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.

- C# Create class IntegerSet. Each IntegerSet object can hold integers in the range 0–100. The set is represented by an array of bools. Array element a[i] is true if integer i is in the set. Array element a[j] is false if integer j is not in the set. The parameterless constructor initializes the array to the “empty set” (i.e., a set whose array representation contains all false values.) • Provide the following methods: a) Method Union creates a third set that’s the set-theoretic union of two existing sets (i.e., an element of the third set’s array is set to true if that element is true in either or both of the existing sets—otherwise, the element of the third set is set to false). b) Method Intersection creates a third set which is the set-theoretic intersection of two existing sets (i.e., an element of the third set’s array is set to false if that element is false in either or both of the existing sets—otherwise, the element of the third set is set to true). c) Method…Create class IntegerSet. Each IntegerSet object can hold integers 0 though n, where n can be different for different sets. The set is represented by an array of booleans. Array element a[i] is true if integer i is in the set. Array element a[j] is false if integer j is not in the set. Provide the following methods. Constructor IntegerSet(int n) creates an object with an array of size n with all cells set to false. Method union(IntegerSet set) creates a set that is the set-theoretic union of two existing sets (i.e., an element of the new set’s array is set to true if that element is true in at least one of the existing sets – otherwise, the new set’s element is set to false). Method intersection(IntegerSet set) creates a set which is the set-theoretic intersection of two existing sets (i.e., an element of the new set’s array is set to false if that element is false in at least one of the existing sets – otherwise, the new set’s element is set to true).

- TaskDeclare and implement 5 classes: FloatArray, SortedArray,FrontArray, PositiveArray & NegativeArray.1- The FloatArray class stores a dynamic array of floats and itssize. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the end of the array.- Overloading for the insertion operator << to write the array to afile (ofstream)- Overloading for the extraction operator >> to read the arrayelements from the file (ifstream) and add them to the array.- A destructor to deallocate the array2- The SortedArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the right place in the arraysuch that the array remains sorted with every add. Don’t add tothe array then sort but rather add in the right place.3- The FrontArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the front of…****************************Instructions***************************** Add a "copy constructor" to your dynamic-array student.

You may only use one auxiliary method. The method should create an ArrayList that is passed to the auxiliary in order to place the indices (if any). If no indices are found, an empty (size of 0) ArrayList will be returned. You can assume the array parameter will not be null and every row of the two-dimensional array has an array with a size of at least 0. Your implementation must be recursive and you may not use any loop construct. Do not use ++ or -- in any recursive call argument. It may lead to an infinite recursion. For example, use index + 1, instead of index++. Parameters: array - rowLength - Returns: ArrayList<Integer>
- //Need help fixing some issues with a project. PLEASE read below Write a Java program that implements both Linear Search and Binary Search. The program will take a collection of objects (generic type data) as input and print the number of comparisons needed to find a target element within that collection. You will create the following two Java classes:1. SearchCombo.java : Code for both linearSearch and binarySearch will be in this class. You may take help from the textbook Chapter 9, Section 9.1. However, note that the design requirements are different from the textbook code.•Both search methods must use the Comparable<T> interface and the compareTo() method.•Your program must be able to handle different data types, i.e., use generics.•For binarySearch, if you decide to use a midpoint computation formula that is different from the textbook, explain that formula briefly as a comment within your code. 2.

The method replaces each oldVal element in the array with newVal. Make sure to include the method header.Use the ArrayList class Add and remove objects from an ArrayList Protect from index errors when removing Practice with input loop Details: This homework is for you to get practice adding and removing objects from an ArrayList. The Voter class was used to create instances of Voters which held their name and a voter identification number as instance variables, and the number of instances created as a static variable. This was the class diagram: The constructor takes a string, passed to the parameter n, which is the name of the voter and which should be assigned to the name instance variable. Every time a new voter is created, the static variable nVoters should be incremented. Also, every time a new voter is created, a new voterID should be constructed by concatenating the string “HI” with the value of nVoters and the length of the name. For example, if the second voter is named “Clark Kent”, then the voterID should be “HI210” because 2 is the value of nVoters and 10 is the number…

For instance, if you added the Strings "one", "two", "three" in that order, code the SinglyLinkedList print() method to display "one two three". You can do this by recursively traversing the list, then displaying each item as you return from each activation record. For instance, data "one two" should be displayed as "two one".package circularlinkedlist;import java.util.Iterator; public class CircularLinkedList<E> implements Iterable<E> { // Your variablesNode<E> head;Node<E> tail;int size; // BE SURE TO KEEP TRACK OF THE SIZE // implement this constructorpublic CircularLinkedList() {} // I highly recommend using this helper method// Return Node<E> found at the specified index// be sure to handle out of bounds casesprivate Node<E> getNode(int index ) { return null;} // attach a node to the end of the listpublic boolean add(E item) {this.add(size,item);return false; } // Cases to handle// out of bounds// adding to empty list// adding to front// adding to "end"// adding anywhere else// REMEMBER TO INCREMENT THE SIZEpublic void add(int index, E item){ } // remove must handle the following cases// out of bounds// removing the only thing in the list// removing the first thing in the list (need to adjust the last thing in the list to point to the beginning)// removing the last…
