write a program (its name should be StudentPoll.java) that first reads an integer, N, for the number of responses from students and then creates an array of N elements of type int to store the responses. Use SecureRandom to generate N random integers of values between 3 and 10 inclusive as the response values (i.e., the survey values) for the array. The program should print out the distribution of the survey like the following outputs. public class StudentPoll {public static void main(String[] args) {// student response array (more typically, input at runtime)int[] responses = {1, 2, 5, 4, 3, 5, 2, 1, 3, 3, 1, 4, 3, 3, 3, 2, 3, 3, 2, 14};int[] frequency = new int[6]; // array of frequency counters // for each answer, select responses element and use that value// as frequency index to determine element to increment for (int answer = 0; answer < responses.length; answer++) { try { ++frequency[responses[answer]]; } catch (ArrayIndexOutOfBoundsException e) { System.out.println(e); //…
Write the implementation of a static method, called evenElements, that takes one input parameter, called inputS, of type IntStackInterface. The method extracts all even numbers from inputS and returns as output an IntArrayStack that includes all the extracted numbers. All other odd or zero elements must remain in inputS unchanged and in the same order.
Implement Stratified sampling. Given training data, class labels and the fraction of validation data per class 'test_size'. Write a method to sample train data, test data, train labels and test labels such that each class has ‘test_size' fraction of data/labels for validation and 1-test_size fraction of data/labels for training.
Provide a different implementation of ChoiceQuestion. Instead of storing the choices in an array list, the addChoice method should add the choice to the question text. For this purpose, an addLine method has been added to the Question class. /** A question with multiple choices.*/public class ChoiceQuestion extends Question{ // Add any needed instance variables, but don't store the choices // The choices should be added to the text of the superclass /* code goes here */ /** Constructs a choice question with a given text and no choices. @param questionText the text of this question */ public ChoiceQuestion(String questionText) { /code goes here */ } /** Adds an answer choice to this question. @param choice the choice to add @param correct true if this is the correct choice, false otherwise */ public void addChoice(String choice, boolean correct) { /* code goes here */ } }
Java Computer Programming. Each robot: - Has a name (attribute name: string) - Has a position: given by the integer attributes x and y. - Has a direction: given by the direction attribute that takes one of the values "North", "East", "South" or "West". The name, position and direction of a robot are given to it at the moment of its creation - Can advance one step forward: with method without parameter advance () - Can turn right 90 ° to change direction (if its direction was "North" it becomes "East", if it was "East" it becomes "South", etc.): with the method without parameter right(). Robots cannot turn left. - Can display its detail with the method detail() Detail: name, position, and current direction.
betterAddProduct Write a method in your Warehouse class to further optimize addProduct. As of now, it’s possible that an item is removed from a full sector to make room for a new product, even if there are other sectors which are not full. If the current sector is not full, add the product as normal. Otherwise perform a linear probing-like operation to try to find a non-full sector (if the current one is full). Keep incrementing the sector until you either find one with space, or you return to your original sector. If you get to Sector 9, wrap around to Sector 0. If you found a new sector with space, add the product into this sector. In a real-world scenario we would have to make sure to change the ID in our system and make sure it doesn’t conflict with an existing one. In this assignment that is not necessary since the output only contains the name. If you returned to the original sector, perform eviction and add the product as normal.

Write the implementation of a static method called evenElements that takes one input parameter of type IntStackInterface named inputS. The procedure takes all even integers from inputS and produces an IntArrayStack containing all of the extracted values as output. All other odd or zero elements must remain in inputS unchanged and in the same order.
