Program Plan Intro

Program to draw concentric rings

Program plan:

  • Import the required graphics package.
  • Define the main method.
    • Using the object GraphWin() to display the graphics window.
    • Using the method setCoords(), set the size of the graphics window.
    • Using the method Circle(), draw the circle.
    • Using the method setOutline(), set the outline of the object to the given color.
    • Using the method setFill(), set the interior of the object to the given color.
    • Using the method setWidth(), set the width of the outline of the object to the desired number of pixels.
    • Using the method draw(), draw the square inside the graphics window.
    • Use the same methodology for drawing other colors in the graphics window.
  • Call the function “main()”.

Java Graphics (Bonus In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. " The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels. Regardless of how…
