very urgent plz!show code - screenshots of the code and output plz Question:You are asked to develop a system to solve a real-world problem. Make sure your system usesInheritance relationship. You can choose one of the following, or you can choose any otherproblem. Make sure to use abstraction and overriding.Examples:SystemТурesFunctionsCalculate interest: this method calculates different interestLoanPersonal loanMortgage loan rate (percentage) for each type of loans.Monthly payment: this method calculates how much thecustomer will pay monthly(Loan amount + interest) /(period in years 12) ).Please note the following:1. Implement your solution using java programming language.2. Integrate objects in a driver class, where the user will choose the type and objects willbe instantiated accordingly.3. Make sure to present your system effectively and in a well-organized manner.

Answer the given question with a proper explanation and step-by-step solution. Using Java Create an BankAccount Class that has an account id number (of type integer), balance (of type double), and rate (of type double) as private data. Add get and set methods for these three variables to work with these attributes. Make overloaded constructors to bring in and set all values, and also to just to bring in a customer name and id which uses 0 for the balance. Include error handling in the set for the balance which throws an exception if a change would put the balance below 0. In Main of another class file create 2-3 objects of BankAccount and work with their values and output them to the user to test your new class. Take the BankAccount Class from above and copy it into this program. You will use it as one of the classes in this one. Create a BankCustomer class with 3 BankAccount objects inside it as private variables (of type BankAccount) as well as a customer name (of type String).…
Do the following in Java and provided source code with screenshots of correct output to show it works! (New Solution without AI) 1. Create an interface Vehicle that contains three void, abstract methods named Start, Stop and Change Speed. 2 .Create an Airplane class (not abstract) that uses the Vehicle interface in Q1. The code for all methods should print simple messages to the screen using System.out.println(). Add an integer speed variable that is changed using the Change Speed method. ChangeSpeed adds 5 to the speed each time it is called. Create a default constructor that sets the initial speed to 0. Don't create other constructors or any setter/getter methods. 3. Create an abstract class Car that also uses the Vehicle interface in Q1 and has three variables, Year, Make, and Speed. Include the following: One constructor that accepts the car's year and make as arguments. The constructor should also assign 0 to the speed variable. Do not create other constructors. Create a void…
Follow the usual approach: read the documentation carefully, read the first test class, write the method being tested.: JAVA public EmployeeUtilities() \\constructor\\ Constructor does nothing, i.e. public EmployeeUtilities() {} ------------------ getEmployeeWithMostHours public Employee getEmployeeWithMostHours(Employee[] emps) Returns the Employee object with the most hours worked in a week over all the Employees in an input array. You can assume the array is full, i.e. there are no null elements. Parameters: emps - An array of Employee objects Returns: The Employee object with the most hours worked in a week over all the Employees in an input array. ------------------------ getHoursArray public double[] getHoursArray(Employee[] emps) Returns an array of just the total hours for each Employee in the input array. For example, if the input array has three employees with total hours: 40, 50, 20, then a double array will be returned with these values: [40,50,20] Parameters: emps - An…

Help, I am making a elevator simulation using polymorphism. I am not sure to do now. Can you help me improve this code. Please if possible don't change what I have too much. Any help would be appreciated. My code is at the bottom, that's all I could think off. 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. public abstract class Passenger {…

Java program requirements:- a PesoCurrency class with an amount attribute.- Define an overloaded convertTo method that will convert amount attribute to dollars and euros.- Conversion: 1 dollar = 50 pesos while 10 dollars = 2 euros.- Implement the class to ask the user an amount in peso to convert and will display the dollar and euro equivalent of the inputted peso amount.
In python how do you: Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's 10.0 34.0 2.0 1.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is: Nutritional information per serving of None:…
What is not the use of “this” keyword in Java? a) Referring to the instance variable when a local variable has the same name b) Passing itself to the method of the same class c) Passing itself to another method d) Calling another constructor in constructor chaining
IN C++ Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in the constructor, and the initial fuel level is 0. Provide another parameterized constructor which takes both efficiency and fuel as parameters. Also supply methods getGasInTank, returning the current amount of gasoline in the fuel tank. getEfficiency() return the efficiency of car. setGasInTank(double fuel), to add gasoline to the fuel tank. setEfficiency(double efficiency) Supply a method Drive () that simulates driving the car for a certain distance, reducing the amount of gasoline in the fuel tank according to its efficiency. Sample usage: Car myHybrid (50); // 50 miles per gallon myHybrid.addGas(20); // Tank 20 gallons myHybrid.Drive(100); // Drive 100 miles double gasLeft = myHybrid.getGasInTank(); // Get gas remaining in tank Supply a main method that tests…
In OOP, what can you say about a method that requires a lot of parameters? 1. Probably the method is in the wrong class as the method is using a lot of inputs from the outside 2. Sign of high modularity 3. Having methods with long parameter list is the norm in OOP 4. The method is doing a critical task, which explains why it needs all these parameters
Using the Java language, write a definition for the PERSON class to represent a person's name and another variable to represent his age, and a constructor method that receives data values upon creation. The definition also includes change methods and retrieval methods for each variable of the class. In addition, the class definition contains a RESET method to change the value of both variables with new values that are received from during transactions
