using eclipse part 1 Create a different package session5a. Create a class SquareDemo. Create an instance of Square in the main() method with sideLength set to 10. along with output screenshot for this part. Part 2 Create 12 Square instances in SquareDemo class with random size (1-100) and print out: If divisible by 2, print out side length If divisible by 3, print out area If divisible by 6, print out side length and area Otherwise, print out "Side length and area are hidden" along with output screenshot for this part.

Create a new project called Family. Add a person class with name, birthDate, and sex private instance variables. Create the public getter and setter methods for each. Create an overloaded constructor that initializes all of the instance variables. Create the default constructor. Override the toString () method to show the Person's info. Create the Person in the main method, and display that person's info. Now add a new instance variable to the Person class of type Person with the identifier spouse. Spouse should be private with setter and getter methods. If you try to instantiate spouse in the contructor, you will get a stack overflow error. Each Person, creates a Person, creates a Person, and so on forever. Try that to see the error and then remove the code from the constructor. Add the following logic: in Person there should be a method to show Spouse. If spouse is null, display or return "Not Married", otherwise call the toString() method. The should also be a get married method....

Write the code for the timeTick method in ClockDisplay that displays hours, minutes, and seconds, or even implement the whole class if you wish.

Write a modified Button class that creates circular buttons. Call your class CButton and implement the exact same methods that are in the existing Button class. Your constructor should take the center of the button and its radius as normal parameters. Place your class in a module called cbutton . py. Test your class by modifying roller . py to use your buttons.

Write a main program that displays a single frame with the title "My First Frame". Set the size to 800 by 800. Make the frame visible. Create a panel by using the JPanel constructor and add it to the frame.

Add a JButton and a JLabel to the panel before adding the panel to the frame. Display the results

Add a new Java class to your project by right clicking on the src folder in the Project pane and select New > Java Class.Enter Hours as the name for this class, and IntelliJ will add it to the files in the src folder for your project. Remember tocopy and insert the standard heading for the main method as you did for Program 2.Write a program that prompts the user to enter a number of hours, and produces the equivalent number of days as a wholenumber along with the number of hours left over. Assume that a day has exactly 24 hours. The following example showsthe format to use for your output, where the input entered by the user is underlined.Enter the number of hours: 100100 hours is 4 days, plus 4 hours.Define Variables: The number of hours will be a whole number, and we would like to obtain results as whole numbers ofdays and hours, so use the int data type to declare the variables to hold the numbers of hours input, as well as the results(the number of days and number of hours left...

Currently, there are two draw rectangle methods in the DoodleController class. Since two different turtles need to draw a rectangle, create a draw rectangle method in the DoodleTurtle class that will take the width and height of the rectangle as parameters and draw a rectangle of the specified size. The size will be the number of steps by the turtle. With the new method introduced, the calls to drawRectangleWithLittleTurtle and drawRectangleWithBigTurtle can be replaced with a call to the turtle’s drawRectangle method passing in the desired size of the rectangle. Refactor the DoodleController accordingly. Note: When you are done with the refactoring the drawRectangleWithLittleTurtle and drawRectangleWithBigTurtle method in the DoodleController need to be deleted. After this refactoring, do not move on until you verify the program works as it did before.
