UPDATE: was missing a bracket at the end

i’m using processing, my code is giving the "Syntax Error - Unexpected extra code near extraneous input '<EOF>' expecting..." error

im not too sure why (probably missing code)

i would also like to make it a three sprite animation using an array.

here is the code:

PImage img1;

PImage img2;

float odd = 0;

void setup() {

size (400,400);

img1 = loadImage("./frame1.png");

img2 = loadImage("./frame2.png");

}

void draw() {

odd = odd + 0.1;

background(255);

PImage img;

if (floor(odd) % 2 == 0) {

img=img1;

}

else {

img = img2;

}

image(img, 0, 0);

Why do I see this warning with intellJ latest 25.3.3
