Processing: Creative Coding and Computational Art

Working in Java, creating even the simplest animation is a little complicated, as you need
to explicitly create a separate thread. In contrast, animation in Processing couldn’t be simpler.
To illustrate this difference, I’ve coded a simple animation using Java, followed by the
same animation using Processing’s draw() function (which encapsulates the thread creation
process for us). The Java version is written to be run within Processing.
// Animation in Java using a thread
// This code should run ok in Processing
void setup(){
size(400, 400);
new SimpleAnimation();
}
class SimpleAnimation implements Runnable{
int x, xspd = 3;
//constructor
SimpleAnimation(){
Thread t = new Thread(this);
t.start();
}
void run() {
while (x
