Instructor note: This lab is part of the assignment for this chapter. HINT: 1). The decision means how many times to flip the coin. 2). Use a random integer variable to indicate the head or tail in each toss. Java Define a method named coinFlip that takes a Random object and returns "Heads" or "Tails" according to a random value 1 or 0. Assume the value 1 represents "Heads" and 0 represents "Tails". Then, write a main program that reads the desired number of coin flips as an input, calls method coinFlip() repeatedly according to the number of coin flips, and outputs the results. Assume the input is a value greater than 0. Ex: If the random object is created with a seed value of 2 and the input is: 3 the output is: Heads Tails Heads Note: For testing purposes, a Random object is created in the main() method using a pseudo-random number generator with a fixed seed value. The program uses a seed value of 2 during development, but when submitted, a different seed value may be used…
Create a class with a method. The method has to decide whether a given year is a leap year or not. Note- A year is a leap year if: • It has an extra day i.e. 366 instead of 365. It occurs in every 4 year e.g. 2008, 2012 are leap years. For every 100 years a special rule applies-1900 is not a leap year but 2000 is a leap year. In those cases, we need to check whether it is divisible by 400 or not. > > ClassAssignmentEx2 ©LeapYearDecider javaclassnotes.assignments javaclassnotes.assignments ClassAssignmentEx2() LeapYearDecider() main(String):void A isLeapYear(int):boolean
The method half shown below, takes a variable of type int and returns the result of dividing the variable by 2. Write the overloaded method for half that accomplishes the same task for a variable of type double. public static int half(int val) { return val/2;}
Does a method have access to the original object or a copy of it when it receives an object as a parameter?
If the value passed into the parameter x in the following method is 28. What is the value returned by this method? public static int method2(int x) { int code = x%3; switch (code) { case 2: return 50; break; case 1: return 75; break; case 0: return 100: } }
Create a class Course, which has one field: String courseName Create the constructor, accessor, and mutator for the class. Then, in the main method of this class, create an instance of the class with the name "CST1201". Write an equivalent while statement to replace the following for statement for (int i=2; i<100; i=i+2) { System.out.println(i); }
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…

The class provided represents a item. Information about a item includes the name of the item and the count of items in inventory (inventory count). When ordering items they are ordered in descending order by the inventory count. If items have the same inventory count then they are ordered in ascending alphabetical order by their name (a-z). Here is an example set of items: 7 Camera 5 Bicycle 5 Lego 5 Robot 3 Tricycle The Item class is missing a required method. Write the missing method in the space provided below. public class Item implements Comparable { private String name; private int count; public Item (String nameIn, int count In) { name name In; count countIn; }
