Explain in your own words how and why final variables are used. Illustrate your answer using the code below, explaining how it could be improved by the introduction of final variables. This code is intended to print the areas of 100 circles whose radius is input. The function, inputlnt, returns an integer input by the user. Note you are not required to explain or trace this code, just use it to illustrate points you make about final variables. public static void circles () { for (int i = 1; i <= 100; i ++) { int radius inputInt("What is the radius?"); = 3.14 * radius * radius; double area System.out.println(area); }

Python question please include all steps and screenshot of code. Also please provide a docstring, and comments throughout the code, and test the given examples below. Thanks. Implement function heads() that takes no input and simulates a sequence of coin flips.The simulation should continue as long as 'HEAD' is flipped. When the outcome of a flipis 'TAIL', the function should return the number of 'HEAD' flips made up to that point.For example, if the simulation results in outcomes 'HEAD', 'HEAD', 'HEAD', 'TAIL', thefunction should return 3. NOTE: Recall that random.choice(['HEAD', 'TAIL']) returns'HEAD' or 'TAIL' with equal probability.>>> heads()0 # TAIL is the outcome of the first coin flip>>> heads()2 # The coin flips were HEAD, HEAD, TAIL>>> heads()1 # The coin flips were HEAD, TAIL>>> heads()5 # The coin flips were HEAD, HEAD, HEAD, HEAD, HEAD, TAIL
hi! i am a newbie in python. please help me on this problem. also, please send a screenshot for a proof that the codes works. thanks~
kindly change the program following the procedure on the problem. please list the changes you have made on the program t..thank you
Not copy. Giving wrong solutions. In all attempt. Downvote
Correct answer will be upvoted else downvoted. Computer science. You are given a positive integer x. Check whether the number x is representable as the amount of the solid shapes of two positive integers. Officially, you really want to check in case there are two integers an and b (1≤a,b) to such an extent that a3+b3=x. For instance, in the event that x=35, the numbers a=2 and b=3 are reasonable (23+33=8+27=35). In the event that x=4, no pair of numbers an and b is reasonable. Input The primary line contains one integer t (1≤t≤100) — the number of experiments. Then, at that point, t experiments follow. Each experiment contains one integer x (1≤x≤1012). Kindly note, that the input for some experiments will not squeeze into 32-cycle integer type, so you should use something like 64-bit integer type in your programming language. Output For each experiment, output on a different line: "Indeed" in case x is representable as the amount of the 3D shapes of two…

9. answer previous chapters, you continued to modify the MarshallsRevenue program. Now, modify the program so that the major functions appear in the following individual methods: GetMonth - This method prompts for and returns the month GetNumMurals - This method prompts for and returns the number of murals scheduled and is called twice -- once for interior murals and once for exterior murals ComputeRevenue - This method accepts the number of interior and exterior murals scheduled, accepts the month they are scheduled, displays the interior and exterior prices, and then returns the total expected revenue DataEntry - This method fills an array with customer names and mural codes and is called twice -- once to fill the array of interior murals and once to fill the array of exterior murals GetSelectedMurals - This method continuously prompts for mural codes and displays jobs of the corresponding type until a sentinel value is entered. using System; using static System.Console; using…
Do not use regular expressions in your solution for this exercise. Write a program that checks to see if an input password is valid or not. In this exercise, a valid password has the following characteristics: It contains at least eight characters. It contains at most 12 characters. It contains only alphabetic characters, digits and the underscore (‘_’) character. It does not start with a digit. It has a mix of upper-case and lower-case characters. Your class must contain the following method: public static String checkPassword(String input) This method receives a possible password as input and returns only the String“OK” if the password is valid. If the password is not valid then you can return the reason(s) for that as the return value. This is not a part of the requirements, however, and you don’t need to do that. You can simply return null for an invalid password.
Hi, I need help with the following assignment. Implement a program that reads in a year and outputs the approximate value of a Ferrari 250 GTO in that year. Use the following table that describes the estimated value of a GTO at different times since 1962. Year Value 1962-1964 $18,500 1965-1968 $6,000 1969-1971 $12,000 1972-1975 $48,000 1976-1980 $200,000 1981-1985 $650,000 1986-2012 $35,000,000 2013-2014 $52,000,000
You are responsible for adding the appropriate testing code to your main. a. The getValedictorian method returns the valedictorian of the class, that is the student with the highest grade point average. Implement this new method. b. The getHonorsPercent method returns the percentage of students in the class who are in the honors program. Use 3.75 as the cutoff GPA. Implement this method. Also print the list of students, by using the isHonor method, in the Honors program. c. An alternate implementation for the School class is being considered, in which the students are stored in an ArrayList instead of an array. Show how the declaration of the data field students would look in this alternate design. MAIN CLASS: import java.util.ArrayList; public class Main { public static void main(String[] args) { System.out.println("Unit07Project2 by Your Name"); System.out.println(); int size = 10; School onw = new School(size); /* Add the code…
Implement the following questions using Python. Make use of conditional and print statements.Make sure to clearly define your variables and don’t forget to indent your code. The logician Raymond Smulyan describes an island containing two types of people:knights who always tell the truth and knaves who always lie. You visit the island and are approached bytwo natives who speak to you as follows:• A says: B is a knight.• B says: A and I are of opposite type.What are A and B?
Use only switch and if statements only, please.
