All Implemented Interfaces:
AutoCloseable
public class CodeDraw extends Object implements AutoCloseable
CodeDraw is an easy-to-use drawing library where you use code to create pictures and animations. It is made for beginners that understand little about programming and makes it very simple to draw and animate various shapes and images to a canvas.

The source code can be found in the CodeDraw repository.
If you are unfamiliar with graphical output and/or want more details you can read the Introduction to CodeDraw.

Here is an example to get you started:

 import codedraw.*;

 public class MyProgram {
     public static void main(String[] args) {
         // Creates a new CodeDraw window with the size of 600x600 pixel
         CodeDraw cd = new CodeDraw();

         // Sets the drawing color to red
         cd.setColor(Palette.RED);
         // Draws the outline of a rectangle
         cd.drawRectangle(100, 100, 200, 100);
         // Draws a filled Square
         cd.fillSquare(180, 150, 80);

         // Changes the color to light blue
         cd.setColor(Palette.LIGHT_BLUE);
         cd.fillCircle(300, 200, 50);

         // Finally, the method cd.show() must be called
         // to display the drawn shapes in the CodeDraw window.
         cd.show();
     }
 }
