Is there any easy way to convert p5.js code to processing (java)?

Ok it looks like I need to know some of both languages to work efficiently between the two

JavaScript is Java on the web. It means both languages got a lot in common! ☕  
Even though you wanna go back to “offline” Java, it shouldn’t be that difficult at all: 😇

Just take a look at my Reddit post and compare how the same sketches are written in Java & JS syntaxes. 😀

I have found that this is true! But I have - as it is very easy to - gotten used to the whole var/auto data type

JavaScript and Java are actually completely different languages. The name JavaScript was chosen to ride the coattails of Java’s success.

Do you know any additional guide/tutorials other than the [Processing-transition](https://github.com/processing/p5.js/wiki/Processing-transition) wiki page? It seems there are several tools at GitHub to experiment automated conversion on java-processing to p5.js code but not the opposite.  
Do you know by chance any sketch examples exposing both language code, in order to study/compare the differences?

Haven’t you taken a look at my Reddit link from my 1st reply for this topic btW? 🙈

Anyways, I’ve got quite some more Java + p5js sketches for you to compare both syntax flavors: 🍦

wow… it seems I have missed this obvious post… But It is nice to see those examples as headlines here. Very Hard to miss them now… thanks!
