The Speed of SoundThe following table shows the approximate speed of sound in air, water, and steel:MediumSpeedAir1,100 feet per secondWater4,900 feet per secondSteel16,400 feet per secondDesign a class that stores in a distance field the distance, in feet, traveled by a sound wave.The class should have the appropriate accessor and mutator methods for this field. In addi-tion, the class should have the following methods:• getSpeedInAir. This method should return the number of seconds it would take asound wave to travel, in air, the distance stored in the distance field. The formulato calculate the amount of time it will take the sound wave to travel the specifieddistance in air is:Time = distance/1100• getSpeedInWater. This method should return the number of seconds it would take asound wave to travel, in water, the distance stored in the distance field. The formulato calculate the amount of time it will take the sound wave to travel the specifieddistance in water is:Time = distance/4900• getSpeedInSteel. This method should return the number of seconds it would take asound wave to travel, in steel, the distance stored in the distance field. The formulato calculate the amount of time it will take the sound wave to travel the specifieddistance in air is:Time = distance/16400Write a program to demonstrate the class. The program should display a menu allowing theuser to select air, water, or steel. Once the user has made a selection, he or she should beasked to enter the distance a sound wave will travel in the selected medium. Thewill then display the amount of time it will take. Check that the user has selected one ofthe available choices from the menu.programling Roints

Sammy's Seashore Supplies rents beach equipment such as kayaks, canoes, beach chairs, and umbrellas to tourists. In Chapter 3, you created a Rental class for the company. The Rental class contains two public final static fields that hold the number of minutes in an hour and the hourly rental rate ($40), and four private fields that hold a contract number, number of hours for the rental, number of minutes over an hour, and the price. It also contains two public set methods and four public get methods. Now, modify the Rental class to contain two overloaded constructors. One constructor accepts a contract number and number of minutes as parameters. Pass these values to the setContractNumber() and setHoursAndMinutes() methods, respectively. The setHoursAndMinutes() method will automatically calculate the hours, extra minutes, and price. The other constructor is a default constructor that passes "A000" and 0 to the two-parameter constructor. Save the file as Rental.java. b. In Chapter…

TODO 10 Now it's your turn to define an entire class. Complete the TODO by creating the LogTransformer class. Define the LogTransformer class by following the below steps: Create a class called LogTransformer. Make sure this class inherits BaseEstimator and TransformerMixin. Note: as we don't need the constructor method __init__() we don't have to define it. Define the fit() method. Be sure it takes the arguments self, X, and y=None just like we did above. Further, make sure to return self otherwise you will get errors. Define the transform() method which takes the arguments self, X, and y=None just like we did above. In the transform() method, return the log of the input data X. Be sure you add 1 to the data before computing the log as it is not possible to take ???(0)! # TODO 10.1 log = LogTransformer()log_area_df = log.fit_transform(forestfire_df['area'])display(log_area_df) todo_check([ (log_area_df.shape == (517,), 'log_area_df does not have the shape (517,)'),…

PLEASE FAST Define a class called Country. A Country has populationSize, area, capital, currency, and abbreviation (2-3 letters taken from the country name). Define at least two constructors, at least two getter methods, at least two setter methods, and Override the toString() and the equals() methods. The equals() method must return true if the two countries have the same name and same populationSize and false otherwise. The abbreviation is the first letter and the second letter of the country name and must be generated automatically (e.g. if the country name is Palestine the abbreviation is PA, if the country name is Jordan the abbreviation is JO.) Write a main method, define an array of country objects, read countries data from the user, if two countries have the same abbreviation add the last letter from the country name to the abbreviation of the country inserted last. Display countries whose area is greater than 10000 km2.
Create a base class called Vehicle with name, max_speed, and tank_size attributes. Then create a derived class called Truck that inherits from the Vehicle class. The Truck should have an additional attribute called seating_capacity with default value of 5. The child class should have a method named range to calculate fuel efficiency - the calculation should be: max_speed * seating_capacity * tank_size. Override the method such that it can accept 1, 2 or 3 positional arguments. Attached is my following code, also attached is a method for override method. Need help implementing the override method for the range to calculate the fuel effiency.
You are required to build a class JewelleryItem. A jewellery Item has a type (string) , price (float),material (string), daysToGo (int).These attributes represent the type i.e ‘ear ring’, necklace, finger ring etc. The material can be gold,silver, plastic etc. The daysToGo attribute represents the number of days it will remain fit for use.1. You are required to provide the following parameterized constructors JewelleryItem(string type, float price, string material, int daysToGo) Jewlleryitem(string type, float price, int daysToGo) // the material will get “gold” as default JewelleryItem(string type, float price) //the material defaults to gold and daysToGo defaults to100.2. Now provide getters for each of the attributes above but setters for only price, daysToGo3. Provide a function/method makeUse(). This function represents the use of this item for one daywhich reduces the daysToGo by 1. This function returns true if the daysToGo is greater than 1 andfalse otherwise. This means…

In the board game Scrabble, each tile contains a letter, which is used to spell words in rows and columns, and a score, which is used to determine the value of words. The point of this exercise is to practice the mechanical part of creating a new class definition: Write a definition for a class named Tile that represents Scrabble tiles. The instance variables should be a character named "letter" and an integer named "value". Write a constructor that takes parameters named letter and value, and initializes the instance variables. Create getters for both of the attributes. (No setters, so that a Tile is immutable.) Implement the .toString() and .equals methods for a Tile. Your completed Tile class should work with this Main program (Links to an external site.) so that it produces sample output like shown at the end of the program. You can Fork the program to make your own version in Replit, where you can add your Tile.java, or you can copy the program to your own Java development…
Write all the code necessary for a class Truck. A Truck can be described as having a make (string), model (string), gas tank capacity (double), and whether it has a manual transmission (or not). Include the following methods in your class definition. . An overloaded constructor which takes the make and model. This method throws an IllegalArgumentException if the make is "Jeep". An overloaded constructor which takes the gas tank capacity. This method throws an IllegalArgumentException if the capacity of the gas tank is not between 15 and 20 gallons (inclusive). . That's 3 constructors in total. Each constructor, once done executing, should have fully initialized all of the object's properties .a default constructor Do not implement a toString method; assume one is properly defined for you. . Do not implement any getters or setters. In java
