Ball Class:
The Ball class inherits from Drawable and it will draw a circle at its current location. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface.
This is the Drawable Class

- 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).JAVA Create a new class HashMapManipulation with a main method. Import the necessary classes from the java.util package, including the HashMap class. Create a HashMap object, named mapand use the put() method to add key-value pairs to the map. The keys are strings "A", "B", and "C", and the values are integers 1, 2, and 3 respectively. Use the size() method to print the size of the map. Use a for loop to print the key-value pairs in the map. The loop should iterate over the entries in the map using the entrySet() method, which will return a set of Map.Entry objects representing the key-value pairs in the map. The key and value of each entry are printed using the getKey() and getValue() methods, respectively. Use theget() method to get the value of key "A", and assigns it to a variable value. The value is then printed. Use the put() method to add a new key-value pair to the map. The key is "D" and the value is 4. The map is then printed again, to show the added key-value…import java.util.ArrayList; public class Bus { privateStringname; privateintsize; privateintbasePrice; privateArrayList<Trip>approvedTrips; privateintlevel;// 1,2,3 for low,medium, high repectively; privateintid; privatestaticintnextId=0; privateMinistrymny; protectedStringtripTypes; privateintgetNextId(){ returnnextId++; } publicBus(){ approvedTrips=newArrayList<Trip>(); } publicBus(Stringname,intsize,intbasePrice,intlev,Ministrymny){ approvedTrips=newArrayList<Trip>(); this.name=name; this.size=size; this.basePrice=basePrice; this.level=lev; this.id=getNextId(); this.mny=mny; tripTypes="BASICTRANSPORT"; } publicbooleanavailable(Datedate){ booleanretval=true; for(Tript:approvedTrips) if(t.getDate().getDay()==date.getDay()) retval=false; returnretval; } publicintgetBasePrice(){ returnbasePrice; } publicintgetId(){ returnid; } publicStringgetName(){ returnname; } publicdoublegetSize(){ returnsize; } publicStringtoString(){ returnname; }…
- Import the ArrayList and List classes from the java.util package to create a list of phone numbers and also import the HashSet and Set classes from the java.util package to create a set of unique prefixes. Create a class called PhoneNumberPrefix with a main method that will contain the code to find the unique prefixes. Create a List called phoneNumbers and use the add method to add several phone numbers to the list. List<String> phoneNumbers = new ArrayList<>(); phoneNumbers.add("555-555-1234"); phoneNumbers.add("555-555-2345"); phoneNumbers.add("555-555-3456"); phoneNumbers.add("444-444-1234"); phoneNumbers.add("333-333-1234"); Create a Set called prefixes and use a for-each loop to iterate over the phoneNumbers list. For each phone number, we use the substring method to extract the first 7 characters, which represent the prefix, and add it to the prefixes set using the add method. Finally, use the println method to print the prefixes set, which will contain all of…Add a method (call it spotterAnimalArea) to AnimalLab that takes two parameters —animalType and areaID — and returns a String containing the IDs of spotters that haveseen the animal in that particular area.

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.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 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 private fields: first name, last name, and GPA. (Hint: GetGPA() returns a student's GPA.) Ex: If the following students and their GPA values are added to a course: Henry Nguyen with 3.5 GPABrenda Stern with 2.0 GPALynda Robison with 3.2 GPASonya King with 3.9 GPA then the findHighestStudent() method returns a student and the program output is: Top student: Sonya King (GPA: 3.9)Code:Course.java: import java.util.ArrayList; //create class Student //create class Courseclass Courses{ private ArrayList<Student> roster; // collection of Student object // class constructor…
- In this problem, we are going to use ArrayLists and classes to design a road trip. You have three classes: GeoLocation.java which represents a geo location. A RoadTrip.java class, which represents a road trip (or an ordered list of places), and a RoadTripTester.java class which brings them all together. In GeoLocation.java: Add a private instance variable called name which is a String. This represents the name of the location. Modify the Geolocation class constructor so that it is now of the format public GeoLocation(String name, double theLatitude, double theLongitude) Add a getter method for name called getName(). Update the toString so that it returns a String of the format San Francisco (37.7833, -122.4167) Now, you’ll also need to create a RoadTrip class. RoadTrip stores an ordered list of locations, so you’ll need to have an ArrayList as an instance variable. The RoadTrip class constructor should initialize an ArrayList that stores a list of GeoLocations. You’ll also need to…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.
