Step by step
Solved in 2 steps
- When you redefine the __str__ method in a class, the keyword print has different meanings based on what objects are passed through it. What is this an example of? (In python)Create an application named SalesTransactiobDemo that declares several SalesTransaction objects and displays their values and their sum. Name - The salesperson name (as a string) sales Amount- The sales amount (as a double) commission- The commission (as a double) RATE- A readonly field that stores the commission rate (as a double). Define a getRate() avcessor method that returns the RATE Include 3 constructors for the class. One constructor accepts values for the name, sales amount, and rate, and when the sales value is set, the constructor computes the commission as sales value times commission rate. The second constructor accepts a name and sales amount, but sets the commission rate to 0 The third constructor accepts a name and sets all the other fields to 0The LocalDate class includes an instance method named lengthOfMonth() that returns the number of days in the month. Write an application that uses methods in the LocalDate class to calculate how many days are left until the first day of next month. Display the result, including the name of the next month. Save the file as DaysTilNextMonth.java.
- ~Java Program ~ Write a small application with a GUI that could be the basis of a larger application. Your application will allow someone to enter a user nameand password to separate text fields. When the user clicks the Login button, you should check whether the string in the name field matches "John" and the string in the password field matches "myPassword". If both match, put the message You have been logged in on a result label. If they don't match, put the message Sorry, that password is not valid on the result label.Create a program that uses classes, polymorphism, and enums to monitor blizzards in Europe, with class members including the blizzard name, location, and snowfall amount, with a continuous menu to update, delete, display, search and add data stored in a collection. The application should have a menu that allow users to: • Add a new item to the collection. • Display all the items in the collection. • Search for a specific item. • Exit the application by pressing 0. The application should also display any error messages if the user enters invalid input. Coding Requirements: 1. Demonstrate applied use of foreground color and change in console title 2. Classes created and apply generics, abstract, and polymorphismTrue of False. When comparing two objects using the equals method inherited from the Object class, what is actually compared is the contents of the objects. Group of answer choices True False
- Use Python: code: class MyClass: # Constructor def __init__(self, var1, var2): self.var1 = var1 self.var2 = var2# Method that returns the value of var1 def get_var1(self): return self.var1# Method that returns the value of var2 def get_var2(self): return self.var2 # Method that sets the value of var1 def set_var1(self, var1): self.var1 = var1# Method that sets the value of var2 def set_var2(self, var2): self.var2 = var2# _str_ method that returns values of var1 and var2 def __str__(self): return "var1: {}, var2: {}".format(self.var1, self.var2)# Creating an object of MyClassobj = MyClass(int(input("Enter var1: ")), int(input("Enter var2: "))) # Setting var1 of obj to var1 ** 2obj.set_var1(obj.get_var1() ** 2)# Setting var2 of obj to var2 ** 2obj.set_var2(obj.get_var2() ** 2)# Printing var1 and var2 of the objectprint(obj) In the above class (MyClass), overload __add__, __eq__, and __lt__ operators as follow:a)…__eq__(self, other): Method that returns True if self and other are considered the same Flight: if the origin and destination are the same for both Flights. Make sure that if “other” variable is not a Flight object, this means False should be returned. getFlightNumber(self): Getter that returns the Flight number getStart(self): Getter that returns the Plane Start getgoingTo(self): Getter that returns the Plane destination isDomesticFlight(self): Method that returns True if the flight is domestic, EX within a country (the Start and goingTo are in the same country); returns False if the flight is international (the Start and goingTo are in different countries) setStart(self, origin): Setter that sets (updates) the Plane Start setgoingTo(self, destination): Setter that sets (updates) the Plane GoingToTask 01: Create the Insurance class. Task 02: The calculatePremium() calculates and returns the premium. Task 03: The Insurance program accepts a current year and date of birth from the user and displays the premium.

The below form will represent the main form from which the user will navigate to the other forms. Meaning each button should be linked to the appropriate form. E.g. If button Manage Addresses is clicked the form managed addresses should be displayed. The Exit button should successfully terminate the program. Create a void method for each button and name them as follow: LinkToAddresses (), LinkToCustomers (), LinkToDrivers (), LinkToStatus (), and LinkToFreight (). The methods should be called under the appropriate button. For the exit button create a void method named AppExit () this should terminate the program.
