The Delicious class – iterative methods The Delicious class must:• Define a method called setDetails which has the following header: public void setDetails(String name, int price, boolean available) This must find in the ArrayList the Chicken with the given name, change itspricePerKilo to the given price parameter and set whether it is in stock or not. A value of true for the available parameter means the chicken is in stock and a value of false means it is sold out (not in stock). Note that there will only be at most one Chicken object of the given name stored in the ArrayList.• Define a method called removeChicken that takes a single String parameter representing a chicken’s name. This method must remove from the ArrayList the Chicken object (if any) with the given name. The method must return true if a cheese with the given name was found and removed, and false otherwise.The Delicious class – challenge method In the Delicious class complete the findClosestAvailable method: This…
2. A pentagonal number is defined as n(3n-1)/2 for n = 1, 2, ..., etc.. Therefore, the first few numbers are 1, 5, 12, 22, ... . Write a method with the following header that returns a pentagonal number: %3D public static int getPentagonalNumber(int n) For example, getPentagonalNumber(1) returns 1 and getPentagonalNumber(2) returns 5. Write a test program that uses this method to display the first 100 pentagonal numbers with 10 numbers on each line. Numbers are separated by exactly one space.
PART B Write the following three methods and include in the Part D code listing: public int GetRandomUniform(int min, int max) This method returns a random number from a uniform distribution between min and max. public double GetRandomNormal(double mean, double stddev) This method returns a random number from a normal distribution with a mean of mean and standard deviation of stddev public int GetBinIndex(double mini, double maxi, int numbins, double valuetobin) This method returns the Bin Index given an input minimum of mini, input maximum of maxi, numbins number of bins, and a value to bin of valuetobin PART C Include the methods created in part B to develop a Visual C# .NET program that will simulate the basic profit calculation, PT = nPv, where n follows a uniform distribution, P, follows a normal distribution, and the user can input the number of bins and number of iterations. The user must also input the min and max for n and the mean and standard deviation for Py. Finally, the…
