Task 03: Read the concept of Binomial coefficient given in chapter-6. Write a method that takes two parameters n and k and returns the value of Binomial Coefficient C(n, k). For example, your function should return 20 for n = 6 and k = 3, and it should return 35 for n= 7 and k = 4. (confirm it through the Pascal's triangle as given below). 1 1 1 2 1 1 3 3 1 14 6 4 1 15 10 10 5 1 15 (20 15 6 1 1 7 21 35 (35 21 7 1 1

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.

Create a class with a method. The method has to decide whether a given year is a leap year or not. Note- A year is a leap year if: • It has an extra day i.e. 366 instead of 365. It occurs in every 4 year e.g. 2008, 2012 are leap years. For every 100 years a special rule applies-1900 is not a leap year but 2000 is a leap year. In those cases, we need to check whether it is divisible by 400 or not. > > ClassAssignmentEx2 ©LeapYearDecider javaclassnotes.assignments javaclassnotes.assignments ClassAssignmentEx2() LeapYearDecider() main(String):void A isLeapYear(int):boolean

Question 2 Write a method int countMultiplesofFive (int x, int y) that returns the number of multiples of 5 bounded between x and y inclusive. In the main, ask the user to enter two positive numbers (both must be positive, if users enter a negative value, they keep reentering values until both numbers are positive). Use the method countMultiplesofFive to find and print how many multiples of 5 exists between the two entered numbers inclusive. Sample run 1: First random: 11 Second random: 80 There are 14 umber that are multiple of five between 11 and 80 Sample run 2: First random: 75 Second random: 33 There are 9 number that are multiple of five between 33 and 75
We will rewrite the Sales Bar Chart question to use method for printing out the bar chart. The part where the asterisks are printed out should be done with a method. Use this method for each bar. The original question statement is here: Write a program that asks the user to enter today’s sales for five stores. The program should display a bar chart comparing each store’s sales. Create each bar in the bar chart by displaying a row of asterisks. Each asterisk should represent $100 of sales. Here is an example of the program’s output: Enter today's sales for store 1: 1000 [Enter] Enter today's sales for store 2: 1200 [Enter] Enter today's sales for store 3: 1800 [Enter] Enter today's sales for store 4: 800 [Enter] Enter today's sales for store 5: 1900 [Enter] SALES BAR CHART Store 1: ********** Store 2: ************ Store 3: ****************** Store 4: ******** Store 5: *******************
1. Write the following method that returns the intersecting point between two lines (p1, p2) and (p3, p4): public static Point 2D getIntersecting Point ( Point 2D pl, Point 2D p2, Point 2D p3, Point2D p4); The method returns null if the two lines are parallel. Write a test program that prompts the user to enter three points and displays the center point. Here is a sample run. (Hint: for finding the intersecting point between two lines, see Programming Exercise 8.31.) Enter x1, yl, x2, y2, x3, y3, x4, y4: 225 -1.0 4.0 2.0 -1.0 -2.0 The intersecting point is at (2.88889, 1.1111) The two lines are parallel
Write a Java program that asks the user to enter a string and counts how many times the letter "s" or "S" appears in the string. Display that number and then display the string that many times. Requirements: Call a method that gets the string from the user. Use recursion to ensure the string has at least 5 characters. Call a method that returns the number of times the letter "s" or "S" appears in the string. This method should use recursion. Call a method that takes the number of times the letter"s" or "S" appeared in the string and display the original string that was obtained from the user that many times using recursion. Call a method that sorts the letters in the string and searches for the letter "m". Display Found or Not Found.
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…
We discussed and did an example of the Quadratic formula in class. Here is the code for the method that I used in that example below. Implement this method in your program. (I suggest your base your Quadratic method on my example from Chapter 8). Modify my method to return 0 for both results and set blnValidEquation to false if the entered values do not have a solution. HINT: If the expression in the square root evaluates to a negative number, there is no valid solution. I gave some pretty strong hints to this one during the lecture. class Program{static void Main(string[] args){double dblA, dblB, dblC;double dblR1, dblR2;Console.WriteLine("Equation format: ax^2 + bx + c = 0");Console.Write("Enter value for a: ");dblA = double.Parse(Console.ReadLine());Console.Write("Enter value for b: ");dblB = double.Parse(Console.ReadLine());Console.Write("Enter value for c: ");dblC = double.Parse(Console.ReadLine());//Quadratic(dblA, dblB, dblC, out dblR1, out dblR2);if (Quadratic(dblA, dblB,…

Assume that you are not able to perform other operations on an int value thanto decrement it and compare it with zero and one. Write two methods odd(int x)and even(int x) that respectively return if x is odd or even. We assume thatx >= 0.
Java Script There is a single operator in JavaScript, capable of providing the remainder of a division operation. Two numbers are passed as parameters. The first parameter divided by the second parameter will have a remainder, possibly zero. Return that value. Examples remainder(1, 3) → 1 remainder(3, 4) → 3 remainder(-9, 45) → -9 remainder(5, 5) → 0 Notes The tests only use positive and negative integers. Don't forget to return the result.
