Question
Study the 2 files provided with this question RectangleClassUMLandCode.pdf and RectangleDemo.java . Notice that the file RectangleClassUML&Code.pdf contains both the UML design & code for the class Rectangle. The code for class Rectangle serves as a "blueprint" for creating Rectangle objects. The second file, "RectangleDemo" is an application program (contains a method main) that uses the Rectangle class to create Rectangle objects.
Now complete the followign activity:
Part 1: Create a new Java project, name it Chap6-Pet and click Finish and OK. Next, create a new class, name it Pet, and DO NOT check the first check box under "Which method stubs would you like to create?" and click Finish. Study the file PetClassUML.pdf. Code the file "Pet.java" according to this design. Save the file.
Part 2: Next, for the same project, create another class, name it PetDemo, and check the first checkbox under "Which method stubs would you like to create?" and click Finish. This file will serve as a application program. Add code to this file to create 2 Pet objects named pet1 and pet2. Then set their data by calling the appropriate "set" methods from the Pet class, and print their data by calling the appropriate "get" methods from the Pet class:
Sample Output
Pet 1 => Felix 1 cat
Pet 2 => Buddy 2 dog
(THE ATTACHED IMAGES ARE IMAGES OF THE PDF's STATED ABOVE) and the link below is the other pdf (USE THE RECTANGLE CODE IMAGE AND PDF to structure your code using the PET PDF)

Explain the relevant improvements as well. (Examples might have different object, labels and organization)arrow_forwardFor 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 }arrow_forwardBelow for each class you find a UML and description of the public interface.

There are multiple ways of implementing all these classes. Feel free to add private properties and methods. For each object, it's mandatory to create a header file (.h), implementation file (.cpp) and a driver. Blank files are included. The header should have the class definition in it. The implementation file should contain the implementations of the methods laid out in the header fine. And finally the Driver should test/demonstrate all the features of the class. It's best to develop the driver as the class is being written. Check each section to see if there are added additional requirements for the driver.

- Write a graphical application that contains a class named RV whose objects are the recreational vehicle designed and digitized as described in Knowledge Exercises 20 and 21 (you can design your version as well. Simple car shape is will be appreciated. The class’s private data members should be the vehicle’s body color and (x, y) location. a) Give the UML diagram for the class. It should include a three-parameter constructor, a toString method, a method to input the values of all of an object’s data members, and a show method to draw the RV at its current (x, y) location. b) Progressively implement and test the RV class by adding a method and verifying it before adding the next method. A good order to add the methods to the class is the three-parameter constructor, followed by the toString method, the show method, and finally the inputmethod.
