Program Plan Intro

Display angles

Program Plan:

• Import the required packages.
• Declare the necessary variables
• Create new circle.
• Create new line
• Create new text
• Create a class “Myclass”:
  • Using start initialize the required.
    • Create a new pane
    • Add the created elements into the pane.
    • Create a scene based on the defined positions.
    • Set title for the preview.
    • Display the results based on the mouse action made.
    • Calculate the position of x and y coordinates along with the height and width.
    • Assign the action that has to be performed when the move action is performed for the circle 1, circle 2, circle 3.
  • Define a method “setLines()”
    • Set the positions of x and y for the line 1, line 2, line 3.
    • Declare the necessary angles to get the position.
    • Compute the angles.
    • Loop that iterates to display the computed values.
  • Define the main method.
    • Initialize the call
