Add a String instance variable, messageUponExiting, to the Window class. This variable will be used to display a message when the user closes the window (for example, "Are you sure you want to quit?"). Furthermore, this variable should be accessible to all subclasses of the Window class, as each sort of window may require a different message upon exiting. Please provide the declaration of the instance variable only—nothing else.

Create a Class Pet with the following data members Identification: String species : String (e.g. cat, dog, fish etc)  breed: String  Age (in days): int  Weight: float  Dead: boolean 1. Provide a constructor with parameters for all instance variables. 2. Provide getters for all and setters for only breed, and weight 3. Provide a method growOld() that increases the age of the pet by one day. A dead pet wont grow old 4. Provide a method growHealthy(float w) that increases the weight of the pet by the given amount w. A dead pet cannot grow healthy. 5. Provide a method fallSick(float w) that reduces the weight of the pet by the given amount. The least weight a pet can have is 0 which will mean that the pet has died. If the value of weigh is 10 kg and the method is called with an argument of 11 kg then you will set it to 0 and set the dead to an appropriate value to mark the death of the pet 6. Provide a toString method that shows an appropriate well formatted string...

The next sections will provide you with the definitions of the classes MonthCalender and DateTimerPicker respectively.

The first version of Abby’s Eggs worked but was a bit cumbersome. I.e. you couldn’t edit a single parameter, you had to always re-enter all of them. Store the parameters (number of chickens, eggs laid per day, etc.,) in static fields of the class. Have separate methods for updating the parameters. Use a switch statement to take menu selections for updating parameters or outputting results. If the menu choice is 0, the program should terminate, invalid inputs should be ignored and any prompt repeated. Before displaying updated menu, "clear the screen" I got most of the code working, but I can't find a way to clear the sceen before displaying the updated menu. I tried using "System.out.print("033円[H033円[2J"); System.out.flush();", but it is not working. I am using the Apache NetBeans IDE.

The goal of this coding exercise is to create two classes BookstoreBook and LibraryBook. Both classes have these attributes: author: Stringtiltle: Stringisbn : String- The BookstoreBook has an additional data member to store the price of the book, and whether the book is on sale or not. If a bookstore book is on sale, we need to add the reduction percentage (like 20% off...etc). For a LibraryBook, we add the call number (that tells you where the book is in the library) as a string. The call number is automatically generated by the following procedure:The call number is a string with the format xx.yyy.c, where xx is the floor number that is randomly assigned (our library has 99 floors), yyy are the first three letters of the author’s name (we assume that all names are at least three letters long), and c is the last character of the isbn.- In each of the classes, add the setters, the getters, at least three constructors (of your choosing) and override the toString method (see samplerun...

Create a new Teller Class Build a new Teller class("Teller.java"). This class will be a sub-class of Employee. The Teller class should have all the same properties as an Employee as well as two new properties: hoursWorked and shift. HoursWorked is the total hours that this teller worked this week, and shift is either "day" or "evening" shift. Make sure to add 2 constructors and a display() method. Do not include a main() method in the Teller class. Test out this Teller class, by building a separate Tester class called TellerTester stored in a new file called ( "TellerTester.java". This TellerTester class will only have a main() method, that will instantiate a Teller object, pass all the data to the Teller constructor, and lastly call the Teller display() method; just these 3 lines.

Your module should be named "loc.py". Include instance variables for all data about a location (name, summary, details.) The constructor should allow creating a location with whatever name, summary, and details you want, but a newly create Locale has not yet been visited. The string representation of a Locale should be its summary if it has not yet been visited, otherwise it should be a brief message including its name, such as "You are at Sandy Beach." Include other observer and mutator methods as needed.

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 }

Create the VisualCounter class, which supports both increment and decrement actions. Take the function Object() { [native code] }'s two arguments N and max, where N specifies the maximum action number and max specifies the counter's maximum absolute value. Make a plot that displays the worth of the counter each time its tally changes as a byproduct.

#Testing Please test my code and see if it meet the follwing needs: The class should implement the Comparable interface. Circle one is less than Circle two if the radius of Circle one is less than the radius of Circle two. The two Circles are equal if they have the same radius. Circle one is larger than Circle two if its radius is larger. If circle One.compareTo circle Two <> 0 The Test Class displays a menu that allows the user to: Enter a Circle (the user only needs to enter the radius). Print all Circles (print the toString for each Circle in the ArrayList). Quit To adda a circle Cases: The ArrayList is empty The new circle is less than the first circle, add it at the beginning. The circle is greater than the last circle, add it at the end The new circle belongs somewhere in the middle. import java.lang.Math;public class Circle implements Comparable<Circle> {private double radius;public Circle(double radius) {this.radius = radius;}public double findArea()...

Create a class named "Rectangle" having length and width as attribute. There should be behaviors to set the values of length and width (individually and collectively), and get their values individually. There should also behavior to display the perimeters and area of the rectangle. Create another class named as Main which have two objects of Rectangle (r1, r2) having length (3.2, 20) and width (4.5, 36) respectively. Also display the length, width, perimeter and area of both rectangles note ....This is a Java Question
