Java!

void setup(){
  size(500, 500);
}

void draw(){
  background(64);
  ellipse(mouseX, mouseY, 20, 20);
}

BECOMES:

import processing.core.PApplet;

public class MySketch extends PApplet {

	public void settings() {
		size(500, 500);
	}

	public void draw(){
		background(64);
		ellipse(mouseX, mouseY, 20, 20);
	}
  
	public static void main(String[] passedArgs) {
		String[] appletArgs = new String[] { "MySketch" };
		PApplet.main(appletArgs);
    }
}

This works because Processing is written in Java. So the Processing editor can take your Processing code and make a few minor adjustments, such as putting it inside a class inside a .java file, to create valid Java code. Then it compiles and runs that Java code, exactly how we’ve been compiling and running our Java code in these tutorials.
