ProcessingをJavaから呼び出す方法について

import processing.core.*;

public class App extends PApplet {
    public static void main(String args[]) {
        PApplet.main(new String[] { "--present", App.class.getName() });
    }

    @Override
    public void settings() {
        size(720, 720);
    }

    @Override
    public void setup() {}

    @Override
    public void draw() {
        background(255);
        circle(width / 2, height / 2, 100);
