good afternoon could you help me by modifying a code with a nicer interface and showing me lines of fields but please modify it yourself.
Write down what is the purpose of the following code. What each line/command of the code states.
Add another public method called add() to TestFraction1 class. This method adds another fraction to the ‘calling object’. Thus, the method will take a Fraction class object as a parameter, add this parameter fraction to the calling object (fraction), and return a Fraction object as a result. HINT: we can use cross multiplication to determine the numerator of the resultant Fraction. The denominator of the resultant Fraction is simply the multiplication of the denominators of the two other Fractions. import java.util.Scanner;//test programpublic class TestFraction1{public static void main(String[] args) {//create a Scanner objectScanner in = new Scanner(System.in);//create new fractionFraction frac = new Fraction();//declare numerator and denominatorint n=1,d;System.out.print("Enter Fraction's Numerator: ");//input numeratorn = in.nextInt();System.out.print("Enter Fraction's Denominator: ");//input denominatord = in.nextInt();//loop execute until the numerator is…
Answer the given question with a proper explanation and step-by-step solution. Write a method that takes in an array of Point2D objects, and then analyzes the dataset to find points that are close together. Be sure to review the Point2D API. In your method, if the distance between any pair of points is less than 10, display the distance and the (x,y)s of each point. For example, "The distance between (3,5) and (8,9) is 6.40312." The complete API for the Point2D ADT may be viewed at http://www.ime.usp.br/~pf/sedgewick-wayne/algs4/documentation/Point2D.htmlLinks to an external site.. Do not compare a point to itself! Try to write your program directly from the API - do not review the ADT's source code. (Don't worry too much about your answer compiling - focus on using an API from its documentation.) Your answer should include only the method you wrote, do not write a complete program.

Extend the functionality of the Carinventory class by introducing a new method called 'add_car. This method should facilitate the addition of custom cars to the inventory. The method should take two parameters: a car model and its price. Implement this method to ensure that the inventory is updated accordingly. Instantiate a new object of the car inventory, naming it 'Auto Emporium,' utilizing the extended class with the newly added 'add_car' method. Your next step is to add three distinct custom cars to 'AutoEmporium'-for example, "Sleek Sedan,' 'Sporty Convertible,' and 'Luxury SUV: Assign varying prices to each of these cars. To conclude, utilize the 'display_inventory method to showcase the updated information about 'AutoEmporium." Verify that the output includes details about the newly added custom cars, ensuring that the prices are accurately reflected. This question tests the candidate's ability to implement a specific method, instantiate objects, add custom items, and…
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.

I need to change my doubles into regular ints in the start and then convert them during the getWinPercentage(). I'm not sure where to put it.
Could you add functions (def) to the code. You can change the code but the output must be the same. Please write your OWN code and attach the picture. Thanks!
I have a Programming Question, The following is a class definition for a simple Ebook. So i need to write a second constructor that takes a String array of pages as input and sets the String array instance variable equal to the input. Continue to default the current page number to zero. Part 2: Write a getter and a setter method for the page number variable. The setter should check to make sure that the input is a valid page number and only update the variable if the new value is valid. Part 3: Write a getCurrentPage method that returns the String of the current page indexed by current_page. Here below are the two instance variables and one parameterless constructor that were provided public class Ebook{ private String[] pages; private int current_page; //constructor public Ebook() { this.pages = {"See Spot.", "See Spot run.", "Run, Spot, run."}; this.current_page = 0; }}
