Take the following list of methods: Student () { // Creates a student object with all fields blank } Student (String name) { // Creates a student object with a set name } Student (String name, Array []) { } power (int x) { // returns x^2 } power (int x, int y) { // returns x^y } greet (String name) { // returns "Hello, " + name + "!"; } a) What are your options if you want to find the value of a number squared? Which would you choose if you wanted the method to say something to the user? b) What 'Student' would you call if you want to create a student when you don't have any input? c) What 'Student' would you call if you had a whole array of data to input into the student object? d) Why do you think this is a capability that Java has? What uses can you imagine for it?

In java Write a class with a main() method. The main() method should declare and initialize four different ArrayLists, each containing at least four int values. The class should also contain a method named fiveEight. Given an ArrayList of ints, the fiveEight should return the int 30 if every element of the given ArrayList is either a 5 or a 8; otherwise, it should return -9. There should be four calls to the allfiveEight method in the main() method.
class TenNums {private: int *p; public: TenNums() { p = new int[10]; for (int i = 0; i < 10; i++) p[i] = i; } void display() { for (int i = 0; i < 10; i++) cout << p[i] << " "; }};int main() { TenNums a; a.display(); TenNums b = a; b.display(); return 0;} Continuing from Question 4, let's say I added the following overloaded operator method to the class. Which statement will invoke this method? TenNums TenNums::operator+(const TenNums& b) { TenNums o; for (int i = 0; i < 10; i++) o.p[i] = p[i] + b.p [i]; return o;} Group of answer choices TenNums a; TenNums b = a; TenNums c = a + b; TenNums c = a.add(b);

Method Details getCountInRange public static int getCountInRange(int[] array, int lower, int upper) Returns the number of values in the range defined by lower (inclusive) and upper (inclusive) Parameters: array - integer array lower - lower limit upper - upper limit Returns: Number of values found Throws: java.lang.IllegalArgumentException - if array is null or lower is greater than upper Any error message is fine (e.g., "Invalid parameters(s)")
Write code for PersonManagement class. This class contains the array of Person class (code is given below) and also following methods: set: This method receives the array of person class and set the attribute. displayAll: This method will display values of all persons. sort: This method will sort the array according to age values of the persons with ascending order using Selection Sort. reverse: This method will reverse the order of the array. getPersons: This method will return the array of the persons (attribute). displayEvenAgePerson: This method will display all those persons values who have even age. displayOddAgePerson: This method will display all those persons values who have odd age. displayPrimeAgePerson: This method will display only those persons values who have prime number age. Following is the class of Person: public class Person { private String Name; public int age; public void set(String Name, int age) { this.Name =…

Recipe Program - Java ONLYI am looking to create a program that is a recipe holder. It needs to include at a minimum: At least 1 loop An Array or ArrayList At least 3 Java classes Use of methods The program would allow the user to (as part of a menu selection): Add a recipe Include ingredient list Instructions List all recipes that are in the program (array) Display a single recipe Search Recipes (option to view recipe selected) For example, searching for peanut butter cookie would bring up the recipe or multiple if the same name. The user could then select one of them to view the recipe. Search Recipes with a single ingredient (option to view recipe selected) For example: search for coconut and it would bring up coconut cream pie and German chocolate cake. The user could then select one of them to view the recipe. Close application Also need the program in a UML diagram.
