public static void main

for example this bit looks more like pure Java and not like processing afaik

processing is with draw() afaik

     void setup() {
       size(400, 400);
       stroke(255);
     }

     void draw() {
       background(192, 64, 0);
       line(150, 25, mouseX, mouseY);
     }
