Write code to declare and instantiate an object of the Random class (call the object reference variable rand). Then write a list of expressions using the nextInt method that generates random numbers in the following specified ranges, including the end points. Use the version of the nextInt method that accepts a single integer parameter. a. 0 to 10 b. 0 to 500 c. 1 to 10 d. 1 to 500 e. 25 to 50 f. -10 to 15

3. Create a program for Smalltown Regional Airport Flights that accepts either an integer flight number or string airport code from the options in Figure 8-33. Pass the user’s entry to one of two overloaded GetFlightInfo() methods, and then display a returned string with all the flight details. The method version that accepts an integer looks up the airport code, name, and time of flight; the version that accepts a string description looks up the flight number, airport name, and time. The methods return an appropriate message if the flight is not found. Farrell, Joyce. Microsoft Visual C#: An Introduction to Object-Oriented Programming (MindTap Course List) (p. 347).

Write a class method named countOccurences that returns the number of times a particular integer occurs in an array of integers. The integer and the array will both be parameters.

Help, I making a elevator simulator, I need help in writing code in the Elevator class and it's polymorphism class. I am not sure what to do next. Any help is appreciated. There are 4 types of passengers in the system:Standard: This is the most common type of passenger and has a request percentage of 70%. Standard passengers have no special requirements.VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priority and are more likely to be picked up by express elevators.Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators.Glass: This type of passenger has a request percentage of 5%. Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators. There are 4 types of elevators in the system:StandardElevator: This is the most common type of elevator and has a request...

can someone help me? The questions are: 1. Add an addExerciseAdd method that adds an exercise to a private variable exercises in Exercise You don't need to create a getter or setter for this private variable. 2. Modify the constructors in Exercise so that you can create two types of workouts (let one constructor use the other; each variable can only have a value in one constructor): a training schedule with exercises, but without a trainer. a training schedule with exercises and with a trainer. import java.util.ArrayList;class Exerciseplan {private String customer;private String trainer;Exerciseplan(String customer) {this.customer = customer;}Exerciseplan(String customer, String trainer) {this.customer = customer;this.trainer = trainer;}private void printExercise(String name, String muscleGroup, Integer numberOfSets, Integer repetition, Integer restTime) {System.out.println("Oefening voor " + muscleGroup + ":" +" herhaal " + numberOfSets + " keer " +"(rust tussendoor " + restTime +...

You will build a program to manage a race car in this assessment. The code will consist of a for-loop method that will run a car around a race track and cause "wear and tear" on the car. The car will perform x number of laps and will have to make pitstops when it either runs out of gas or needs a tire replacement. The for loop will be simple def wear_tires(car): tire -=1 def use_gas(car): gas -=1 c = Car() # You need to make this part for i in range(100): if the car needs a pitstop: perform pitstop else: wear_tires(c) use_gas(c) # Display the current cars wear in a much better format print(c.tire) print(c.gas) print("Current Lap is: " , i) For this task, you will have to use this for loop and build out the two methods in the main Python program. To use the above code, you must build two pieces of information. An abstract Vehicle class A Car class A RaceCar class Each with its methods and variables. This programming will involve using inheritance and abstraction to make a race car...

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...

Exercise 5 - Number to Word Make a new class in the Lab2 project called Num2wordthat prompts the user enter a number between 0 and 9 and then displays the corresponding word (i.e. "zero"for 0, "one"for 1, etc.). Use a switchstatement to do this. Include a default case that lets the user know they entered a wrong number. The switch statement has the following syntax: switch (variable) { case value1: // Code that should execute when variable==value1 break; // this prevents it from automatically going to the next case case value2: // Code that should execute when variable==value2 break; // this prevents it from automatically going to the next case default: // Code that should execute when variable has a value that didn't match the above }
