Create a new Java project named Program 4 Three Dimensional Shapes. In this project, create a package named threeDimensional and put all 3 of the classes discussed below in this package
Javadoc requires that every class, every field, every constructor, and every method have a general (useful) comment and all relevant tags. This includes @param tags for methods and constructors and @param and @return tags for methods.
- Create a Cube class with the following:
- 1 data member: an integer named lengthOfSide
- 2 constructors: a no-argument constructor that set lengthOfSide to 1 and one that takes lengthOfSide as an argument
- A getter and a setter for lengthOfSide
- A toString() method for Cube that simply returns the string "Cube: [lengthOfSide]"
- A getSurfaceArea() method that returns the surface area of this cube.
- A getVolume() method that returns the volume of this cube.
- Make sure to Javadoc EVERYTHING!
- Create a Sphere class that has everything that the cube class has except:
- Instead of lengthOfSide, Sphere has radius.
- Note that if you choose to copy and paste, nearly everything will change because of radius
- Make sure to Javadoc EVERYTHING! This means that if you copy and paste from Cube, there should be no mention of Cube or lengthOfSide in the javadoc.
- Create a third class named Program4 which has a main method. It should make use of Cube and Sphere to do the following:
- Create a Scanner named scanner off of standard input.
- Create a Cube named firstCube and use the default (no-argument) constructor to populate the reference
- Print out firstCube
- Prompt the user with "Please enter the length of the side for secondCube: "
- Read in the next integer and use it to set the length of the side of secondCube. DO NOT USE A CONSTRUCTOR TO SET THE LENGTH OF THE SIDE.
- Make new Cube named thirdCube with sides equal to 3. USE THE ARGUMENT CONSTRUCTOR TO DO THIS.
- Make a new integer named accessorValue and have it store the getter value for firstCube.
- Output "First Cube side length: ", "Second Cube surface area: ", and "Third Cube volume: " along with their values (use accessorValue for First Cube)
- Output all three Cubes in order along with the labels "First Cube: ", "Second Cube: ", and "Third Cube: " in the appropriate places. Then print out a new line
- Repeat steps 1-9 above for Spheres. All variable names, all prompts, and all outputs should make sense.
- Remember to Javadoc Program4 and the main method!

- In java language Class Design – Date V0.0 & V1.0 Create a new project for this lab and create a new class inside called Date. If you created a Date class last week, you may use it as a base. What does it mean to be a Date? What data items (called “state”) do you need to keep track of? Alternatively, what does a date have? (“has a” == composition) What can a Date do? What are the actions and verbs that can be applied to a date? Come up with one or two. These become the class’s methods. Try adding 3 data items to your Date to manage the month, day and year. Should these be local variables? Class-level (or instance) variables? Now let’s build a method to set the date This function should take 3 integers as input and assign these to your instance variables declared in the previous step. public void setDate(int m, int d, int y) { And, let’s build a method to report the date This function takes no input and uses the console to output the Date in the format…arrow_forwardCreate 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…arrow_forwardCreate a UML diagram to document the Cuboid class. You can model this class after the Rectangle class we covered in this chapter. It should have 3 data fields: width, length, height. It should have 3 accessors and 3 mutators. It should have a method that calculates the volume of the cuboid. Save your file in MS Word or PDF format. Hint: In MS Word, you can create a table of 1 column and 3 rows. What is a cuboid? You can consider a cuboid as a cube whose length, width, and height may not be equal to each other.arrow_forward
- Complete the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information. Ex: If the input is: 2011 18000 2018 where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs: Car's information: Model year: 2011 Purchase price: $18000 Current value: $5770 Note: print_info() should use two spaces for indentation.arrow_forwardDevelop the code that would be used in the main() function to test the class Cube.

- Create a TeeShirt class for Lebo’s Tee Shirt Company. Attributes include an order number, size, color, and price. Create set methods for the order number, size, and color and get methods for all four attributes. The price is determined by the size: R122.99 for XXL or XXXL, and R109.99 for all other sizes. Create a subclass named CustomTee that descends from TeeShirt and includes an attribute to hold the slogan requested for the shirt, and include get and set methods this field. The display() method should me an abstract method. Write a test class named DemoTees.java that creates two objects of each class, and demonstrate that all the methods work correctly by communicating to the user to input the tee shirt size, color, and slogan, then display the tee shirt order number, size, color, slogan and price. Format your output to 2 decimal places.

A string data field named name for the stock’s name. A double data field named previousClosingPrice that stores the stock price for the previous day. A double data field named currentPrice that stores the stock price for the current time. A constructor that creates a stock with the specified symbol and name. A method named getChangePercent() that returns the percentage changed from previousClosingPrice to currentPrice. Write a test program that creates a Stock object with the stock symbol ORCL, the name Oracle Corporation, and the previous closing price of 34.5. Set a new current price to 34.35.

- Expert this is warming, don't use any AI platform and don't give plagiarised response to me. If I see plagiarism and AI detection I'll report your account and reduce rating.You have a basic User class for a social media platform. Your task is to enhance the class by introducing a new method called 'post_status.' This method should take a single parameter, which is the status message that the user wants to post. The objective is to implement this method to update the user's status.Next, instantiate a new object of the User class, naming it 'SocialUser.' Utilize the extended class with the newly added 'post_status' method. Your next step is to post three distinct status messages for 'SocialUser'—namely, 'Excited for the weekend!', 'Just finished a great book!', and 'Exploring new hobbies!'To conclude, utilize the 'display_info' method to showcase the updated information about 'SocialUser.' Verify that the output includes details about the newly added status messages, ensuring that they…arrow_forwardNumber 20arrow_forwardModalProp detailsanimationType it's an enum of ('none', 'slide', 'fade') and it controls modal animation.visible its a bool that controls modal visiblity.onShow it allows passing a function that will be called once the modal has been shown.transparent bool to set transparency.onRequestClose (android) it always defining a method that will be called when user tabs back buttononOrientationChange (IOS) it always defining a method that will be called when orientation changessupportedOrientations (IOS) enum('portrait', 'portrait-upside-down', 'landscape', 'landscape-left', 'landscape-right')Modal component is a simple way to present content above an enclosing view.using given Modal make a Basic Example?arrow_forward
