Program Plan Intro

Two circles and their distance

Program Plan:

Import required packages.

Declare a main class named “Test” which extends the “Application” class.

Declare a “start ()” method which overrides the “start ()” method in the “Application” class. Inside this method,

Assign width as “250” to the variable “pane_WIDTH” and height as “250” to the variable “pane_HEIGHT”.

Create a Pane.

Get four random points and store it in a variable “x1”, “y1”, “x2”, and “y2”.

Create two circles named “circle_1” and “circle_2”.

Create a line named “line1”.

Create a text object that displays the distance by calling the function “get_Distance ()”.

Add the circles and text to the pane.

Create a scene and place it on the stage.

Set the title as “Exercise14_21”.

Display the stage on the window using “primaryStage.show ()” method.

Give function definition for the static method “get_Distance ()”.

Calculate the distance using “Math.sqrt ()” function and return the value.

Declare a main method using “public static main”.

Launch the method using “launch ()” method.

4. Area of a Rectangle • Write a program that compares the area of two rectangles. You can do this several ways. one way is to add the length and width of each rectangle to get it's area and then compare the two areas together. • The program should ask for the length and width of two rectangles and then tell the user which rectangle has the greater area, or if the areas are the same. • The area of a rectangle is the rectangle's length times its width. Name the source code file yourName HW4.py. • Test and run the program. Capture the output console and save it as an image file named yourName HW4 output.jpg. • Submit the py and the image files through Canvas.
