prices = []

pounds = []

This prompts the user to enter up to 10 items of press 0 to quit

print("Enter 0 to stop input")

This iterates through all inputs

for i in range(10):

This gets the price of each item

   pr = float(input("P rice: "+str(i+1)+": "))

This gets the pound of each item

   pd = float(input("Pound: "+str(i+1)+": "))

If price and pound are not 0

   if pr != 0 and pd != 0:

The inputs are appended to their respective lists

       prices.append(pr)

       pounds.append(pd)

If otherwise, the loop is exited

   else:

       break

This initializes total to 0

amount = 0

This iterates through all inputs

for i in range(len(pounds)):

This multiplies each pound and each price and sum them up

   amount+= (pounds[i]*prices[i])

The total is then printed

print("Amount: $",amount)

Create a public class called Exceptioner that provides one static method exceptionable. exceptionable accepts a single int as a parameter. You should assert that the int is between 0 and 3, inclusive.
If the int is 0, you should return an IllegalStateException. If it's 1, you should return a NullPointerException. If it's 2, you should return a ArithmeticException. And if it's 3, you should return a IllegalArgumentException.

   public static void exceptionable(int number){

      //check if number is 0.

       if(number == 0) {

           //if it is 0, return an IllegalStateException

           throw new IllegalStateException("number is 0");

what is the role of computer in modern problem solving​

Answers

Answer:

Una computadora es una herramienta muy básica para hacer tareas repetitivas de forma más eficiente. Una computadora no es capaz de analizar un problema y obtener una solución.

Explanation:

You are responsible for a rail convoy of goods consisting of several boxcars. You start the train and after a few minutes you realize that some boxcars are overloaded and weigh too heavily on the rails while others are dangerously light. So you decide to stop the train and spread the weight more evenly so that all the boxcars have exactly the same weight (without changing the total weight). For that you write a program which helps you in the distribution of the weight.
Your program should first read the number of cars to be weighed (integer) followed by the weights of the cars (doubles). Then your program should calculate and display how much weight to add or subtract from each car such that every car has the same weight. The total weight of all of the cars should not change. These additions and subtractions of weights should be displayed with one decimal place. You may assume that there are no more than 50 boxcars.
Example 1
In this example, there are 5 boxcars with different weights summing to 110.0. The ouput shows that we are modifying all the boxcars so that they each carry a weight of 22.0 (which makes a total of 110.0 for the entire train). So we remove 18.0 for the first boxcar, we add 10.0 for the second, we add 2.0 for the third, etc.
Input

Answer:

The program in C++ is as follows:

#include <iostream>

#include <iomanip>

   int cars;

   cin>>cars;

   double weights[cars];

   double total = 0;

   for(int i = 0; i<cars;i++){

       cin>>weights[i];

       total+=weights[i];    }

   double avg = total/cars;

   for(int i = 0; i<cars;i++){

       cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl;    }

   return 0;

}

Explanation:

This declares the number of cars as integers

   int cars;

This gets input for the number of cars

   cin>>cars;

This declares the weight of the cars as an array of double datatype

   double weights[cars];

This initializes the total weights to 0

   double total = 0;

This iterates through the number of cars

   for(int i = 0; i<cars;i++){

This gets input for each weight

       cin>>weights[i];

This adds up the total weight

       total+=weights[i];    }

This calculates the average weights

   double avg = total/cars;

This iterates through the number of cars

   for(int i = 0; i<cars;i++){

This prints how much weight to be added or subtracted

       cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl;    }

Explanation:

The correct answer is - once per month

Reason -
