- Write a class called Pokemon that has a name (e.g. “Pikachu”) and a number (e.g. 25). Implement a constructor that takes both values as parameters. Implement accessors for both values. Implement a toString() that returns a string in the format “Name(number)”, e.g. “Pikachu(25)”. Implement an equals(Object) method (two Pokémon are considered equal if they have the same number). Implement a hashCode() method that returns the number.(remember the equals and hashCode contract).In Java, please. Complete the Course class by implementing the findStudentHighestGpa() method, which returns the Student object with the highest GPA in the course. Assume that no two students have the same highest GPA. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. (Hint: getGPA() returns a student's GPA.) Note: For testing purposes, different student values will be used. Ex. For the following students: Henry Nguyen 3.5 Brenda Stern 2.0 Lynda Robison 3.2 Sonya King 3.9 the output is: Top student: Sonya King (GPA: 3.9) LabProgram.java import java.util.Scanner; public class LabProgram { public static void main(String args[]) { Scanner scnr = new Scanner(System.in); Course course = new Course(); int…Provide a different implementation of ChoiceQuestion. Instead of storing the choices in an array list, the addChoice method should add the choice to the question text.

A. If you have an interface called Duck, and have many ducks that implement the duck interface. All of these ducks must have the behaviour “quack” but for some ducks, like a Mallard, this must result in a quack, where for a rubber duck it must result in a squeak. We decide to delegate the quack method to another interface, which can be implemented either in a concrete class that returns a quack or a concrete class that returns a squeak. B. If we have an interface called Duck. We need to give an object to a user that can quack like a duck. All we have is Turkeys. We create a special class that implements the duck interface, and to implement the quack method we simply call the turkey’s gobble method. C. None of these are like the strategy pattern. D. We have a large collection of Ducks. We want to look at them one by one and hear them quack. We write a piece of code that iterates through them all, and as we encounter…Implement a class named Parade using an ArrayList, which will manage instances of class Clown. Each Clown only needs to be identified by a String for their name. Always join a new Clown to the end of the Parade. Only the Clown at the head of the Parade (i.e., the first one) can leave the Parade. In addition, also write a method called isFront that takes a Clown as parameter and returns true if the passed clown is at the front of the parade otherwise returns false. Create a test application to demonstrate building a parade of three or four clowns and include your own name. Then, remove one or two, and add another one or two. Also, test the isFront method by passing different clowns to the method.
- Consider a scenario of Contacts Database, in which all information of user contacts will be stored. In the given scenario you have to implement your database of contacts using the Generic Arraylist you have created in Task 1.

The first, computePrimes() takes one integer input and calculates that many prime numbers.

- A FastCritter moves twice as fast as a regular critter. When asked to move by n steps, it actually moves by 2 * n steps. Implement a FastCritter subclass of Critter whose move method behaves as described. What do I need to change to make it work? import java.util.ArrayList; /** A simulated critter.*/public class Critter //superclass{ private int position; private ArrayList<String> history; /** Constructs a critter at position 0 with blank history. */ public Critter() { position = 0; history = new ArrayList<String>(); } /** Gets the history of this critter. @return the history */ public ArrayList<String> getHistory() { return history; } /** Adds to the history of this critter. @param newValue the desired state */ public void addHistory(String event) { history.add(event); } /** Gets the position of this critter. @return the position */ public int getPosition() {…Implement any one of the following methods. That will be a good exercise for you if you choose to implement both but you will be graded for only one. Implement a instance method, called equalsTo, in the IntArrayBag’s class that takes one input parameter and returns a boolean value. The input parameter is of type IntArrayBag. The method returns true if the input bag and the bag that activates the method have exactly the same elements. Otherwise the method return false. Note that the locations of the elements in the data arrays are not necessarily be the same, it is only the number of occurrences of each element that must be the same. OR Implement a static method, called equalsTo, in the IntArrayBag’s class that takes two input parameters and returns a boolean value. The input parameters are of type IntArrayBag. The method returns true if the two input bags have exactly the same elements. Otherwise the method returns false. Note that the locations of the elements in the data arrays…If a class implements the Comparable interface, it is easy to swap in/out different strategies for comparing objects of that class. For example, if our Shapes implement Comparable and provide a compareTo() that compares areas, we can provide another compareTo() override for those shapes that compares perimeter.
