A mountain climbing club maintains a record of the climbs that its members have made. Information about a climb includes the name of the mountain peak and the amount of time it took to reach the top. The information is contained in the ClimbInfo class as declared below. The ClimbingClub class maintains a list of the climbs made by members of the club. The declaration of the ClimbingClub class is shown below. You will write implementations of the addClimb method. import java.util.List; import java.util.ArrayList; class ClimbInfo { private String name; private int time; /** Creates a ClimbInfo object with name peakName and time climbTime. * * @param peakName the name of the mountain peak * @param climbTime the number of minutes taken to complete the climb */ public ClimbInfo(String peakName, int climbTime) { name = peakName; time = climbTime; } /** @return the name of the mountain peak */ public String getName() { return name; } /** @return the number of minutes…
In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…
Create a C++ class named Rectangle, which has two data members one is the breath and the other is the length of the rectangle. Write set() and get() methods to store and return breath and length of the Rectangle class. It also has a function named Area() which calculated the area of the rectangle. Input the length and the breath of the rectangle from the user and calculate the area of the rectangle.
C++ program Write a method that displays information about a movie. The method accepts the movie title, running time in minutes and the release year as arguments. Provide a default value for the running time so that if you call the method without minutes, it defaults to 90. Write a main() method that demonstrates you can call the method with two or three arguments. Save the file as Movie.cpp
use only C# programming Write a method call CubeIt(int x, ref int cube) that takes two arguments and does not return a value. The method will cube the first argument and assign it to the second argument.In your main, call this method twice and print the value of the parameters after each method call. Write a method with the following header: static void CalculateTuitionFee(int numberOfCourses, double costPerCourse, ref double fees). This method will calculate and assign the required fees amount to the third argument. [Fees = number of courses * cost per course + 15.25].From your program Main() method, call the CalculateTuitionFee () method four times supplying different arguments each time and display the value of the third argument after each method call. Write a method that takes four parameter of type int. The method will assign the sum of the first two arguments to the third and the difference of the first two to the fourth. This method should be coded so that the calling…
Program62.javaWrite a program that prompts for a full name (first and last) and assigns it to one string. The program then passes the full name to a void method as its sole parameter. The void method should print the first name, on one line, as many times as indicated by the length of the last name. Sample Output (image below) Program64.javaWrite a program that demonstrates method overloading by defining and calling methods that return the area of a triangle, a rectangle, or a square.
PART B: JUnit Testing Write a Java program according to the following: Create a Multiple.java class. Create the following two static methods (with return type float): SquareRoot() and CubeRoot(). SquareRoot) method should take two arguments and return the float value at the end. CubeRoot() method should take three arguments and return the float value at the end. Create a test class with the name MultipleTest.java. In this class, import the following libraries at the top of this file import org.junit. Before; import org.junit. Test; import static org.junit.Assert.assertEquals; Create an object of Calculator.java class by writing the following code in CalculatorTest.java class: private Multiple multiple; @Before public void setup() {this.multiple new Multiple():) 4. Generate the JUnit test classes for both the methods one by one. Declare and initialize the required variables to pass those to the methods. Store the expected result in one of the variables and then compare it with the…
INSTRUCTIONS: Write a C++ script/code to do the given problem. Write a class called profileID, which has data members firstName,lastName, age, birthday and ageCompany (the age when you entered in the company). Remember to use set and get methods to access the data members this time. Also, write another class called bonusAward that has a method getBonus()with arguments yos and etype which are both integer data types. This method calculates the bonus received by an employee using this formula: yos*1000 + etype*1000. Write two derived classes, ASE and SE, using multiple inheritance usingprofileID and bonusAward as parent classes. Both classes must have amethod named getyos()that returns the yos of an employee using the formula age–ageCompany; and a method named getetype() which returns a constant based on the employee type. For ASE, the constant is 10 while for SE that constant is 20. Last, write a main program where you instantiate ASE as employee1 and SE as employee2. Get their…
A point in the x-y plane is represented by its x-coordinate and y-coordinate. Design a class,pointType, that can store and process a point in the x-y plane. You should then perform operations on the point, such as setting the coordinates of the point, printing the coordinates of the point, returning the xcoordinate, and returning the y-coordinate. Also, write a program to test various operations on the point. NOTE: USE C++ language solve as soon as possible
Static variables can... ...can be accessed even without creating an object of that class. ...only be accessed by static methods. ...not be accessed using class prefix. ...not be inherited.
