- 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.[JAVA] Please provide comments to my code import java.util.HashMap;public class Items {private final HashMap<String, Integer> allWeapons = setHash("weapon");private final HashMap<String, Integer> allArmor = setHash("armor");private final HashMap<String, Integer> allConsumables = setHash("consumable");public String type;public String name;public int modifier;public Items(String type) {randomItem(type);}public Items(String type, String name) {switch (type) {case "weapon":if (allWeapons.containsKey(name)) {this.type = "weapon";this.name = name;this.modifier = allWeapons.get(name);} else {randomItem(type);}break;case "armor":if (allArmor.containsKey(name)) {this.type = "armor";this.name = name;this.modifier = allArmor.get(name);} else {randomItem(type);}break;case "consumable":if (allConsumables.containsKey(name)) {this.type = "consumable";this.name = name;this.modifier = allConsumables.get(name);} else {randomItem(type);}break;default:randomItem(type);break;}}private…In class we have used several classes that allow for iterating through data.

- 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…Create a class MapTester (either in your current project or in a new project). In it, use a HashMap to implement a contacts list similar to the one in the example above. (Remember that you must import java.util.HashMap.) In this class, implement two methods: public void enterNumber(String name, String number) and public String lookupNumber(String name) The methods should use the put and get methods of the HashMap class to implement their functionality.Java provides a mechanism that enables a program to be executed from the command line, as an application. Java runtime execution works on the basis that the class executed must have a: (constructor? inner class? method?) named `main’ that is: (final? static? local?) , public and void. This should take an : (StringBuffer? ArrayList? Array?) of Strings as its only argument. Execution is begun by (calling this method? clicking the BlueJ Run button? selecting this method from the dropdown menu?) . Select the correct answer.
- When you add a contact to your phone, it automatically sorts those names alphabetically. In this exercise, we are going to create a phonebook that automatically sorts everytime a new number is added to the phonebook. A PhoneNumber class has been created already that has the instance variables name and number. Your job is to create the PhoneBook class that will store an ArrayList of PhoneNumbers. The PhoneBook class does not have a constructor - it only contains an ArrayList that can store the individual phone numbers that are added to it. There should be three methods in the PhoneBook class: addNumber- This method takes a PhoneNumber and adds it to the directory. Once the number has been added, the sort method is called on the directory to sort that new address into the phone book. sort- This method sorts the directory in alphabetical order A-Z.a. Remember that in order to compare Strings, we can use the compareTo() method. This returns an integer that indicates whether a String’s…Below is the code for a Time class that has both an equals method and a hashCode method; however, the body of the hashCode method is missing. In the text box, write the code you would put inside the body of the hashCode method. Remember that a hashCode with no collisions is better than a hashCode that has collisions and a hashCode with no gaps in the values is better than a hashCode that has gaps. public class Time { private int hour; // A number between 1 and 12 private int min; // A number between 0 and 59 private boolean pm; // True if the time is pm. public Time(int hour, int min, boolean pm) { this.hour = hour; this .min = min; this.pm = pm; } public int getHour() { return hour; } public int getMin() { return min; } public boolean isPM() { return pm == true; } public boolean isAM() { return pm == false; } public boolean equals(Object obj) { if (this == obj) return true; if (obj ==…Below is the code for a Time class that has both an equals method and a hashCode method; however, the body of the hashCode method is missing.

- Write a main method, in which you should have an Arralylist of students, in which you should include every student. You should have a PhD student named Joe Smith. In addition, you should create an Undergraduate student object for each of your team members (setting their names). If you’re only one person doing the assignment, then you should just create one undergraduate object. For each undergraduate student, you should add add two courses (COIS 2240 and COIS 1020). Loop over the arraylist of students, print their names, if the student is an undergraduate student, print their courses.Fancy Integer ArrayList (ONLY NEED HELP WITH WRITING TEST CASES) For example, we have defined a “testRemoveInt” method for you (see below) which tests the “remove” method. Pass the tests provided then write additional tests where it says “// TODO”. You’ll do this for each unit test method in the program. import static org.junit.jupiter.api.Assertions.*; import java.util.ArrayList; import org.junit.jupiter.api.Test; class CustomIntegerArrayListTest { @Test void testSpliceIntInt() { CustomIntegerArrayList arr1 = new CustomIntegerArrayList(); arr1.add(2); arr1.add(3); arr1.add(4); arr1.add(5); arr1.add(6); arr1.splice(3, 2); ArrayList<Integer> lst1 = new ArrayList<Integer>(); lst1.add(2); lst1.add(3); lst1.add(4); assertEquals((int) lst1.get(0), (int) arr1.get(0)); assertEquals((int) lst1.get(1), (int) arr1.get(1)); assertEquals((int)…HashMap is a parameterized class. List those of its methods that depend on the types used to parameterize it. Do you think the same type could be used for both of its parameters?
