Draw the UML diagram for the class. Implement the class. Write a test program that creates an Account object with an account ID of 1122, a balance of 20,000,ドル and an annual interest rate of 4.5%. Use the withdraw method to withdraw 2,500,ドル use the deposit method to deposit 3,000,ドル and print the balance, the monthly interest, and the date when this account was created.

Write and document the definition for the Product class. The Product class represents an item that would appear for sale on a Web site or in a department store (like a toaster). Each Product object has three instance variables: description, productNumber and price. The class has one constructor that takes three parameters in the order productNumber, description and price. The class has one accessor method named getCost(int qty) which returns the price for qty items of the Product. The class has two mutator methods—setPrice() and setDescription()—that modify the corresponding instance variables. The class has a toString() method that returns the Product as a String in the form: 34567: Small Toaster, $ 17.95. Note: use concatenation to construct the returned string. Do not use the String.format() method to format the returned value.

Write a program which controls a metro train and that keeps track of stations and who gets on and off. write a short description of how the code is designed. Design and implement a class called train, which has at least the following: At least the following attributes (you can include others): metroID stationNum which keeps track of the station that the train is at. iii. direction which keeps track of the direction the train is travelling in. passTotal which keeps track of the number of passengers currently on the train. A default constructor which sets the metroID to a random number between 1 and 1000, the station number to 0, the direction (int), and the passTotal to 0 (train is empty). A constructor with one parameter; the parameter is the metro id. The constructor assigns the passed integer to the metroID attribute; the rest of the attributes are set as described in the default constructor. Accessor methods for each attributes. Mutator methods for each attributes....

Write a Rectangle class. Its constructor should accept length and width as a parameter. It should have methods that return its length, width, perimeter, and area. (Use Java) Show a demonstration where you create two separate rectangles.

Create a Point class to hold x and y values for a point. Create methods show(), add() and subtract() to display the Point x and y values, and add and subtract point coordinates. Create another class Shape, which will form the basis of a set of shapes. The Shape class will contain default functions to calculate area and circumference of the shape, and provide the coordinates (Points) of a rectangle that encloses the shape (a bounding box). These will be overloaded by the derived classes; therefore, the default methods for Shape will only print a simple message to standard output. Create a display() function for Shape, which will display the name of the class and all stored information about the class (including area, circumference and bounding box). Build the hierarchy by creating the Shape classes Circle, Rectangle and Triangle. Search the Internet for the rules governing these shapes, if necessary. For these three Shape classes, create default constructors, as well as constructors...

Create a Class Student in which we have three instance variables emp_name, emp_id, and Salary. Write getter and setters for each instance variable. Write another Display method that displays the record of Employee. In Main create five Employee’s Objects. Set their values as required and display as well. In the end Display top three employees with respect to Salary (Display those who have more Salary among all).

For this lab task, you will work with classes and objects. Create a class named text that works similar to the built-in string class. You will need to define a constructor that can be used to initialize objects of this new class with some literal text. Next, define three methods: to_upper() that will convert all characters to uppercase, reverse() that will reverse the text and length() that will return the length of the text. After you have completed this part, copy the following mainfunction to your code and check if the implementation is correct. int main() { text sample = "This is a sample text"; cout << sample.to_upper(); // This should display "THIS IS A SAMPLE TEXT" cout << endl;cout << sample.reverse(); // This should display "txet elpmas a si sihT"cout << endl; cout << sample.length(); // This should display 21 }

Write a tester program to test the mobile class defined below. Create the class named with your id (use : Id 190099306) with the main method. Create two mobiles M1 and M2 using the first constructor. Print the characteristics of M1 and M2. Create one mobile M3 using the second constructor. Change the id and brand of the mobile M3. Print the id of M3. Your answer should include a screenshot of the output. public class Mobile { private int id; private String brand; public Mobile() { id = 0; brand = ""; } public Mobile(int n, String name) { id = n; brand = name; } public void setBrand(String w) { brand = w; } public void setId(int w) { id = w; } Public int getId() { return id; } public String getBrand() { return brand; } } please provide me how to do the steps and i will try to work it alone. we didn't study this excersie in the lab

in JAVA Assume that a receipt id contains characters that represent information or that can be used as a code to determine something about the purchase. For example: if an id has an 'x' followed by two 'y's, it means that the purchase was a final sale and cannot be returned. Or if an id has an 'a' followed by three 'b's, it means that a coupon was used for purchase. Write a static method for the Receipt class to test whether a receipt id meets such a criteria. Does the id meet the criteria? The criteria is described by three pieces of data, passed in as parameters: char firstTarget char second Target int countOfSecond After First A receipt id meets the criteria if: the id contains the first target character and the second target character appears exactly the specified number of times after the first target character appears Note: the first and second char could be the same char! Carefully review the provided driver program for examples of ids that meet and don't meet criteria. For full...

Can you help me with this please: Write the definition of a class swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also, add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time, if the water in the pool exceeds the total capacity of the pool, output "Pool overflow" to indicate that the water has breached capacity. The header file for the swimmingPool class has been provided for reference. Write a program to test your swimmingPool class. An example of...

Design a class called "Person" with attributes for name, age, and gender. Implement methods to get and set these attributes, and also a method to calculate the person's age in dog years (assuming 1 dog year is equivalent to 7 human years).
