Chapter 1, Problem 27E
Explanation of Solution
Given:Â The details of three students:
Snow White, student ID: A00234, credits: 24
Lisa Simpson, student ID: C22044, credits: 56
Charlie Brown, student ID: A12003P, credits: 6
To find:
A way to add three students.
A way to enroll them into labClass.
A way to use printlist() to print all the students of that class.
Solution:
Start BlueJ and then open a new project named lab-classes.
A new window will appear on screen in which each rectangular block will represent a class.
To create object of LabClass class, it is necessary for the user to right click on the LabClass class and then click on the new LabClass (int maxNumberOfStudents) from the pop-up menu. The parameter should be filled and the user can provide a specific name of instance and then click ok button.
A new red rectangle will appear at the bottom of the BlueJ screen labeled with the name of instance provided by the user.
To create object of Student class, it is necessary for the user to right click on the Student class and then click on the new Student (String fullName, String studentID) from the pop-up menu...

Create three students with the following details: Snow White, student ID: A00234,credits: 24 Lisa Simpson, student ID: C22044,credits: 56 Charlie Brown, student ID: A12003,credits: 6 Then enter all three into a lab and print a list to the screen.
Create a list that contains 10 words and their descriptions. Your task is to have the application randomly select a word from the list and display the description to the user. User will then try to guess the word based on the clue displayed. One round of game is five chances. Once the total number of chances becomes zero, the program should prompt the user whether to keep playing or exit the application.
Question-2:
You work at an IT company, and you have been asked to design a simple
chatbot that takes orders. The chatbot will keep asking for an item and its
quantity until the customer types “Complete". Then, it will set a price for
each item depending on the length of the item's name and multiplying it
with the quantity. Finally, it will print the whole list with the
individual prices and summed prices, and finally, print the total amount.
If no item was added, print "Nothing in the list".
Hint: Use a dictionary to save the items and their quantities.
Sample Input 1:
Please enter item 1: Apple
Please enter the quantity: 3
Please enter item 2: Orange
Please enter the quantity: 4
Please enter item 3: Complete
Sample output 1:
The complete list is:
Apple - 5 - 15
Orange - 6 - 24
{'Apple': [5, 15], 'Orange': [6, 24]}
Total price = 39

- switch_player(): we will allow the players to choose their own names, but for our purposes, it is easier to think of them as number (0 and 1, for indexing purposes). We will display their names to them on the screen, but in the background, we will keep track of them based on their number. This function should take 1 argument, an integer (either 0 or 1) representing the player and should return the opposite integer (1 if 0 is entered and 0 if 1 is entered). This is a simple function, but it will make our code cleaner later. Use your constants! Using Thonnyarrow_forwardComplete the following code as instructed in the line comments.

- Extra 7-2 Add a stopwatch to the Clock application In this exercise, you’ll add a stopwatch feature to a digital clock application. The stopwatch will display elapsed minutes, seconds, and milliseconds. 1. Open the application in this folder: exercises_extra\ch07\clock_stopwatch\ 2. In the JavaScript file, note the $(), displayCurrentTime(), padSingleDigit(), and DOMContentLoaded event handler functions from the Clock application. In addition, note the global variables and starting code for the tickStopwatch(), startStopwatch(), stopStopwatch(), and resetStopwatch() functions. 3. In the tickStopwatch() function, add code that adds 10 milliseconds to the elapsedMilliseconds variable and then adjusts the elapsedMinutes and elapsedSeconds variables accordingly. Then, add code that displays the result in the appropriate span tags in the page. 4. In the startStopwatch() function, add code that starts the stopwatch. Be sure to cancel the default action of the link too. 5. In the…arrow_forwardQ3: Lecture Hall Dan holds his CSC108 lectures in a rectangular N X M lecture hall. In other words, this lecture hall has N rows of seats, each of them containing exactly M seats. Here's my attempt at drawing this layout when N = 3 and M = 5: Dan Off 00 lecture hall layout with 3 rows and 5 seats per row The rows are numbered from 1 to N starting from the front row. Similarly, the columns are numbered from 1 to M starting from the leftmost column. We write (r, c) to denote the c-th seat in the r-th row. When Dan walks into the lecture hall this morning, some of the seats are already taken (this is the initial layout of the lecture hall). After that, the students come in one group at a time. From experience, Dan knows that when a group of K students enter the lecture hall, they look for K consecutive empty seats. That is, they try to find an empty seat (r, c) such that for all integers i in [0, K-1], the seat (r, c + 1) exists and is empty. If they can't find K consecutive empty seats,…arrow_forwardExtra 6-1 Develop the Temperature Converter In this exercise, you’ll use radio buttons to determine whether the conversion is from Fahrenheit to Celsius or vice versa. You’ll also modify the DOM so the labels change when a radio button is clicked, and the page displays an error message when the user enters invalid data. 1. Open the application in this folder: exercises_extrach06convert_temps 2. Note that the JavaScript file has some starting JavaScript code, including the $() function, three helper functions, three event handler functions, and a DOMContentLoaded event handler that attaches the three event handlers. 3. Review how the toCelsius() and toFarhenheit() event handler functions call the toggleDisplay() helper function and pass it strings to display. Also note that the toggleDisplay() helper function and the convertTemp() event handler function are incomplete. 4.
