We need to implement equals() method inside the Employee class
When we are going to search, we need to compare two Employee objects, so the equals() method should definetly be inside the Employee class, we will call/invoke the equals() method on an employee object passing another emplyee object to the equals() method.
Add Answer to:
Suppose that we have the following three classes: LL<T>, Node<T>, Employee Where should the equals method...

if we have following List classes: public class LinkedList<T> { class ListNode { protected T value; protected ListNode next; public ListNode(T val, ListNode nxt) { value = val; next = nxt; } public ListNode(T val) { this(val, null); } public ListNode() { this(null, null); } } can you write the folowing methods in java: 1.Write a method for the LinkedList class called int indexOf(T val) which returns the integer index indicating the location of val in the list, or -1...

Suppose we have the following Java Interface: public interface Measurable { double getMeasure(); // An abstract method static double average(Measurable[] objects) { // A static method double sum = 0; for (Measurable obj : objects) { sum = sum + obj.getMeasure(); } if (objects.length > 0) { return sum / objects.length; } else { return 0; } } } Write a class, called Person, that has two instance variables, name (as...

In this assignment you are to utilize the Node data structure provided on Blackboard. In this assignmet you are to write a main program that implements two methods and a main method as their driver. So, only main and two methods with it. Note: You may not use any of the LinkedList class provided on Blackboard, you may use the methods in it as a guide (you should actually look at them) but you cannot use any of the methods...

In this assignment, you will add several methods to the Binary Search Tree. You should have completed the following three methods in the lab: public void insert(Key key, Value value) public Value get(Key key) public void inorder(Node root) For this assignment, you will implement the following: public void remove(Node root, Key key) public Key getMin(Node n) public Key getMax(Node n) public int height(Node n) The main method contains the statements to check whether your implementation works. You need to change...

Data Structures - Singly Linked Lists You will add a method swapNodes to SinglyLinkedList class (below). This method should swap two nodes node1 and node2 (and not just their contents) given references only to node1 and node2. The new method should check if node1 and node2 are the same node, etc. Write the main method to test the swapNodes method. You may need to traverse the list. package linkedlists; public class SinglyLinkedList<E> implements Cloneable { // ---------------- nested Node class...

(1 point) Suppose we have ut = aʻuzz, 0 < x <1,t > 0, boundary conditions are u(0,t) = u(1,t) = 0, and the initial condition is u(x,0) = sin(T2). What will be the behavior of u(x, t) as time increases. There may be more than one correct answer. You do not need to solve the equation to answer this question. A. The solution behaves unpredictably. B. The solution increases to infinity. OC. For a fixed t, the solution will...

Write the following method definitions for the DLL class:
(5 pt) void push(string t, string a, int m, int s);
This pushes a new node onto the end of
the list. If there are no nodes in the list, it creates the first
node and adds it. Otherwise it places a new node onto the end of
the list. t is the song’s title,a is the song’s artist, m is the
number of minutes the song runs for, and s...

Create the following classes: DatabaseType: an interface that contains one method 1. Comparator getComparatorByTrait(String trait) where Comparator is an interface in java.util. Database: a class that limits the types it can store to DatabaseTypes. The database will store the data in nodes, just like a linked list. The database will also let the user create an index for the database. An index is a sorted array (or in our case, a sorted ArrayList) of the data so that searches...
