Convert the following UML diagram into the Java code. Write constructor, mutator and accessor methods for the given class. Create an instance of Account class in a main method using a Demo class. Note: The structure of the class can be compiled and tested withou having bodies for the methods. Just be sure to put in dummy return values for methods that have a return type other than void.

Directions: SHOW ALL YOUR WORK. REMEMBER THAT PROGRAM SEGMENTS ARE TO BE WRITTEN IN JAVA. Notes: Assume that the classes listed in the Quick Reference found in the Appendix have been imported where appropriate. Unless otherwise noted in the question, assume that parameters in method calls are not null and that methods are called only when their preconditions are satisfied. In writing solutions for each question, you may use any of the accessible methods that are listed in classes defined in that question. Writing significant amounts of code that can be replaced by a call to one of these methods may not receive full credit. An APLine is a line defined by the equation ax + by + c = 0 , where a is not equal to zero, b is not equal to zero, and a, b, and c are all integers. The slope of an APLine is defined to be the double value -a b/ . A point (represented by integers x and y) is on an APLine if the equation of the APLine is satisfied when those x and y values are substituted…
This is for python class, so please answer in python 9.12 LAB: Product class In main.py define the Product class that will manage product inventory. Product class has three attributes: a product code, the product's price, and the number count of product in inventory. Implement the following methods: A constructor with 3 parameters that sets all 3 attributes to the value in the 3 parameters set_code(self, code) - set the product code (i.e. SKU234) to parameter code get_code(self) - return the product code set_price(self, price) - set the price to parameter price get_price(self) - return the price set_count(self, count) - set the number of items in inventory to parameter count get_count(self) - return the count add_inventory(self, amt) - increase inventory by parameter amt sell_inventory(self, amt) - decrease inventory by parameter amt
ques هذا السؤال بشكل PDF in java The class underGraduate contains: • Four data field named name, id, studYears, and average. • A constructor that creates a underGraduate with the specified id and average. • A constructor that creates a underGraduate with the specified studYears. • Methods display() to print id, name and average. Design the underGraduate class. Also write a program in java to read information of n students in the CIS dept. and write 1. Method to print all the information of student who late for their peers. 2. Method to check if there are id frequent or not by print the student name. ضافة ملف صفحة 4 من 4 ارسا|
Finish the TestPlane class that contains a main method that instantiates at least two Planes. Add instructions to instantiate your favorite plane and invoke each of the methods with a variety of parameter values to test each option within each method. To be able to test the functionality of each phase, you will add instructions to the main method in each phase.
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 +…
Program - Python Make a class.The most important thing is to write a simple class, create TWO different instances, and then be able to do something. For example, create a pizza instance for Suzie, ask her for the toppings from the choices, and store her pizza order. Then create a second pizza instance for Larry, ask for his toppings and store his pizza order. Then print both of their orders back out. You do not need to make your class very complicated. (Shouldn't be the pizza example but something similar)

Instructor note: This lab is part of the assignment for this chapter. This lab uses two Java files, LabProgram.java and SimpleCar.java. The SimpleCar class has been developed and provided to you already. You don't need to change anything in that class. Your job is to use the SimpleCar class to complete the specified tasks in the main() method of LabProgram.java Given two integers that represent the miles to drive forward and the miles to drive in reverse as user inputs, create a SimpleCar object that performs the following operations: Drives input number of miles forward Drives input number of miles in reverse Honks the horn Reports car status The SimpleCar class is found in the file SimpleCar.java. Ex: If the input is: 100 4 the output is: beep beep Car has driven: 96 miles
Consider the class definition shown below. Notice that some lines have been replaced by descriptions (in angle brackets) of the code required. The class defines a constructor and a method named run. Fill in the appropriate Java and then answer the questions: A) How many variables in total are referenced by the program? B) How many data types are used? Applying a run method of this class will print...
Match the following: Public A. constructor methods В. A class that contains no methods (other than constructors) that change any of the data in its object method signatures C. modifier means that there are no restrictions on where an instance variable or method can be used Immutable class D. hiding implementation details is done by marking data and methods as Call-by-reference Е. When we call a method in Java using class type parameters method name F. v Overloading is achieved when two or more methods in the same class have the same Accessor methods G. H. private
Use the class diagram below to create a Parking Charge class for an object-oriented parking system. Write your code using java. Classes should contain properties and method implementations. N.B. Try to make your code readable.
Overriding is useful when a method has the same signature and type as a method in the parent class. O a local variable has the same name as an instance variable. O you want to change the return type of a method. O a method has the same signature as another method in the same class.
