Adding delay in Processing - random

Question

so I am new to Processing and basically I am doing a program that when it runs, it opens a window with 4 different images, each of the image have description underneath. In the methods below, I created two random methods, one for the reviews number and the other for the review comments, I would like the comments to not be generated all the time for every film - more like popping up randomly, because it cause too much chaos trying to read them all. Also to check weather I can add arrays together of string and integer for the average value of the review number.
Below is the code, would appreciate your help. thanks.
import g4p_controls.*;

PImage img1,img2; // background images for two different windows

String[] rev_film3 = {"Soul-less,Confused,Loud.","Devastatingly Disappointed","A technical masterpiece","A visual wonder that lacks depth"}; //Dunkirk

Please try to post a MCVE instead of your full program. For example, try creating a simple sketch that shows a circle every X seconds. That way we can focus on your problem instead of all the extra stuff that has nothing to do with your question.
But to answer your question, you can use the millis() function or the frameCount variable to check how much time has gone by, then do something every X seconds or every X frames.

Please also consult the Processing reference for more information.
If you still can't get it working, please post a MCVE (not your full project!) in a new question and we'll go from there. Good luck.
