- QUESTION 2 Write the overloaded method named findvAverage () for each of the following problems: a) The first method receives two integer numbers and returns the average of these two numbers b) The second method receives an array of integer numbers. Calculate and display the average of those elements in array.Write class name Student Management having array of students and count of students as attribute. There should be method for the following: Add new Student in Array Remove a Student from Array using Name (of Student) Sort the Students in array using Name (ascending order) Sort the Students in array using Age (ascending order) Sort the Students in array using CGPA (ascending order) Reverse the order of the Students in array Display information of all Students in array (from zero index to last index) Note.This is a java programUsing the new operator, allocate an integer array of user specified size (the user gives the size of the array as input). Assign values to the array elements by taking user inputs and then print the values. Finally de-allocate the arrayusing the delete operator.

- In [ ]: We obtained an array with N = 10 values, scattered about mean of 25 (mm). Let's calculate the mean, standard deviation, standard deviation of the mean and 20-uncertainty SL of these numbers. In the following code, do these steps: • In the first cell, add a brief comment that explains what each statement does. Start each comment with a # sign. • In the second cell, delete the raise Not ImplementedError() code line and print the standard deviation and 20-uncertainty on the screen (follow the example for mean_L) mean_L = np.mean (L) print("Mean length: ", mean_L) stddev_L = np. std (L, ddof=1) stddev_mean_L = stddev_L/np.sqrt(N) uncertainty_L = 2*stddev_mean_L In [ ] V #YOUR CODE HERE raise NotImplementedError() #calculates the mean of L In the above code, the green expressions on the right hand side, such as np.mean, np. std and np.sqrt are functions built into the numpy package of Python. The names on the left hand side are variable names invented by me.Complete the findMax() method that returns the largest value in array nums. Ex: If array nums contains: 2 4 6 8 10 7 5 3 the findMax() method returns: 10 Note: During development, array nums is filled with 10 pseudo-random integers in main() using the fillRandomly() method with a seed value of 7. When submitted, different seed values will be used to generate arrays of different size for the test cases. Refer to the textbook section on Random numbers to learn more about pseudo-random numbers. Code: import java.util.*;public class Numbers { private int[] nums; public int findMax() { /* Type your code here. */ } public void setNums(int[] nums) { this.nums = nums; } public int[] getNums() { return nums; } // Fill array nums with pseudo-random integers (0-999) with a seed value public void fillRandomly(int seed, int size) { Random rand = new Random(seed); nums = new int[size]; for(int i=0; i<nums.length; i++) { nums[i]…Campground reservations, part 3: Available campsites Excellent job! This next one's a little more challenging. Which campsites are available to reserve? We want to be able to quickly find which campsites are available. Can you help us? Given a campgrounds array, return an array with the campsite numbers of all currently unreserved (isReserved === false) campsites. Call the function availableCampsites. Dataset As a reminder, our data looks like this. It's an array with a bunch of campsite objects in it. Here is a small subset of the data to give you an idea: const campgrounds = [ { number: 1, view: "ocean", partySize: 8, isReserved: false }, { number: 5, view: "ocean", partySize: 4, isReserved: false }, { number: 12, view: "ocean", partySize: 4, isReserved: true }, { number: 18, view: "forest", partySize: 4, isReserved: false }, { number: 23, view: "forest", partySize: 4, isReserved: true }, ];
- Determine if the following statement are true or false Screen shot shows the text's arraycollection When comparing two objects using the == operator, what is actually compared is the contents of the objects. The equals method of the Object class returns true only if the two objects being compared have identical attributes. A collection allows retrieval of information based on the size of the information. With the text's array-based collection implementation, the set of stored elements is scattered about the array.The contents of the array below represent a maxHeap. What would be the contents of the array after a deletion. Briefly explain how the deletion is done. 60 20 30 5 10 15 25Create an indexception value of unique consonants and unique vowels.This is the Input: String of the name that was given below. It must be case sensitive.Steps:Step A: In every unique vowel of a name, you need to get the first index of that vowel from the original string.Step B: In each vowel index you get from step A, you will get the unique consonant from that position. if the index is out of scope of the consonant array, ignore that vowel index.Step C: In each unique consonant that you get from step B, you need to get the first index of that consonant from the original string.Step D: You will the value of indexception by adding all index you get from step C.output must be like this: > 2 lists that consist of unique vowels and unique consonants> vowel, the vowel index, the consonant, the consonant indexfinal ouput> total indexception value of the name that was given. ------Input "Tricia O.
