QUESTION 3 When using a dynamically allocated array for the bag, the text recommends increasing the size to double the maximum capacity of the old array. O True O False QUESTION 4 A stub is used in the development of a program or a class implementation. What is a stub? O A short program that is written to test a method An incomplete definition of a method or function. A technique for debugging your code A core method QUESTION 5 Why should you make the class's data atrributes private? O so that the class controls how a client can access or modify the data attributes so that the client controls how the class can access or modify the data attributes so that the client code cannot access or modify the data attributes so that the class has no control over how a client can access or modify the data attributes QUESTION 6 In "encapsulation", what is encapsulated? O the ADT's data and operations the ADT's accessors and mutators the data and data types in the ADT O the P's and Q's of the ADT

Image one is my file or you can create ur own file as long as it's similar to mine. image 2 is my program I want to write a 4th method(method 4) and the spec is: A method to count the occurrences of each value in an array takes one parameter, an array of integers returns an array containing the number of times each value occurs in the parameter array. Also should call method 3 from method 4Hint: The general idea of this method is using an array with length maxVal+1(maxVal should get from method 3 already) to save the occurrences of each number. For example, if number 44 occurs 3 times in the file, your array should have a value 3 stored at index 44.
In C# using an array Implement the inventory manager class. This class must have methods that do the following: Add a new item to the inventory manager. Remove an item from the inventory manager. Re-stock an item in the inventory manager. Display the items in the inventory manager. Search for an item in the inventory manager by at least two criteria (name, price, quantity, etc.). Test the inventory manager class with a driver program or unit tests. This may be a console application.

D Question 24 In Java, one can pass an array to a method using the name of the array, as in this method call: somelethod(myArray); What is the name of the method that every Java project must have that also uses an array parameter? Hint: The array parameter type and paramater name that we have been using with this method so far this semester has been: (String[ ] args).
. Create a testEmployees class. Do the following: Declare an array called arrEmp of 10 Employee type objects in the main method. Write a static method called fillArray() that receives the arrEmp array. Use a while loop to enter the information (type of contract) of a number of new employees. Quit input by entering the character X instead of the type of contract. For each employee create an object and save the object in the array. Return the array to the main method. Call the static fillArray() method from the main method. Write a static method called displayArray() to receive the array and display a numbered list of the information of the employees using a for-loop and the toString() method. Call the static displayArray() method from the main method. Write a static method called updateEmpCommission() to receive the array and update the commission of some of the employees as follows: Use a loop to update a number of employees' commission. Use a sentinel value -1 to…

Complete the following Programming Assignment. Use good programming style and all the concepts covered to date. Submit the java file(s) electronically through Canvas by the due date via one (1) Zip file. Rainfall Class - Note: Do not write a class as specified regarding the array (below). Instead use two one-dimensional arrays of size 12 each (parallel arrays) and four methods to solve the problem as specified. One array will hold the names of the months and the other array will hold the rainfall in inches for the months. You will pass the appropriate array or arrays to the methods as needed. 1. Rainfall Class Write a RainFall class that stores the total rainfall for each of 12 months into an array of doubles. The program should have methods that return the following: • the total rainfall for the year • the average monthly rainfall • the month with the most rain • the month with the least rain Demonstrate the class in a complete program. Input Validation: Do not accept negative numbers…

Please help me with this , I am stuck ! PLEASE WRITE IT IN C++ Thanks 1) bagUnion: The union of two bags is a new bag containing the combined contents of the original two bags. Design and specify a method union for the ArrayBag that returns as a new bag the union of the bag receiving the call to the method and the bag that is the method's parameter. The method signature (which should appear in the .h file and be implemented in the .cpp file is: ArrayBag<T> bagUnion(const ArrayBag<T> &otherBag) const; This method would be called in main() with: ArrayBag<int> bag1u2 = bag1.bagUnion(bag2); Note that the union of two bags might contain duplicate items. For example, if object x occurs five times in one bag and twice in another, the union of these bags contains x seven times. The union does not affect the contents of the original bags. Here is the main file: #include <cstdlib>#include <iostream>#include "ArrayBag.h"using namespace std; template…
2. write two method called findIndex and findLastIndex that search for a number in an array. they should take an int array and an int as parameters. findIndex should return the index of the first instance of the number in the array. findLastIndex should return the index of the last instance of the number in the array. They both should return -1 if the number is not found. Do not use any library methods. Sample code int a[] int x = findIndex(a,50); Sample output {10,50,30, 40,50}; 1 System.out.println(x); int a[] int x = findLastIndex (a,50); System.out.println(x); int a[] = {10,50,30,40,50}; int x = findIndex(a,70); {10,50,30,40,50}; 4 -1 System.out.println(x);
