- Write a new snowflake class that extends AbstractShape. Your snowflake should be a unique and simple shape unlike any other student’s. Use the drawing methods provided in the imported Graphics class The SimpleSnowFlake is provided in the project as an additional reference. Add an equals(Object o) method that will compare unique instance variable data and return true if two of your snowflakes are the same. Your equals method should override the method from the Object class and call the equals method of AbstractShape Your snowflake should be a different color and move in a different and unique way.arrow_forwardWrite out what you think the outer wrappers of the Student and LabClass classes might look like; do not worry about the inner part.arrow_forwardPLEASE ENSURE TO USE THE FRAMEWORK PROVIDED IN THE IMAGES, AND THAT IT WORKS WITH THE TESTER CLASS. PLEASE EDIT BOTH THE TEST CLASS, DO NOT EDIT THE MAIN METHOD. Write a BankAccountTester class whose main method constructs a bank account, deposits $1,000, withdraws $500, withdraws another $400, and then prints the remaining balance. Also print the expected result.arrow_forward
- Use the debugger to examine the clock-display project. Set breakpoints in the ClockDisplay constructor and each of the methods, and then singlestep through them. How do you feel about the way it's behaving? Have you gained any fresh insights as a result of this? If this is the case, what exactly were they?arrow_forwardCreate a test project to play with the Comparable interface. Edit the Card class to implement Comparable . Cards are to be compared using their value. They are considered the same if they have the value. One is less than the other if its value is less. Add the compareTo method that takes a Card object as a argument and returns 0 meaning the values are the same, 1 meaning the card is greater than the parameter, -1 meaning the card is less than the parameter. Create a main() that creates a Deck. Use your code from the program that dealt out Cards from a Deck and showed the hands but this time, now that Cards are comparible, show them in sorted order using Arrays.sort if the had is an array, or Collections.sort if the hand is an ArrayList. Show the hands. Document, document, document!arrow_forwardPLEASE ENSURE TO USE THE FRAMEWORK PROVIDED IN THE IMAGES, AND THAT IT WORKS WITH THE TESTER CLASS. Write a class RangeInput that allows users to enter a value within a range of values that is provided in the constructor. An example would be a temperature control switch in a car that allows inputs between 60 and 80 degrees Fahrenheit. The input control has “up” and “down” buttons. Provide up and down methods to change the current value. The initial value is the midpoint between the limits. As with the preceding exercises, use Math.min and Math.max to limit the value. Write a sample program that simulates clicks on controls for the passenger and driver seats.arrow_forward
- using eclipse part 1 Create a different package session5a. Create a class SquareDemo. Create an instance of Square in the main() method with sideLength set to 10. along with output screenshot for this part. Part 2 Create 12 Square instances in SquareDemo class with random size (1-100) and print out: If divisible by 2, print out side length If divisible by 3, print out area If divisible by 6, print out side length and area Otherwise, print out "Side length and area are hidden" along with output screenshot for this part.arrow_forwardMy code won't print out the desired test cases. For instance, the time and the event did not properly store it in the skiplistmap class, so it prints out none regardless of time and event. Also, when printing out the skiplist, it will just print out empty for each level regardless of the time and event being stored. So, can you take a look at my code and fix it? Also, how do I use a FakeRandheight class for put(k, v)? mport java.io.File;import java.io.FileNotFoundException;import java.util.Scanner;public class HW5 {public static void main(String[] args) throws FileNotFoundException {SkipListMap<Integer, String> slm = new SkipListMap<>();SkipListMap<Integer, String> cancelEvents = new SkipListMap<>();File input = new File(args[0]);Scanner in = new Scanner(input);while (in.hasNextLine()) {String line = in.nextLine();String[] parts = line.split(" ");if (parts.length == 0) {continue;}String check = parts[0];if (check.equals("AddEvent")) {if (parts.length < 3)…arrow_forwardthe answer dose not include the main method. Write a main method inside the LibraryManagementSystem class, create a menu system that allows the Librarian input commands to interact with the system. Below is the menu system that students should aim to recreate. Give an appropriate message after each action to notify the Librarian if an action was successful. Make use of the toString() to print the Book objects.arrow_forward
